Description:
This application is a continuation of U.S. patent application Ser. No. 15/488,734, filed Apr. 17, 2017, which is a divisional of U.S. patent application Ser. No. 13/339,248, filed Dec. 28, 2011, now U.S. Pat. No. 9,625,447, which is a divisional of U.S. patent application Ser. No. 12/722,801, filed Mar. 12, 2010, now U.S. Pat. No. 8,361,789, which claims priority pursuant to 35 U.S.C. § 119(e) to U.S. Provisional patent Application No. 61/160,199, filed Mar. 13, 2009, each of which is incorporated entirely by reference. 
    
    
     The sequences disclosed in the present specification are contained in the Sequence Listing submitted with the present specification which is hereby incorporated by reference in its entirety. 
     The ability of Clostridial toxins, such as, e.g., Botulinum neurotoxins (BoNTs), BoNT/A, BoNT/B, BoNT/C1, BoNT/D, BoNT/E, BoNT/F and BoNT/G, and Tetanus neurotoxin (TeNT), to inhibit neuronal transmission are being exploited in a wide variety of therapeutic and cosmetic applications, see e.g., William J. Lipham, Cosmetic and Clinical Applications of Botulinum Toxin (Slack, Inc., 2004). Clostridial toxins commercially available as pharmaceutical compositions include, BoNT/A preparations, such as, e.g., BOTOX® (Allergan, Inc., Irvine, Calif.), DYSPORT®/RELOXIN®, (Ipsen Ltd., Slough, England), PURTOX® (Mentor Corp., Santa Barbara, Calif.), XEOMIN® (Merz Pharmaceuticals, GmbH., Frankfurt, Germany), NEURONOX® (Medy-Tox, Inc., Ochang-myeon, South Korea), BTX-A (Biogen-tech Ltd., University, Yantai, Shandong, China); and BoNT/B preparations, such as, e.g., MYOBLOC®/NEUROBLOC® (Solstice Neurosciences, Inc., South San Francisco, Calif.). As an example, BOTOX® is currently approved in one or more countries for the following indications: achalasia, adult spasticity, anal fissure, back pain, blepharospasm, bruxism, cervical dystonia, essential tremor, glabellar lines or hyperkinetic facial lines, headache, hemifacial spasm, hyperactivity of bladder, hyperhidrosis, juvenile cerebral palsy, multiple sclerosis, myoclonic disorders, nasal labial lines, spasmodic dysphonia, strabismus and VII nerve disorder. 
     At present the mouse LD 50  bioassay, a lethality test, remains the “gold standard” test used by all pharmaceutical manufacturers to express the potency of their preparations. S. S. Arnon et al., JAMA 285: 1059-1070 (2001). In fact, the units on the pharmaceutical preparations&#39; labels are mouse LD 50  units and the number of animals needed to produce statistically useful LD 50  data is large. The advantage of the mouse LD 50  bioassay is that it measures all the steps necessary for botulinum toxin uptake (e.g., toxin binding to a cell surface receptor, internalization of the toxin-receptor complex, light chain translocation into the cytoplasm, light chain cleavage of substrate), instead of merely determining the activity for only part of this intoxication process, such as, e.g., in vitro assays that only measure light chain enzymatic activity. Unfortunately, the mouse LD 50  bioassay suffers from many drawbacks including high operational cost due to the large numbers of laboratory animals required, a lack of specificity since all BoNT serotypes will cause the same measurable end-point, and the potential for inaccuracy unless large animal groups are used. In addition, animal rights groups have exerted pressure on regulatory agencies in the United States (FDA/NICEATM/ICCVAM) and Europe (MHRA and EDQM), and on pharmaceutical companies manufacturing botulinum neurotoxin products to reduce animal testing and more importantly replace the mouse LD 50  bioassay for product release. The regulatory agencies are engaging pharmaceutical companies to apply the three “Rs” principle to the potency testing of botulinum neurotoxins: Reduce, Refine, Replace. D. Straughan,  Progress in Applying the Three Rs to the Potency Testing of Botulinum Toxin Type A , Altern. Lab. Anim. 34(3): 305-313 (2006). In recent years, several steps have been already taken to reduce and refine the mouse LD 50  bioassay in order to standardize the protocol and produce more consistent data using fewer animals per assay. 
     Thus, a simple, reliable, validated and governmental agency acceptable botulinum toxin activity assay that can evaluate the integrity of all the steps necessary in botulinum toxin uptake would be of significant value because such a non-animal based assay would alleviate the need for animal testing and all the disadvantages, costs and ethical concerns associated with this type of animal-based assay. Companion patent application Ester Fernandez-Salas, et al., Immuno-Based Botulinum Toxin Serotype A Activity Assays, U.S. patent application Ser. No. 12/403,531, provides novel compositions, cells, and methods for assaying the activity of a BoNT/A useful for various industries, such as, e.g., the pharmaceutical and food industries. Such compositions, cells, and methods do not use live animals or tissues taken from live animals, but can evaluate all the steps necessary for neurotoxin action, namely, binding and cellular uptake of toxin, translocation into the cell cytosol, and protease activity. 
     One of the necessary components for the methods disclosed in U.S. patent application Ser. No. 12/403,531 is the use of cells from an established cell line that are susceptible to low levels of BoNT/A intoxication because the amount of BoNT/A contained within a commercially-available pharmaceutical composition is very low. For example, approximately 4-5 ng of a BoNT/A complex is contained in the pharmaceutical composition sold as BOTOX®. Thus, there is a need to identify and create established cell lines comprising cells that are susceptible to BoNT/A intoxication when only very low levels of the neurotoxin is present in the sample. The present specification provides novel cells and cell compositions. that are susceptible to BoNT/A intoxication when only very low amounts of BoNT/A is present and thus allow assaying of commercially-available pharmaceutical composition comprising BoNT/A. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
         FIGS. 1A and 1B  show a schematic of the current paradigm of neurotransmitter release and Clostridial toxin intoxication in a central and peripheral neuron.  FIG. 1A  shows a schematic for the neurotransmitter release mechanism of a central and peripheral neuron. The release process can be described as comprising two steps: 1) vesicle docking, where the vesicle-bound SNARE protein of a vesicle containing neurotransmitter molecules associates with the membrane-bound SNARE proteins located at the plasma membrane; and 2) neurotransmitter release, where the vesicle fuses with the plasma membrane and the neurotransmitter molecules are exocytosed.  FIG. 1B  shows a schematic of the intoxication mechanism for tetanus and botulinum toxin activity in a central and peripheral neuron. This intoxication process can be described as comprising four steps: 1) receptor binding, where Clostridial toxin binding to a Clostridial receptor complex and initiates the intoxication process; 2) complex internalization, where after toxin binding, a vesicle containing a toxin/receptor system complex is endocytosed into the cell; 3) light chain translocation, where multiple events are thought to occur, including changes in the internal pH of the vesicle, formation of a channel pore comprising the H N  domain of Clostridial toxin heavy chain, separation of the Clostridial toxin light chain from the heavy chain, and release of the light chain and 4) enzymatic target modification, where the light chain of Clostridial toxin proteolytically cleaves its target SNARE substrates, such as, e.g., SNAP-25, VAMP or Syntaxin, thereby preventing vesicle docking and neurotransmitter release. 
         FIGS. 2A, 2B, 2C, 2D, and 2E  show volcano plots of genes that are more than 4-fold (log 2 (4)=2) up or down regulated in BB10 and H1 cell lines as compared to the 2D6 cell line.  FIG. 2A  shows the genes that are up regulated in the BB10 cell line as compared to the 2D6 cell line.  FIG. 2B  shows the genes that are up regulated in the H1 cell line as compared to the 2D6 cell line.  FIG. 2C  shows the genes that are up regulated in the BB10 cell line as compared to the parental SiMa cell line (PA).  FIG. 2D  shows the genes that are up regulated in the H1 cell line as compared to the parental SiMa cell line (PA).  FIG. 2E  shows the genes that are up regulated in the parental SiMa cell line (PA) as compared to the 2D6 cell line. Each dot represents a probe set. The dashed line marks the 95% confidence interval, p≤0.05. Most of the genes that are over expressed in BB10 and H1 compared to 2D6 (A and B) are also over or under-expressed in BB10 compared to PA (C), in H1 compared to PA (D), and in PA compared to 2D6 (E), however a number of them are less than 4-fold over-expressed and/or do not pass the 95% confidence interval. 
         FIGS. 3A and 3B  show normalized BIAcore SPR curves of 7.8 nM of the antibodies 2E2A6, 1D3B8, 3C1A5 and 2C9B10 and commercial MC-6050 and MC-6053.  FIG. 3A  shows the normalized data for the on-rate of each antibody.  FIG. 3B  shows the normalized data for the off-rate of each antibody. 
     
    
    
     DETAILED DESCRIPTION 
     The present specification provides novel cells and cell compositions that are susceptible to BoNT/A intoxication to allow assaying of BoNT/A and BoNT/A compositions such as, e.g., commercially-available pharmaceutical composition comprising BoNT/A. The cell and cell compositions disclosed in the present specification are useful to conduct methods that can detect picomolar quantities of BoNT/A in a sample, such as the methods disclosed in, e.g., Ester Fernandez-Salas, et al., Immuno-Based Botulinum Toxin Serotype A Activity Assays, U.S. patent application Ser. No. 12/403,531, which is hereby incorporated by reference in its entirety. The cells and cell compositions, and their use in methods of detecting BoNT/A activity reduce the need for animal toxicity studies, yet serve to analyze the multiple steps of BoNT/A intoxication, namely, binding and cellular uptake of toxin, translocation into the cell cytosol, and protease activity. As discussed further below, the novel cells and cell compositions of the present specification can be used in assays that analyze crude and bulk samples as well as highly purified di-chain toxins and formulated toxin products and further are amenable to automated high throughput assay formats. 
     Thus, aspects of the present specification provide a cell composition comprising cells from a clonal cell line that are susceptible to BoNT/A intoxication. 
     Other aspects of the present specification provide a method of detecting BoNT/A activity using the clonal cell lines disclosed in the present specification. 
     Clostridia toxins produced by  Clostridium botulinum, Clostridium tetani, Clostridium baratii  and  Clostridium butyricum  are the most widely used in therapeutic and cosmetic treatments of humans and other mammals. Strains of  C. botulinum  produce seven antigenically-distinct serotypes of botulinum toxins (BoNTs), which have been identified by investigating botulism outbreaks in man (BoNT/A, BoNT/B, BoNT/E and BoNT/F), animals (BoNT/C1 and BoNT/D), or isolated from soil (BoNT/G). While all seven botulinum toxin serotypes have similar structure and biological properties, each also displays heterogeneous characteristics, such as, e.g., different pharmacological properties. In contrast, tetanus toxin (TeNT) is produced by a uniform group of  C. tetani . Two other species of Clostridia,  C. baratii  and  C. butyricum , also produce toxins similar to BoNT/F and BoNT/E, respectively. 
     Clostridial toxins are each translated as a single chain polypeptide of approximately 150 kDa that is subsequently cleaved by proteolytic scission within a disulfide loop by a naturally-occurring protease, such as, e.g., an endogenous Clostridial toxin protease or a naturally-occurring protease produced in the environment. This posttranslational processing yields a di-chain molecule comprising an approximately 50 kDa light chain (LC) and an approximately 100 kDa heavy chain (HC) held together by a single disulfide bond and noncovalent interactions. Each mature di-chain molecule comprises three functionally distinct domains: 1) an enzymatic domain located in the LC that includes a metalloprotease region containing a zinc-dependent endopeptidase activity which specifically targets core components of the neurotransmitter release apparatus; 2) a translocation domain contained within the amino-terminal half of the HC (H N ) that facilitates release of the LC from intracellular vesicles into the cytoplasm of the target cell; and 3) a binding domain found within the carboxyl-terminal half of the HC (H C ) that determines the binding activity and binding specificity of the toxin to the receptor complex located at the surface of the target cell. 
     The binding, translocation and enzymatic activity of these three functional domains are all necessary for toxicity. While all details of this process are not yet precisely known, the overall cellular intoxication mechanism whereby Clostridial toxins enter a neuron and inhibit neurotransmitter release is similar, regardless of serotype or subtype. Although the applicants have no wish to be limited by the following description, the intoxication mechanism can be described as comprising at least four steps: 1) receptor binding, 2) complex internalization, 3) light chain translocation, and 4) enzymatic target modification ( FIG. 1 ). The process is initiated when the H C  binding domain of a Clostridial toxin binds to a toxin-specific receptor system located on the plasma membrane surface of a target cell. The binding specificity of a receptor complex is thought to be achieved, in part, by specific combinations of gangliosides and protein receptors that appear to distinctly comprise each Clostridial toxin receptor complex. Once bound, the toxin/receptor complexes are internalized by endocytosis and the internalized vesicles are sorted to specific intracellular routes. The translocation step appears to be triggered by the acidification of the vesicle compartment. This process seems to initiate important pH-dependent structural rearrangements that increase hydrophobicity, promote pore formation, and facilitate separation of the heavy and light chains of the toxin. Once separated, the light chain endopeptidase of the toxin is released from the intracellular vesicle into the cytosol where it appears to specifically target core components of the neurotransmitter release apparatus. These core proteins, vesicle-associated membrane protein (VAMP)/synaptobrevin, synaptosomal-associated protein of 25 kDa (SNAP-25) and Syntaxin, are necessary for synaptic vesicle docking and fusion at the nerve terminal and constitute members of the soluble N-ethylmaleimide-sensitive factor-attachment protein-receptor (SNARE) family. BoNT/A and BoNT/E cleave SNAP-25 in the carboxyl terminal region, releasing a nine or twenty six amino acid fragment, respectively, and BoNT/C1 also cleaves SNAP-25 near the carboxyl terminus releasing an eight amino acid fragment. The botulinum serotypes BoNT/B, BoNT/D, BoNT/F and BoNT/G, and tetanus toxin, act on the conserved central portion of VAMP, and release the amino terminal portion of VAMP into the cytosol. BoNT/C1 cleaves syntaxin at a single site near the cytosolic membrane surface. The selective proteolysis of synaptic SNAREs accounts for the block of neurotransmitter release caused by Clostridial toxins in vivo. The SNARE protein targets of Clostridial toxins are common to exocytosis in a variety of non-neuronal types; in these cells, as in neurons, light chain peptidase activity inhibits exocytosis, see, e.g., Yann Humeau et al.,  How Botulinum and Tetanus Neurotoxins Block Neurotransmitter Release,  82(5) Biochimie. 427-446 (2000); Kathryn Turton et al.,  Botulinum and Tetanus Neurotoxins: Structure, Function and Therapeutic Utility,  27(11) Trends Biochem. Sci. 552-558. (2002); Giovanna Lalli et al.,  The Journey of Tetanus and Botulinum Neurotoxins in Neurons,  11(9) Trends Microbiol. 431-437, (2003). 
     Aspects of the present disclosure comprise, in part, a cell from an established cell line. As used herein, the term “cell” refers to any eukaryotic cell susceptible to BoNT/A intoxication by a BoNT/A or any eukaryotic cell that can uptake a BoNT/A. The term cell encompasses cells from a variety of organisms, such as, e.g., murine, rat, porcine, bovine, equine, primate and human cells; from a variety of cell types such as, e.g., neuronal and non-neuronal; and can be isolated from or part of a heterogeneous cell population, tissue or organism. As used herein, the term “established cell line” is synonymous with “immortal cell line,” or “transformed cell line” and refers to a cell culture of cells selected for indefinite propagation from a cell population derived from an organism, tissue, or organ source. By definition, an established cell line excludes a cell culture of primary cells. As used herein, the term “primary cells” are cells harvested directly from fresh tissues or organs and do not have the potential to propagate indefinitely. An established cell line can comprise a heterogeneous population of cells or a uniform population of cells. An established cell line derived from a single cell is referred to as a clonal cell line. An established cell line can be one whose cells endogenously express all component necessary for the cells to undergo the overall cellular mechanism whereby a BoNT/A proteolytically cleaves a SNAP-25 substrate and encompasses the binding of a BoNT/A to a BoNT/A receptor, the internalization of the neurotoxin/receptor complex, the translocation of the BoNT/A light chain from an intracellular vesicle into the cytoplasm and the proteolytic cleavage of a SNAP-25. Alternatively, an established cell line can be one whose cells have had introduced from an exogenous source at least one component necessary for the cells to undergo the overall cellular mechanism whereby a BoNT/A proteolytically cleaves a SNAP-25 substrate and encompasses the binding of a BoNT/A to a BoNT/A receptor, the internalization of the neurotoxin/receptor complex, the translocation of the BoNT/A light chain from an intracellular vesicle into the cytoplasm and the proteolytic cleavage of a SNAP-25. Also referred to as a genetically-engineered cell line, cells from such an established cell line may, e.g., express an exogenous FGFR2, an exogenous FGFR3, an exogenous SV2, an exogenous SNAP-25, or any combination thereof. As used herein, the term “established clonal cell line” or “clonal cell line” refers to a cell culture of cells selected from a heterogenous population of cell types comprising an established cell line, which can also be referred to as a parental cell line.

By definition, cell(s) susceptible to BoNT/A intoxication must express, or be engineered to express, at least one BoNT/A receptor and at least one SNAP-25 substrate. Non-limiting examples of a cell or cells from an established clonal cell line susceptible to BoNT/A intoxication, include A6, A7, A9, A10, A11, B5, B10, C5, C11, C12, D7, D11, E11, F10, H1, H3, H8, H10, 1E3, 2B9, 2D2, 2D6, 2E4, 3B8, 3D5, 3G10, 4B5, 4C8, 4D3, 5C10, 5F3, AC9, AF4, BB3, BB10, BE3, BF8, CC11, CD6, CE6, CG8, CG10, DC4, DD10, DE7, DF5, YB7, YF5, and H1 1.4 clonal cell lines. As used herein, the terms “cell(s) that can uptake BoNT/A” or “cell(s) comprising an established clonal cell line that can uptake BoNT/A” refer to cells that can undergo the overall cellular mechanism whereby a BoNT/A proteolytically cleaves a SNAP-25 substrate and encompasses the binding of a BoNT/A to a BoNT/A receptor, the internalization of the neurotoxin/receptor complex, the translocation of the BoNT/A light chain from an intracellular vesicle into the cytoplasm and the proteolytic cleavage of a SNAP-25.

Cell lines comprising cell(s) from an established clonal cell line susceptible to BoNT/A intoxication or cell(s) that can uptake BoNT/A are referred to as a “responder cell line.” 
     Aspects of the present disclosure comprise, in part, cells from an established clonal cell line more susceptible to BoNT/A intoxication.

     Aspects of the present disclosure comprise, in part, cells from an established clonal cell line susceptible to BoNT/A intoxication that are more stable than cells from a parental SiMa cell line, such as, e.g., parental SiMa cell line DSMZ ACC 164. As used herein, the term “stable” refers to cells from an established clonal cell line for a particular passage number that exhibit a relative E050, sensitivity, efficacy, well-defined upper asymptote, and/or a well-defined dose-response curve for BoNT/A activity that is similar to the values for relative E050, sensitivity, efficacy, well-defined upper asymptote, and/or a well-defined dose-response curve exhibited by cells from a parental SiMa cell line, such as, e.g., parental SiMa cell line DSMZ ACC 164, at the same or similar passage number, where the same assay conditions and the same BoNT/A (or molecule) are used in both assays. 
     Thus in an embodiment, cells from an established clonal cell line are more stable as compared to a parental SiMa cell line. In an aspect of this embodiment, cells from an established clonal cell line are more stable as compared to the parental SiMa cell line DSMZ ACC 164.

     Aspects of the present disclosure comprise, in part, cells from an established clonal cell line susceptible to BoNT/A intoxication that are stable over a plurality of cell passages. As used herein, the term “stable” refers to cells from an established clonal cell line for a particular passage number that exhibit a relative E050, sensitivity, efficacy, well-defined upper asymptote, and/or a well-defined dose-response curve for BoNT/A activity that is similar to the values for relative E050, sensitivity, efficacy, well-defined upper asymptote, and/or a well-defined dose-response curve exhibited by cells from the same established clonal cell line, but from a prior passage or passages, where the same assay conditions and the same BoNT/A (or molecule) are used in both assays. 
     Cells from an established cell line disclosed in the present specification can exhibit consistent sensitivity to BoNT/A activity over a plurality of cell passages. As used herein, the term “sensitivity to BoNT/A activity” refers to the lowest dose that an assay can measure consistently above the signal detected by a non-treatment control or background signal.

In aspects of this embodiment, cells from the established clonal cell line exhibit a sensitivity for BoNT/A activity for any given passages that is, e.g., about 0.01 pM to about 100 pM, about 0.01 pM to about 75 pM, about 0.01 pM to about 50 pM, about 0.01 pM to about 25 pM, about 0.01 pM to about 20 pM, about 0.01 pM to about 15 pM, about 0.01 pM to about 10 pM, about 0.01 pM to about 5 pM, about 0.001 pM to about 100 pM, about 0.001 pM to about 75 pM, about 0.001 pM to about 50 pM, about 0.001 pM to about 25 pM, about 0.001 pM to about 20 pM, about 0.001 pM to about 15 pM, about 0.001 pM to about 10 pM, or about 0.001 pM to about 5 pM of BoNT/A.

In other aspects of this embodiment, cells from the established clonal cell line exhibit a sensitivity for BoNT/A activity that is about 100 pM or less, about 75 pM or less, about 50 pM or less, about 25 pM or less, less about 20 pM or less, about 15 pM or less, about 10 pM or less, or about 1 pM or less for, e.g., about 15 to about 60 passages, about 20 to about 60 passages, about 25 to about 60 passages, about 30 to about 60 passages, about 35 to about 60 passages, about 40 to about 60 passages, about 45 to about 60 passages, about 50 to about 60 passages, about 15 to about 50 passages, about 20 to about 50 passages, about 25 to about 50 passages, about 30 to about 50 passages, about 35 to about 50 passages, about 40 to about 50 passages, about 15 to about 40 passages, about 20 to about 40 passages, about 25 to about 40 passages, or about 30 to about 40 passages. 
     Cells from an established cell line disclosed in the present specification can exhibit a consistent relative efficacy of BoNT/A uptake, BoNT/A activity, or BoNT/A intoxication over a plurality of cell passages. As used herein, the term “relative efficacy” refers to how well the upper asymptote for the BoNT/A activity detected in the current assay run compares to the upper asymptote for the BoNT/A activity detected in a reference standard, a reference molecule, or a reference passage number used on that assay. As used herein, the term “signal to noise ratio for the upper asymptote” refers to the signal detected in an assay at the upper limit of detection divided by the signal detected by a non-treatment control or background signal. The upper limit of detection is the highest dose that an assay can measure consistently before saturation of the signal occurs. 
     Thus, in an embodiment, cells from an established cell line disclosed in the present specification can exhibit a well defined upper asymptote over a plurality of cell passages and maintain a signal to noise ratio that is consistent and adequate for the assay. In aspects of this embodiment, cells from an established cell line disclosed in the present specification must have a signal to noise ratio for the upper asymptote for BoNT/A activity of, e.g., at least 3:1, at least 4:1, at least 5:1, at least 6:1, at least 7:1, at least 8:1, at least 9:1, at least 10:1, at least 15:1, at least 20:1, at least 25:1, at least 30:1, at least 35:1, at least 40:1, at least 45:1, at least 50:1, at least 60:1, at least 70:1, at least 80:1, at least 90:1, or at least 100:1, at least 150:1, at least 200:1, at least 250:1, at least 300:1, at least 350:1, at least 400:1, at least 450:1, at least 500:1, at least 550:1, or at least 600:1, over, e.g., 5 or more cell passages, 10 or more cell passages, 15 or more cell passages, 20 or more cell passages, 25 or more cell passages, 30 or more cell passages, 35 or more cell passages, 40 or more cell passages, 45 or more cell passages, or 50 or more cell passages. In other aspects of this embodiment, cells from an established cell line disclosed in the present specification must have a signal to noise ratio for the upper asymptote for BoNT/A activity of, e.g., at least 3:1, at least 4:1, at least 5:1, at least 6:1, at least 7:1, at least 8:1, at least 9:1, at least 10:1, at least 15:1, at least 20:1, at least 25:1, at least 30:1, at least 35:1, at least 40:1, at least 45:1, at least 50:1, at least 60:1, at least 70:1, at least 80:1, at least 90:1, or at least 100:1, at least 150:1, at least 200:1, at least 250:1, at least 300:1, at least 350:1, at least 400:1, at least 450:1, at least 500:1, at least 550:1, or at least 600:1, over, e.g., about 15 to about 60 passages, about 20 to about 60 passages, about 25 to about 60 passages, about 30 to about 60 passages, about 35 to about 60 passages, about 40 to about 60 passages, about 45 to about 60 passages, about 50 to about 60 passages, about 15 to about 50 passages, about 20 to about 50 passages, about 25 to about 50 passages, about 30 to about 50 passages, about 35 to about 50 passages, about 40 to about 50 passages, about 15 to about 40 passages, about 20 to about 40 passages, about 25 to about 40 passages, or about 30 to about 40 passages. 
     Cells from an established cell line disclosed in the present specification can exhibit a well defined dose-response curve for BoNT/A activity over a plurality of cell passages. As used herein, the term “dose-response curve” refers to the how well the raw data fits the statistical model of choice for that assay. As a non-limiting example, a sigmoidal curve with a four parameter logistics fit is a dose-response curve for an enzymatic activity assay, such as, e.g., a potency assay. As another non-limiting example, a ligand binding with one site saturation fit is a dose-response curve for a ligand/antibody binding assay. 
     Thus, in an embodiment, cells from an established cell line disclosed in the present specification exhibit a well defined dose-response curve for BoNT/A activity over a plurality of cell passages. In aspects of this embodiment, cells from an established cell line disclosed in the present specification exhibit a well defined dose-response curve for BoNT/A activity over, e.g., 5 or more cell passages, 10 or more cell passages, 15 or more cell passages, 20 or more cell passages, 25 or more cell passages, 30 or more cell passages, 35 or more cell passages, 40 or more cell passages, 45 or more cell passages, or 50 or more cell passages.

     Cells from an established cell line disclosed in the present specification can exhibit a consistent relative EC 50  value for BoNT/A activity over a plurality of cell passages. As used herein, the term “relative EC 50 ” or “relative EC 50  value” refers to an EC 50  value of BoNT/A activity that is normalized against the EC 50  calculated for a reference standard, a reference molecule, or a reference passage number used on that assay. 
     Thus, in an embodiment, cells from an established clonal cell line exhibit a consistent relative EC 50  for BoNT/A activity over a plurality of cell passages. In aspects of this embodiment, cells from an established clonal cell line exhibit a consistent relative EC 50  for BoNT/A activity that is, e.g., about ±10%, about ±20%, about ±30%, about ±40%, about ±50%, about 60%, about 70%, or about ±75%, the relative EC 50  for BoNT/A activity over, e.g., 5 or more cell passages, 10 or more cell passages, 15 or more cell passages, 20 or more cell passages, 25 or more cell passages, 30 or more cell passages, 35 or more cell passages, 40 or more cell passages, 45 or more cell passages, or 50 or more cell passages.

     A SNAP-25 can be an endogenous SNAP-25 or an exogenous SNAP-25. As used herein, the term “endogenous SNAP-25” refers to a SNAP-25 naturally present in the cell because it is naturally encoded within the cell&#39;s genome, such that the cell inherently expresses the SNAP-25 without the need of an external source of SNAP-25 or an external source of genetic material encoding a SNAP-25. The expression of an endogenous SNAP-25 may be with or without environmental stimulation such as, e.g., cell differentiation. By definition, an endogenous SNAP-25 can only be a naturally-occurring SNAP-25 or variants thereof. For example, the following established cell lines express an endogenous SNAP-25: BE(2)-M17, Kelly, LA1-55n, N1E-115, N4TG3, N18, Neuro-2a, NG108-15, PC12, SH-SY5Y, SiMa, and SK-N-BE(2)-C. 
     As used herein, the term “exogenous SNAP-25” refers to a SNAP-25 expressed in a cell through the introduction of an external source of SNAP-25 or an external source of genetic material encoding a SNAP-25 by human manipulation. The expression of an exogenous SNAP-25 may be with or without environmental stimulation such as, e.g., cell differentiation. As a non-limiting example, cells from an established clonal cell line can express an exogenous SNAP-25 by transient or stably transfection of a SNAP-25 coding sequence. As another non-limiting example, cells from an established clonal cell line can express an exogenous SNAP-25 by protein transfection of a SNAP-25. An exogenous SNAP-25 can be a naturally-occurring SNAP-25 or variants thereof, or a non-naturally occurring SNAP-25 or variants thereof. 
     Thus in an embodiment, cells from an established clonal cell line express an endogenous SNAP-25. In aspects of this embodiment, the endogenous SNAP-25 expressed by cells from an established clonal cell line is a naturally-occurring SNAP-25. In other aspects of this embodiment, the endogenous SNAP-25 expressed by cells from an established clonal cell line is SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, SEQ ID NO: 8, SEQ ID NO: 9, SEQ ID NO: 10, SEQ ID NO: 11, SEQ ID NO: 12, SEQ ID NO: 13, SEQ ID NO: 14, SEQ ID NO: 15, SEQ ID NO: 16, SEQ ID NO: 17, SEQ ID NO: 18, SEQ ID NO: 19, SEQ ID NO: 20, SEQ ID NO: 21, SEQ ID NO: 22, SEQ ID NO: 23, or SEQ ID NO: 24. In yet other aspects of this embodiment, the endogenous SNAP-25 expressed by cells from an established clonal cell line is a naturally occurring SNAP-25, such as, e.g., a SNAP-25 isoform or a SNAP-25 subtype. In other aspects of this embodiment, the endogenous SNAP-25 expressed by cells from an established clonal cell line is a naturally occurring SNAP-25 having, e.g., at least 70% amino acid identity, at least 75%, at least 80%, at least 85%, at least 90%, or at least 95% amino acid identity with SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, SEQ ID NO: 8, SEQ ID NO: 9, SEQ ID NO: 10, SEQ ID NO: 11, SEQ ID NO: 12, SEQ ID NO: 13, SEQ ID NO: 14, SEQ ID NO: 15, SEQ ID NO: 16, SEQ ID NO: 17, SEQ ID NO: 18, SEQ ID NO: 19, SEQ ID NO: 20, SEQ ID NO: 21, SEQ ID NO: 22, SEQ ID NO: 23, or SEQ ID NO: 24. 
     In another embodiment, cells from an established clonal cell line are transiently or stably engineered to express an exogenous SNAP-25. In an aspect of this embodiment, cells from an established clonal cell line are transiently or stably engineered to express a naturally-occurring SNAP-25. In other aspects of this embodiment, cells from an established clonal cell line are transiently or stably engineered to express the naturally-occurring SNAP-25 of SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, SEQ ID NO: 8, SEQ ID NO: 9, SEQ ID NO: 10, SEQ ID NO: 11, SEQ ID NO: 12, SEQ ID NO: 13, SEQ ID NO: 14, SEQ ID NO: 15, SEQ ID NO: 16, SEQ ID NO: 17, SEQ ID NO: 18, SEQ ID NO: 19, SEQ ID NO: 20, SEQ ID NO: 21, SEQ ID NO: 22, SEQ ID NO: 23, or SEQ ID NO: 24.

In other aspects of this embodiment, cells from an established clonal cell line are transiently or stably engineered to express a non-naturally occurring SNAP-25 having, e.g., 1 or more, 2 or more, 3 or more, 4 or more, 5 or more, 6 or more, 7 or more, 8 or more, 9 or more, 10 or more, 20 or more, 30 or more, 40 or more, 50 or more, or 100 or more non-contiguous amino acid substitutions, deletions, or additions relative to SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, SEQ ID NO: 8, SEQ ID NO: 9, SEQ ID NO: 10, SEQ ID NO: 11, SEQ ID NO: 12, SEQ ID NO: 13, SEQ ID NO: 14, SEQ ID NO: 15, SEQ ID NO: 16, SEQ ID NO: 17, SEQ ID NO: 18, SEQ ID NO: 19, SEQ ID NO: 20, SEQ ID NO: 21, SEQ ID NO: 22, SEQ ID NO: 23, or SEQ ID NO: 24. In yet other aspects of this embodiment, cells from an established clonal cell line are transiently or stably engineered to express a non-naturally occurring SNAP-25 having, e.g., 1 or more, 2 or more, 3 or more, 4 or more, 5 or more, 6 or more, 7 or more, 8 or more, 9 or more, 10 or more, 20 or more, 30 or more, 40 or more, 50 or more, or 100 or more contiguous amino acid substitutions, deletions, or additions relative to SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, SEQ ID NO: 8, SEQ ID NO: 9, SEQ ID NO: 10, SEQ ID NO: 11, SEQ ID NO: 12, SEQ ID NO: 13, SEQ ID NO: 14, SEQ ID NO: 15, SEQ ID NO: 16, SEQ ID NO: 17, SEQ ID NO: 18, SEQ ID NO: 19, SEQ ID NO: 20, SEQ ID NO: 21, SEQ ID NO: 22, SEQ ID NO: 23, or SEQ ID NO: 24. 
     Assays that detect the cleavage of a BoNT/A substrate after exposure to a BoNT/A can be used to assess whether a cell is expressing an endogenous or an exogenous SNAP-25. In these assays, generation of a SNAP-25 cleavage-product would be detected in cells expressing a SNAP-25 after BoNT/A treatment. Non-limiting examples of specific Western blot analysis, as well as well-characterized reagents, conditions and protocols are readily available from commercial vendors that include, without limitation, Amersham Biosciences, Piscataway, N.J.; Bio-Rad Laboratories, Hercules, Calif.; Pierce Biotechnology, Inc., Rockford, Ill.; Promega Corporation, Madison, Wis., and Stratagene, Inc., La Jolla, Calif. It is understood that these and similar assays for SNAP-25 cleavage can be useful in identifying cells expressing an endogenous or an exogenous SNAP-25. 
     As non-limiting examples, Western blot analysis using an antibody that recognizes BoNT/A SNAP-25-cleaved product or both the cleaved and uncleaved forms of SNAP-25 can be used to assay for uptake of BoNT/A. Examples of α-SNAP-25 antibodies useful for these assays include, without limitation, α-SNAP-25 mouse monoclonal antibody SMI-81 (Sternberger Monoclonals Inc., Lutherville, Md.), mouse α-SNAP-25 monoclonal antibody CI 71.1 (Synaptic Systems, Goettingen, Germany), α-SNAP-25 mouse monoclonal antibody CI 71.2 (Synaptic Systems, Goettingen, Germany), α-SNAP-25 mouse monoclonal antibody SP12 (Abcam, Cambridge, Mass.), α-SNAP-25 rabbit polyclonal antiserum (Synaptic Systems, Goettingen, Germany), α-SNAP-25 rabbit polyclonal antiserum (Abcam, Cambridge, Mass.), and α-SNAP-25 rabbit polyclonal antiserum S9684 (Sigma, St Louis, Mo.). 
     Aspects of the present disclosure comprise, in part, a BoNT/A receptor. As used herein, the term “BoNT/A receptor” refers to either a naturally-occurring BoNT/A receptor or a non-naturally occurring BoNT/A receptor which preferentially interacts with BoNT/A in a manner that elicits a BoNT/A intoxication response. As used herein, the term “preferentially interacts” refers to that the equilibrium dissociation constant (KD) of BoNT/A for a BoNT/A receptor is at least one order of magnitude less than that of BoNT/A for any other receptor. The equilibrium dissociation constant, a specific type of equilibrium constant that measures the propensity of an BoNT/A-BoNT/A receptor complex to separate (dissociate) reversibly into its component molecules, namely the BoNT/A and the BoNT/A receptor complex. The disassociation constant is defined as KD=[L][R]/[C], where [L] equals the molar concentration of BoNT/A, [R] is the molar concentration of a BoNT/A receptor, and [C] is the molar concentration of the BoNT/A-BoNT/A receptor complex, and where all concentrations are of such components when the system is at equilibrium. The smaller the dissociation constant, the more tightly bound the BoNT/A is to its receptor, or the higher the binding affinity between BoNT/A and BoNT/A receptor. In aspects of this embodiment, the disassociation constant of BoNT/A for a BoNT/A receptor is at least two orders of magnitude less, at least three orders of magnitude less, at least four orders of magnitude less, or at least five orders of magnitude less than that of BoNT/A for any other receptor. In other aspects of this embodiment, the binding affinity of a BoNT/A that preferentially interacts with a BoNT/A receptor can have an equilibrium disassociation constant of, e.g., of 500 nM or less, 400 nM or less, 300 nM or less, 200 nM, or less 100 nM or less. In other aspects of this embodiment, the binding affinity of a BoNT/A that preferentially interacts with a BoNT/A receptor can have an equilibrium disassociation constant of, e.g., of 90 nM or less, 80 nM or less, 70 nM or less, 60 nM or less, 50 nM or less, 40 nM or less, 30 nM or less, 20 nM, or less 10 nM or less. As used herein, the term “elicits a BoNT/A intoxication response” refers to the ability of a BoNT/A receptor to interact with a BoNT/A to form a neurotoxin/receptor complex and the subsequent internalization of that complex into the cell cytoplasm. 
     As used herein, the term “naturally occurring BoNT/A receptor” refers to any BoNT/A receptor produced by a naturally-occurring process, including, without limitation, BoNT/A receptor isoforms produced from a post-translational modification, an alternatively-spliced transcript, or a spontaneous mutation, and BoNT/A receptor subtypes.

A non-naturally occurring BoNT/A receptor may substitute, delete or add, e.g., 1 or more, 2 or more, 3 or more, 4 or more, 5 or more, 6 or more, 7 or more, 8 or more, 9 or more, 10 or more, 20 or more, 30 or more, 40 or more, 50 or more, or 100 or more amino acids from SEQ ID NO: 25, SEQ ID NO: 26, SEQ ID NO: 27, SEQ ID NO: 28, SEQ ID NO: 29, SEQ ID NO: 30, SEQ ID NO: 31, SEQ ID NO: 59, SEQ ID NO: 60, SEQ ID NO: 61, SEQ ID NO: 62, SEQ ID NO: 63, SEQ ID NO: 64, SEQ ID NO: 65, SEQ ID NO: 66, SEQ ID NO: 67, SEQ ID NO: 68, SEQ ID NO: 69, or SEQ ID NO: 70. 
     Thus in an embodiment, a BoNT/A receptor is a naturally occurring BoNT/A receptor such as, e.g., FGFR2, FGFR3 or SV2. In aspects of this embodiment, the BoNT/A receptor is a BoNT/A receptor isoform or a BoNT/A receptor subtype.

     In another embodiment, a BoNT/A receptor is a non-naturally occurring BoNT/A receptor, such as, e.g., a genetically-engineered FGFR2, a genetically-engineered FGFR3, or a genetically-engineered SV2. In other aspects of this embodiment, the BoNT/A receptor is a non-naturally occurring BoNT/A receptor having, e.g., at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, or at least 95% amino acid identity with SEQ ID NO: 25, SEQ ID NO: 26, SEQ ID NO: 27, SEQ ID NO: 28, SEQ ID NO: 29, SEQ ID NO: 30, SEQ ID NO: 31, SEQ ID NO: 59, SEQ ID NO: 60, SEQ ID NO: 61, SEQ ID NO: 62, SEQ ID NO: 63, SEQ ID NO: 64, SEQ ID NO: 65, SEQ ID NO: 66, SEQ ID NO: 67, SEQ ID NO: 68, SEQ ID NO: 69, or SEQ ID NO: 70. In other aspects of this embodiment, the BoNT/A receptor is a non-naturally occurring BoNT/A receptor having, e.g., 1 or more, 2 or more, 3 or more, 4 or more, 5 or more, 6 or more, 7 or more, 8 or more, 9 or more, 10 or more, 20 or more, 30 or more, 40 or more, 50 or more, or 100 or more non-contiguous amino acid substitutions, deletions, or additions relative to SEQ ID NO: 25, SEQ ID NO: 26, SEQ ID NO: 27, SEQ ID NO: 28, SEQ ID NO: 29, SEQ ID NO: 30, SEQ ID NO: 31, SEQ ID NO: 59, SEQ ID NO: 60, SEQ ID NO: 61, SEQ ID NO: 62, SEQ ID NO: 63, SEQ ID NO: 64, SEQ ID NO: 65, SEQ ID NO: 66, SEQ ID NO: 67, SEQ ID NO: 68, SEQ ID NO: 69, or SEQ ID NO: 70. In yet other aspects of this embodiment, the BoNT/A receptor is a non-naturally occurring BoNT/A receptor having, e.g., 1 or more, 2 or more, 3 or more, 4 or more, 5 or more, 6 or more, 7 or more, 8 or more, 9 or more, 10 or more, 20 or more, 30 or more, 40 or more, 50 or more, or 100 or more contiguous amino acid substitutions, deletions, or additions relative to SEQ ID NO: 25, SEQ ID NO: 26, SEQ ID NO: 27, SEQ ID NO: 28, SEQ ID NO: 29, SEQ ID NO: 30, SEQ ID NO: 31, SEQ ID NO: 59, SEQ ID NO: 60, SEQ ID NO: 61, SEQ ID NO: 62, SEQ ID NO: 63, SEQ ID NO: 64, SEQ ID NO: 65, SEQ ID NO: 66, SEQ ID NO: 67, SEQ ID NO: 68, SEQ ID NO: 69, or SEQ ID NO: 70. 
     A BoNT/A receptor can be an endogenous BoNT/A receptor or an exogenous BoNT/A receptor. As used herein, the term “endogenous BoNT/A receptor” refers to a BoNT/A receptor naturally present in the cell because it is naturally encoded within the cell&#39;s genome, such that the cell inherently expresses the BoNT/A receptor without the need an external source of BoNT/A receptor or an external source of genetic material encoding a BoNT/A receptor. Expression of an endogenous BoNT/A receptor may be with or without environmental stimulation such as e.g., cell differentiation or promoter activation. For example, the following established clonal cell lines express at least one endogenous BoNT/A receptor: BE(2)-M17, Kelly, LA1-55n, N1E-115, N4TG3, N18, Neuro-2a, NG108-15, PC12, SH-SY5Y, SiMa, and SK-N-BE(2)-C. An endogenous BoNT/A receptor can only be a naturally-occurring BoNT/A receptor or naturally-occurring variants thereof. 
     As used herein, the term “exogenous BoNT/A receptor” refers to a BoNT/A receptor expressed in a cell through the introduction of an external source of BoNT/A receptor or an external source of genetic material encoding a BoNT/A receptor by human manipulation. The expression of an exogenous BoNT/A receptor may be with or without environmental stimulation such as, e.g., cell differentiation or promoter activation. As a non-limiting example, cells from an established clonal cell line can express one or more exogenous BoNT/A receptors by transient or stably transfection of a polynucleotide molecule encoding a BoNT/A receptor, such as, e.g., a FGFR2, a FGFR3, or a SV2. As another non-limiting example, cells from an established clonal cell line can express one or more exogenous BoNT/A receptors by protein transfection of the BoNT/A receptors, such as, e.g., a FGFR2, a FGFR3, or a SV2. An exogenous BoNT/A receptor can be a naturally-occurring BoNT/A receptor or naturally occurring variants thereof, or non-naturally occurring BoNT/A receptor or non-naturally occurring variants thereof. 
     Thus in an embodiment, cells from an established clonal cell line express an endogenous BoNT/A receptor. In aspects of this embodiment, the endogenous BoNT/A receptor expressed by cells from an established clonal cell line is a naturally-occurring BoNT/A receptor. In other aspects of this embodiment, the endogenous BoNT/A receptor expressed by cells from an established clonal cell line is SEQ ID NO: 25, SEQ ID NO: 26, SEQ ID NO: 27, SEQ ID NO: 28, SEQ ID NO: 29, SEQ ID NO: 30, SEQ ID NO: 31, SEQ ID NO: 59, SEQ ID NO: 60, SEQ ID NO: 61, SEQ ID NO: 62, SEQ ID NO: 63, SEQ ID NO: 64, SEQ ID NO: 65, SEQ ID NO: 66, SEQ ID NO: 67, SEQ ID NO: 68, SEQ ID NO: 69, or SEQ ID NO: 70. In yet aspects of this embodiment, the endogenous BoNT/A receptor expressed by cells from an established clonal cell line is a naturally occurring BoNT/A receptor, such as, e.g., a BoNT/A receptor isoform or a BoNT/A receptor subtype. In other aspects of this embodiment, the endogenous BoNT/A receptor expressed by cells from an established clonal cell line is a naturally occurring BoNT/A receptor having, e.g., at least 70% amino acid identity, at least 75%, at least 80%, at least 85%, at least 90%, or at least 95% amino acid identity with SEQ ID NO: 25, SEQ ID NO: 26, SEQ ID NO: 27, SEQ ID NO: 28, SEQ ID NO: 29, SEQ ID NO: 30, SEQ ID NO: 31, SEQ ID NO: 59, SEQ ID NO: 60, SEQ ID NO: 61, SEQ ID NO: 62, SEQ ID NO: 63, SEQ ID NO: 64, SEQ ID NO: 65, SEQ ID NO: 66, SEQ ID NO: 67, SEQ ID NO: 68, SEQ ID NO: 69, or SEQ ID NO: 70.

In other aspects of this embodiment, cells from an established clonal cell line are transiently or stably engineered to express a non-naturally occurring BoNT/A receptor having, e.g., 1 or more, 2 or more, 3 or more, 4 or more, 5 or more, 6 or more, 7 or more, 8 or more, 9 or more, 10 or more, 20 or more, 30 or more, 40 or more, 50 or more, or 100 or more non-contiguous amino acid substitutions, deletions, or additions relative to SEQ ID NO: 25, SEQ ID NO: 26, SEQ ID NO: 27, SEQ ID NO: 28, SEQ ID NO: 29, SEQ ID NO: 30, SEQ ID NO: 31, SEQ ID NO: 59, SEQ ID NO: 60, SEQ ID NO: 61, SEQ ID NO: 62, SEQ ID NO: 63, SEQ ID NO: 64, SEQ ID NO: 65, SEQ ID NO: 66, SEQ ID NO: 67, SEQ ID NO: 68, SEQ ID NO: 69, or SEQ ID NO: 70. In yet other aspects of this embodiment, cells from an established clonal cell line are transiently or stably engineered to express a non-naturally occurring BoNT/A receptor having, e.g., 1 or more, 2 or more, 3 or more, 4 or more, 5 or more, 6 or more, 7 or more, 8 or more, 9 or more, 10 or more, 20 or more, 30 or more, 40 or more, 50 or more, or 100 or more contiguous amino acid substitutions, deletions, or additions relative to SEQ ID NO: 25, SEQ ID NO: 26, SEQ ID NO: 27, SEQ ID NO: 28, SEQ ID NO: 29, SEQ ID NO: 30, SEQ ID NO: 31, SEQ ID NO: 59, SEQ ID NO: 60, SEQ ID NO: 61, SEQ ID NO: 62, SEQ ID NO: 63, SEQ ID NO: 64, SEQ ID NO: 65, SEQ ID NO: 66, SEQ ID NO: 67, SEQ ID NO: 68, SEQ ID NO: 69, or SEQ ID NO: 70 
     In another embodiment, cells from an established clonal cell line are transiently or stably engineered to express an exogenous FGFR2, an exogenous FGFR3, an exogenous SV2, or any combination thereof. In aspects of this embodiment, cells from an established clonal cell line are transiently or stably engineered to express a naturally-occurring FGFR2, a naturally-occurring FGFR3, a naturally-occurring SV2, or any combination thereof. In yet other aspects of this embodiment, cells from an established clonal cell line are transiently or stably engineered to express a non-naturally-occurring FGFR2, a non-naturally-occurring FGFR3, a non-naturally-occurring SV2, or any combination thereof. In still other aspects of this embodiment, cells from an established clonal cell line are transiently or stably engineered to express either a naturally-occurring FGFR2 or a non-naturally-occurring FGFR2, a naturally-occurring FGFR3 or a non-naturally-occurring FGFR3, a naturally-occurring SV2 or a non-naturally-occurring SV2, or any combination thereof. 
     Cells that express one or more endogenous or exogenous BoNT/A receptors can be identified by routine methods including direct and indirect assays for toxin uptake. Assays that determine BoNT/A binding or uptake properties can be used to assess whether a cell is expressing a BoNT/A receptor. Such assays include, without limitation, cross-linking assays using labeled BoNT/A, such as, e.g., [ 125 I] BoNT/A, see, e.g., Noriko Yokosawa et al.,  Binding of Clostridium botulinum type C neurotoxin to different neuroblastoma cell lines,  57(1) Infect. Immun. 272-277 (1989); Noriko Yokosawa et al.,  Binding of botulinum type CI, D and E neurotoxins to neuronal cell lines and synaptosomes,  29(2) Toxicon 261-264 (1991); and Tei-ichi Nishiki et al.,  Identification of protein receptor for Clostridium botulinum type B neurotoxin in rat brain synaptosomes,  269(14) J. Biol. Chem. 10498-10503 (1994). Other non-limiting assays include immunocytochemical assays that detect BoNT/A binding using labeled or unlabeled antibodies, see, e.g., Atsushi Nishikawa et al.,  The receptor and transporter for internalization of Clostridium botulinum type C progenitor toxin into HT -29  cells,  319(2) Biochem. Biophys. Res. Commun. 327-333 (2004) and immunoprecipitation assays, see, e.g., Yukako Fujinaga et al.,  Molecular characterization of binding subcomponents of Clostridium botulinum type C progenitor toxin for intestinal epithelial cells and erythrocytes,  150(Pt 5) Microbiology 1529-1538 (2004), that detect bound toxin using labeled or unlabeled antibodies. Antibodies useful for these assays include, without limitation, antibodies selected against BoNT/A, antibodies selected against a BoNT/A receptor, such as, e.g., FGFR2, FGFR3, or SV2, and/or antibodies selected against a ganglioside, such as, e.g., GD1a, GD1b, GD3, GQ1b, or GT1b. If the antibody is labeled, the binding of the molecule can be detected by various means, including Western blot analysis, direct microscopic observation of the cellular location of the antibody, measurement of cell or substrate-bound antibody following a wash step, flow cytometry, electrophoresis or capillary electrophoresis, employing techniques well-known to those of skill in the art. If the antibody is unlabeled, one may employ a labeled secondary antibody for indirect detection of the bound molecule, and detection can proceed as for a labeled antibody. It is understood that these and similar assays that determine BoNT/A uptake properties or characteristics can be useful in identifying cells expressing endogenous or exogenous BoNT/A receptors. 
     Assays that monitor the release of a molecule after exposure to BoNT/A can also be used to assess whether a cell is expressing one or more endogenous or exogenous BoNT/A receptors. In these assays, inhibition of the molecule&#39;s release would occur in cells expressing a BoNT/A receptor after BoNT/A treatment. Well known assays include methods that measure inhibition of radio-labeled catecholamine release from neurons, such as, e.g., [3H] noradrenaline or [3H] dopamine release, see e.g., A Fassio et al.,  Evidence for calcium - dependent vesicular transmitter release insensitive to tetanus toxin and botulinum toxin type F,  90(3) Neuroscience 893-902 (1999); and Sara Stigliani et al.,  The sensitivity of catecholamine release to botulinum toxin C 1  and E suggests selective targeting of vesicles set into the readily releasable pool,  85(2) J. Neurochem. 409-421 (2003), or measures catecholamine release using a fluorometric procedure, see, e.g., Anton de Paiva et al.,  A role for the interchain disulfide or its participating thiols in the internalization of botulinum neurotoxin A revealed by a toxin derivative that binds to ecto - acceptors and inhibits transmitter release intracellularly,  268(28) J. Biol. Chem. 20838-20844 (1993); Gary W. Lawrence et al.,  Distinct exocytotic responses of intact and permeabilized chromaffin cells after cleavage of the  25- kDa synaptosomal - associated protein  ( SNAP -25)  or synaptobrevin by botulinum toxin A or B,  236(3) Eur. J. Biochem. 877-886 (1996); and Patrick Foran et al.,  Botulinum neurotoxin C 1  cleaves both syntaxin and SNAP -25  in intact and permeabilized chromaffin cells: correlation with its blockade of catecholamine release,  35(8) Biochemistry 2630-2636 (1996). Other non-limiting examples include assays that measure inhibition of hormone release from endocrine cells, such as, e.g., anterior pituitary cells or ovarian cells. It is understood that these and similar assays for molecule release can be useful in identifying cells expressing endogenous or exogenous or BoNT/A receptors. 
     Assays that detect the cleavage of a BoNT/A substrate after exposure to a BoNT/A can also be used to assess whether a cell is expressing one or more endogenous or exogenous BoNT/A receptors. In these assays, generation of a BoNT/A substrate cleavage-product, or disappearance of the intact BoNT/A substrate, would be detected in cells expressing a BoNT/A receptor after BoNT/A treatment. Non-limiting examples of specific Western blot analysis, as well as well-characterized reagents, conditions and protocols are readily available from commercial vendors that include, without limitation, Amersham Biosciences, Piscataway, N.J.; Bio-Rad Laboratories, Hercules, Calif.; Pierce Biotechnology, Inc., Rockford, Ill.; Promega Corporation, Madison, Wis., and Stratagene, Inc., La Jolla, Calif. It is understood that these and similar assays for BoNT/A substrate cleavage can be useful in identifying cells expressing endogenous or exogenous BoNT/A receptors. 
     As non-limiting examples, Western blot analysis using an antibody that recognizes BoNT/A SNAP-25-cleaved product or both the cleaved and uncleaved forms of SNAP-25 can be used to assay for uptake of BoNT/A. Examples of α-SNAP-25 antibodies useful for these assays include, without limitation, SMI-81 α-SNAP-25 mouse monoclonal antibody (Sternberger Monoclonals Inc., Lutherville, Md.), CI 71.1 mouse α-SNAP-25 monoclonal antibody (Synaptic Systems, Goettingen, Germany), CI 71.2 α-SNAP-25 mouse monoclonal antibody (Synaptic Systems, Goettingen, Germany), SP12 α-SNAP-25 mouse monoclonal antibody (Abcam, Cambridge, Mass.), α-SNAP-25 rabbit polyclonal antiserum (Synaptic Systems, Goettingen, Germany), α-SNAP-25 rabbit polyclonal antiserum S9684 (Sigma, St. Louis, Mo.), and α-SNAP-25 rabbit polyclonal antiserum (Abcam, Cambridge, Mass.). 
     Aspects of the present disclosure provide cells that through genetic manipulation or recombinant engineering are made to express an exogenous SNAP-25 and/or one or more exogenous BoNT/A receptors. Cells useful to express an exogenous SNAP-25 and/or one or more exogenous BoNT/A receptors through genetic manipulation or recombinant engineering include neuronal cells and non-neuronal cells that may or may not express an endogenous SNAP-25 and/or one or more endogenous BoNT/A receptors. It is further understood that such genetically manipulated or recombinantly engineered cells may express an exogenous SNAP-25 and one or more exogenous BoNT/A receptors under control of a constitutive, tissue-specific, cell-specific or inducible promoter element, enhancer element or both. It is understood that any cell is useful as long as the cell can be genetically manipulated or recombinantly engineered to expresses an exogenous SNAP-25 and/or one or more exogenous BoNT/A receptors and is capable of undergoing BoNT/A intoxication. 
     Methods useful for introducing into a cell an exogenous polynucleotide molecule encoding a component necessary for the cells to undergo the overall cellular mechanism whereby a BoNT/A proteolytically cleaves a SNAP-25 substrate, such as, e.g., a SNAP-25, a FGFR2, a FGFR3, or a SV2, include, without limitation, chemical-mediated delivery methods, such as, e.g., calcium phosphate-mediated, diethyl-aminoethyl (DEAF) dextran-mediated, lipid-mediated, polyethyleneimine (PEI)-mediated, polylysine-mediated and polybrene-mediated; physical-mediated delivery methods, such as, e.g., biolistic particle delivery, microinjection, protoplast fusion and electroporation; and viral-mediated delivery methods, such as, e.g., retroviral-mediated transfection, see e.g.,  Introducing Cloned Genes into Cultured Mammalian Cells , pp. 16.1-16.62 (Sambrook &amp; Russell, eds., Molecular Cloning A Laboratory Manual, Vol. 3, 3 rd  ed. 2001); Alessia Colosimo et al.,  Transfer and Expression of Foreign Genes in Mammalian Cells,  29(2) Biotechniques 314-318, 320-322, 324 (2000); Philip Washbourne &amp; A. Kimberley McAllister,  Techniques for Gene Transfer into Neurons,  12(5) Curr. Opin. Neurobiol. 566-573 (2002); and Current Protocols in Molecular Biology, John Wiley and Sons, pp 9.16.4-9.16.11 (2000), each of which is incorporated by reference in its entirety. One skilled in the art understands that selection of a specific method to introduce a polynucleotide molecule into a cell will depend, in part, on whether the cell will transiently or stably contain a component necessary for the cells to undergo the overall cellular mechanism whereby a BoNT/A proteolytically cleaves a SNAP-25 substrate. Non-limiting examples of polynucleotide molecule encoding a component necessary for the cells to undergo the overall cellular mechanism whereby a BoNT/A proteolytically cleaves a SNAP-25 substrate as follows: FGFR2 polynucleotide molecule of SEQ ID NO: 130, SEQ ID NO: 131, SEQ ID NO: 132, SEQ ID NO: 133, SEQ ID NO: 134, SEQ ID NO: 135, SEQ ID NO: 136, SEQ ID NO: 137, or SEQ ID NO: 138; FGFR3 polynucleotide molecule of SEQ ID NO: 139, SEQ ID NO: 140, or SEQ ID NO: 141; SV2 polynucleotide molecule of SEQ ID NO: 142, SEQ ID NO: 143, or SEQ ID NO: 144; and SNAP-25 polynucleotide molecule of SEQ ID NO: 145, or SEQ ID NO: 146.

     As mentioned above, an exogenous component necessary for the cells to undergo the overall cellular mechanism whereby a BoNT/A proteolytically cleaves a SNAP-25 substrate, such as, e.g., a SNAP-25, a FGFR2, a FGFR3, or a SV2 disclosed in the present specification can be introduced into a cell. Any and all methods useful for introducing such an exogenous component with a delivery agent into a cell population can be useful with the proviso that this method introduce the exogenous component disclosed in the present specification in at least 50% of the cells within a given cell population. Thus, aspects of this embodiment can include a cell population in which, e.g., at least 50%, at least 60%, at least 70%, at least 80%, or at least 90% of the given cell population contains an exogenous component necessary for the cells to undergo the overall cellular mechanism whereby a BoNT/A proteolytically cleaves a SNAP-25 substrate, such as, e.g., a SNAP-25, a FGFR2, a FGFR3, or a SV2 disclosed in the present specification. As used herein, the term “delivery agent” refers to any molecule that enables or enhances internalization of a covalently-linked, non-covalently-linked or in any other manner associated with a polypeptide into a cell. Thus, the term “delivery agent” encompasses, without limitation, proteins, peptides, peptidomimetics, small molecules, polynucleotide molecules, liposomes, lipids, viruses, retroviruses and cells that, without limitation, transport a covalently or non-covalently linked molecule to the cell membrane, cell cytoplasm or nucleus. It further is understood that the term “delivery agent” encompasses molecules that are internalized by any mechanism, including delivery agents which function via receptor mediated endocytosis and those which are independent of receptor mediated endocytosis. 
     A delivery agent can also be an agent that enables or enhances cellular uptake of a covalently linked component, like FGFR2, FGFR3, SV2, or SNAP-25, such as, e.g., by chemical conjugation or by genetically produced fusion proteins.

     EXAMPLES 
     Example I 
     Screening for Cell Lines Comprising Cells Susceptible to BoNT/A Intoxication 
     The following example illustrates how to identify clonal cells from a parental established cell line that are susceptible to BoNT/A intoxication or have neurotoxin uptake capacity. 
     1. Isolation of Clonal Cell Lines. 
     Companion patent application Ester Fernandez-Salas, et al., Immuno-Based Botulinum Toxin Serotype A Activity Assays, U.S. patent application Ser. No. 12/403,531 identified several established cell lines useful for conducting the disclosed immuno-based methods of detecting BoNT/A activity, including, e.g., LA1-55n (ECACC 06041203), N18 (ECACC 88112301), Neuro-2a (ATCC CCL-131), PC12 (ATCC CRL-1721), SH-SY5Y (ATCC CRL-2266), and SiMa (DSMZ ACC 164). During characterization of the SiMa cell line, it was discovered that the cells comprising this established cell line comprised at least five different cellular phenotypes. To determine whether any one of these phenotypically-distinct cell types was responsible for the susceptibility of this cell line to BoNT/A intoxication, two different limited-dilution screens were conducted to obtain single colony isolates for each phenotypically-distinct cell type. 
     In both screens, a suitable density of cells from a SiMa stock were grown in RPMI 1640 medium, having 10% fetal bovine serum, 1% Penicillin-Streptomycin, 2 mM L-Glutamine, contained in a T175 Collagen IV coated flask. After the second passage, the cells were trypsin-treated to produce a cell suspension and the cell concentration was determined. About 4.0×10 6  cells from this cell suspension was transferred into a 50 mL tube and the cells were dissociated into single cells by repeated vigorous expulsion through an 18.5 gauge needle using a 10 mL syringe. Cells from this disassociated single-cell suspension were then diluted to a concentration of 0.2×10 6  cells/mL by adding 15 mL of fresh growth medium, and 2.5 μL of this dilution was added to 50 mL of fresh growth medium to obtain a concentration of 10 cells/mL. From this final dilution stock, 100 μL of growth medium was added to each well of a 96-well Collagen IV coated plates (final average density of one cell/well), and the cells were grown undisturbed in a 37° C. incubator under 5% carbon dioxide for four weeks. A total of nineteen 96-well plates were setup for analysis. Plates were microscopically examined periodically to assess colony growth. After four weeks, each well was microscopically examined to identify growing colonies, and for each growing colony identified, 100 μL of fresh growth medium was added to each well and the cells were grown undisturbed in a 37° C. incubator under 5% carbon dioxide for two weeks. After two additional weeks of growth, the growing single colonies were trypsin-treated and transferred to a new 96-well plate for continued growth. Once colonies grew to about 1,000 cells, based on visual inspection, the cells were trypsin-treated and each cell-suspension was transferred into a new well from a 24-well Collagen IV-coated plate. The cells were grown in a 37° C. incubator under 5% carbon dioxide with fresh growth medium being replenished every 2-3 days, if needed. The cells were grown until the culture reached approximately 60% confluence or greater, at which point the cells were trypsin-treated and each cell-suspension was transferred into a 25 cm 2  Collagen IV-coated flask. The cells were grown in a 37° C. incubator under 5% carbon dioxide with fresh growth medium being replenished every 2-3 days, if needed. Once the cells in the flask reached 70-80% confluence, they were frozen and stored in liquid nitrogen until the clonal cell lines were tested to determine their susceptibility to BoNT/A intoxication. Of the 1,824 colony isolates initially setup from both screens, 130 clonal cell lines were selected based on viability and growth criteria and expanded for subsequent screening procedures. 
     2. Primary Screen for BoNT/A Intoxication Susceptibility of Cells from a Clonal Cell Line Using a BoNT/A Complex. 
     One way to determine whether cells from a clonal cell line were susceptible to BoNT/A intoxication was to conduct a primary screen using a CELLTITER-GLO® luminescent cell viability assay (Promega, Madison, Wis.) for normalizing the cell number in each well and an immuno-based method for determining BoNT/A activity as described in Ester Fernandez-Salas, et al., Immuno-Based Botulinum Toxin Serotype A Activity Assays, U.S. patent application Ser. No. 12/403,531, which is hereby incorporated by reference in its entirety. Two separate 96-well plates were set up, one for the BoNT/A activity assay and the other for the cell viability assay. 
     To conduct the BoNT/A activity assay, a lysate was prepared from cells treated with BoNT/A by plating cells from each isolated clonal cell line into a well from a poly-D-lysine 96-well plate (BD Biosciences, Bedford, Mass.). The wells contained 0.1 mL of a serum-free medium comprising Minimum Essential Medium, 2 mM GlutaMAX™ I with Earle&#39;s salts, 1×B27 supplement, 1×N2 supplement, 0.1 mM Non-Essential Amino Acids, 10 mM HEPES and 25 pg/mL GT1b (302-011-M005, Alexis Biochemicals, San Diego, Calif.). These cells were incubated in a 37° C. incubator under 5% carbon dioxide until the cells differentiated, as assessed by standard and routine morphological criteria, such as growth arrest and neurite extension (approximately 3 days). The media from the differentiated cells was aspirated from each well and replaced with fresh media containing 1 nM of a BoNT/A complex. After a 24 hrs incubation, the cells were washed by aspirating the growth media and rinsing each well with 200 μL of 1×PBS. To harvest the cells, 1×PBS was aspirated, the cells lysed by adding 30 μl of Lysis Buffer comprising 20 mM Tris-HCl (pH 7.5), 150 mM NaCl, 1 mM EDTA, 1 mM EGTA, 1% Triton X-100 to each well, and the plate incubated on a shaker rotating at 500 rpm for 30 minutes at 4° C. The plate was centrifuged at 4000 rpm for 20 minutes at 4° C. to pellet cellular debris and the supernatant was transferred to a capture antibody coated 96-well plate to perform the detection step. 
     To prepare an α-SNAP-25 capture antibody solution, the α-SNAP-25 mouse monoclonal antibody contained in the ascites from hybridoma cell line 2E2A6 (Example VII) was purified using a standard Protein A purification protocol. 
     To prepare an α-SNAP-25 detection antibody solution, α-SNAP-25 rabbit polyclonal antibody S9684 (Sigma, St. Louis, Mo.) was conjugated to Ruthenium(II)-tris-bipyridine-(4-methylsulfonate) NHS ester labeling reagent (Meso Scale Discovery, Gaithersburg, Md.) according to the manufacturer&#39;s instructions (Meso Scale Discovery, Gaithersburg, Md.). The conjugation reaction was performed by adding 30 μL of distilled water reconstituted MSD SULFO-TAG™ stock solution to 200 μL of 2 mg/mL α-SNAP-25 polyclonal antibodies and incubating the reaction at room temperature for 2 hours in the dark. The labeled antibodies were purified using a standard spin column protocol and the protein concentration determined using a standard colorimetric protein assay. The absorbance of the α-SNAP-25 antibody/MSD SULFO-TAG™ conjugate was measured at 455 nm using a spectrophotometer to determine the concentration in moles per liter. The detection antibody solution was stored at 4° C. until needed. 
     To prepare an α-SNAP-25 solid phase support comprising an α-SNAP-25 capture antibody, approximately 5 μL of the appropriate α-SNAP-25 monoclonal antibody solution (20 μg/mL in 1×PBS) is added to each well of a 96-well MSD High Bind plate and the solution is allowed to air dry in a biological safety cabinet for 2-3 hours in order to liquid evaporate the solution. The capture antibody-bound wells were sealed and stored at 4° C. until needed. 
     To detect the presence of a cleaved SNAP-25 product by ECL sandwich ELISA, the wells from an α-SNAP-25 solid phase support were then blocked by adding 150 μL of Blocking Buffer comprising 2% Amersham Blocking Reagent (GE Life Sciences, Piscataway, N.J.) and 10% goat serum (VWR, West Chester, Pa.) at room temperature for 2 hours. The Blocking Buffer was aspirated, 25 μL of a lysate from cells treated with BoNT/A was added to each well and the plates were incubated at 4° C. for overnight. Plate wells were washed three times by aspirating the cell lysate and rinsing each well three times with 200 μL 1×PBS, 0.1% TWEEN-20® (polyoxyethylene (20) sorbitan monolaureate). After washing, 25 μl of 5 μg/mL α-SNAP-25 detection antibody solution comprising 2% Amersham Blocking Reagent in 1×PBS, 0.1% TWEEN-20® (polyoxyethylene (20) sorbitan monolaureate) was added to each well, sealed, and incubated at room temperature for 1 hour with shaking. After α-SNAP-25 detection antibody incubation, the wells were washed three times with 200 μL 1×PBS, 0.1% TWEEN-20® (polyoxyethylene (20) sorbitan monolaureate). After washing 150 μL of 1× Read Buffer (Meso Scale Discovery, Gaithersburg, Md.) was added to each well and the plates were read using a SECTOR™ Imager 6000 Image Reader (Meso Scale Discovery, Gaithersburg, Md.). The raw data was collected using the ECL imager. 
     To conduct the luminescent cell viability assay, cells from each isolated clonal cell line were plated and differentiated as described above. The media from the differentiated cells was aspirated from each well and replaced with 100 μl of the reagent mixture comprising the CELLTITER-GLO® substrate and CELLTITER-GLO® buffer according to the manufacturer&#39;s instructions. The plate was then protected from light and mixed for two minutes on an orbital shaker. The solution from the 96-well cell plate with clear bottom was transferred to a white luminometer plate and after 10 minutes incubation was read on the luminometer. 
     These results indicated that the cell viability readings ranged from 9,838 to 10,423,188 and BoNT/A activity signals ranged from 84 to 27,242 (Table 1). In addition, a ratio of BoNT/A activity over cell viability was calculated to normalize the data, although there was not always a 1:1 ratio of viability and activity. Seven clonal cell lines exhibited activity/viability ratios of about 0.2×10 −2  or greater: H1, A7, A11, F10, A9, A10, and C11 (Table 1). Nine clonal cell lines exhibited activity/viability ratios of about 0.125×10 −2  to about 0.150×10 −2 : H3, H8, E11, H10, A6, C5, C12, D11, and B5 (Table 1). Two cell lines exhibited activity/viability ratios of about 0.100×10 −2 : D7 and B10 (Table 1). Based on these activity/viability ratios in conjunction with the cell viability and BoNT/A activity signal measurements, these 18 clonal cell lines were selected for further testing by conducting a secondary screen using a BoNT/A activity assay in order to generate a dose-response curve to BoNT/A.

     To conduct BoNT/A activity assay in order to generate a dose-response curve to BoNT/A, cells from each isolated clonal cell line were seeded in a poly-D-lysine 96-well plate and differentiated as described above. Of the top 18 clonal cell lines selected for further testing, only 8 remained viable, the remaining 10 clonal cell lines failed to regrow and were lost. The media from the differentiated cells was aspirated from each well and replaced with fresh media containing either 0 (untreated sample), 0.03 pM, 0.1 pM, 0.3 pM, 0.9 pM, 2.8 pM, 8.3 pM, and 25 pM of a BoNT/A complex. After a 24 hrs treatment, the cells were washed, incubated for an additional two days in serum-free medium without toxin to allow for the cleavage of the SNAP-25 substrate, and harvested as described above. The supernatant was transferred to a capture antibody coated 96-well plate to perform the detection step. 
     The α-SNAP-25 capture antibody solution, the α-SNAP-25 detection antibody solution, and the α-SNAP-25 solid phase support were prepared as described above. Detection of the presence of cleaved SNAP-25 product by ECL sandwich ELISA analysis was performed as described above. The raw data obtained from the ECL imager was then transferred to SigmaPlot v. 9.0 and a 4-parameter logistics fit was used to define the dose-response curves. There were no constraints used for the 4-parameter logistic function when plotting the data. Graphical reports were generated using the following analysis: R2 (correlation coefficient), a (Max for data set), b (hillslope), and X0±SE (E050 value±standard error). 
     These results indicate that of the 8 clonal cell lines tested, only two were more susceptible to BoNT/A intoxication when compared to cells comprising the parental SiMa cell line (Table 2). For example, cells comprising the parental SiMa cell line exhibited an EC 50  activity for BoNT/A of 2.20 pM, whereas cells comprising the H1 and A10 cell lines exhibited an EC 50  activity for BoNT/A of 1.76 pM or less. Conversely, cells comprising the H10 and D11 cell line exhibited an EC 50  activity for BoNT/A that was higher than that observed for cells comprising the parental SiMa cell line, but less than 5.0 pM. It should be noted that any clonal cell line exhibiting an EC 50  activity for BoNT/A that is 5.0 pM or less (100 U/mL or less) is useful for an immuno-based method for determining BoNT/A activity described in Ester Fernandez-Salas, et al., Immuno-Based Botulinum Toxin Serotype A Activity Assays, U.S. patent application Ser. No. 12/403,531.

3. Primary Screen for BoNT/A Intoxication Susceptibility of Cells from a Clonal Cell Line Using a Formulated BoNT/A Pharmaceutical Product.
 
     Another way to determine whether cells from a clonal cell line were susceptibility to BoNT/A intoxication was to conduct a primary screen by generating a dose-response curve to BoNT/A and calculate the EC 50  value using an immuno-based method for determining BoNT/A activity as described in Ester Fernandez-Salas, et al., Immuno-Based Botulinum Toxin Serotype A Activity Assays, U.S. patent application Ser. No. 12/403,531, which is hereby incorporated by reference in its entirety. 
     Initially six of 35 clonal cell line isolates were examined using a full dose response to BoNT/A. To prepare a lysate from cells treated with BoNT/A, cells from six clonal cell line were seeded in a poly-D-lysine 96-well plate and differentiated as described above in Section 2 except that the serum-free medium comprised 60 μg/mL GT1b. The clonal cell lines used were 3D8, YB8, 1D4, 2D6, 1E11, 2F5. The H1 and H10 clonal cell lines identified above, along with the parental SiMa cell line, were used as references to identify cell lines highly susceptible to BoNT/A intoxication. The media from the differentiated cells was aspirated from each well and replaced with fresh media containing either 0 (untreated sample), 0.98 U/mL, 1.9 U/mL, 3.91 U/mL, 7.81 U/mL, 15.6 U/mL, 31.3 U/mL, 62.5 U/mL, 125 U/mL, 250 U/mL, or 500 U/mL of a formulated BoNT/A pharmaceutical product. After a 24 hrs treatment, the cells were washed, incubated for an additional two days in serum-free medium without toxin to allow for the cleavage of the SNAP-25 substrate. To harvest the cells, 1×PBS was aspirated, the cells lysed by adding 30 μl of Lysis Buffer comprising 20 mM Tris-HCl (pH 7.5), 150 mM NaCl, 1 mM EDTA, 1 mM EGTA, 1% Triton X-100 to each well, and the plate incubated on a shaker rotating at 500 rpm for 30 minutes at 4° C. The plate was centrifuged at 4000 rpm for 20 minutes at 4° C. to pellet cellular debris. The protein concentration was determined using standard methods. The supernatant was transferred to a capture antibody coated 96-well plate to perform the detection step of the immuno-based method. 
     The α-SNAP-25 capture antibody solution, the α-SNAP-25 detection antibody solution, and the α-SNAP-25 solid phase support were prepared as described above in Section 2. Detection of the presence of SNAP-25 cleavage product by ECL sandwich ELISA analysis was performed, collected data was analyzed and the EC 50  calculated as described above in Section 2, except that SigmaPlot v. 10 was used. 
     These results show that clonal cell line H1 comprises cells that are more susceptible to BoNT/A than the parental SIMa cell line (Table 3). In addition, results indicate that although clonal cell lines H10, 1 D4, 1E1 1, 2D6, 2F5, 3D8, and YB8 all comprise cells that are less susceptible to BoNT/A than the parental SiMa cell line, all have an EC 50  of BoNT/A activity that is below 30 U/mL (Table 3). It should be noted that any clonal cell line exhibiting an EC 50  activity for BoNT/A that is 100 U/mL or less (5.0 pM or less) is useful for an immuno-based method for determining BoNT/A activity described in Ester Fernandez-Salas, et al., Immuno-Based Botulinum Toxin Serotype A Activity Assays, U.S. patent application Ser. No. 12/403,531.

     This initial primary screen using a dose-response curve with the 10 different BoNT/A concentrations identified three concentrations that were useful for a shortened assay using 3 different BoNT/A concentrations, with one concentration being slightly higher than the lower asymptote (8 U/mL), one concentration near the EC 50  (25 U/mL), and one concentration representing about 80% of the upper asymptote (80 U/mL). In these subsequent primary screens the remaining 29 clonal cell line isolates were tested as described above except that the cells were treated with either 0 (untreated sample), 8 U/mL, 25 U/mL, or 80 U/mL of a formulated BoNT/A pharmaceutical product. The clonal cell lines tested were 1E3, 2B9, 2D2, 2E4, 3B8, 3D5, 3G10, 4B5, 4C8, 4D3, 5C10, 5F3, AC9, AF4, BB3, BF10, BE3, BF8, CC11, CD6, CE6, CG8, CG10, DC4, DD10, DE7, DF5, YB7, and YF5. In addition, the parental SiMa was used as positive control. 
     These results show that clonal cell lines 2E4, 3B8, 3D5, 5F3, AF4, BB3, BB10, and DC4 all comprise cells that are more susceptible to BoNT/A than the parental SiMa cell line (Table 4). In addition, these results indicate that clonal cell lines 1E3, 2B9, 3G10, 4B5, 4C8, AC9, BE3, BF8, CC11, CD6, CE6, CG8, CG10, DD10, DE7, and YF5 all comprise cells that are of similar susceptibility to BoNT/A to that of the parental SiMa cell line (Table 4). Lastly, these results reveal that clonal cell lines 2D2, 4D3, 5C10, DF5, and YB7 all comprise cells that are less susceptible to BoNT/A than the parental SiMa cell line (Table 4).

     Example II 
     Stability Analysis of Clonal Cell Lines 
     The following example illustrates how to characterize the stability of cells from an established clonal cell line that are susceptible to BoNT/A intoxication or have neurotoxin uptake capacity. 
     During characterization of the SiMa cell line, it was determined that the parental SiMa cell line became unstable in terms of a significant loss of sensitivity to BoNT/A. For example, prior to passage 13, cells comprising the parental SiMa cell line routinely exhibited an EC 50  for BoNT/A activity that was under 5.0 pM. However, after passages about 14 to about 20 passages, cells comprising the parental SiMa cell exhibited an EC 50  for BoNT/A activity that was routinely over 25.0 pM. One reason for this dramatic reduction in the EC 50  value may be because the SiMa cell line is heterogeneous in nature since it comprises at least five different cell types. Over time, one of these cell types could overtake the culture to the exclusion of the other four. If the overtaking cell type was less susceptible to BoNT/A intoxication, or not susceptible at all, then as this cell type became the dominant one in the cell line the EC 50  for BoNT/A activity in this overtaken SiMa cell line would decrease. Thus, because the established clonal cell lines were derived from only one of these cell types, then it follows that the clonal cell line would exhibit greater stability in terms of maintaining an EC 50  for BoNT/A activity that was routinely under 5.0 pM. 
     To determine whether the cells from the established clonal cell lines showed increased stability relative to the cells comprising the parental SIMa cell line, the EC 50  for BoNT/A activity was determined for clonal cell lines BB10, H1, H10, and the parental SiMa cell line at different passage numbers using an immuno-based method for determining BoNT/A activity. The media from the differentiated cells was aspirated from each well and replaced with fresh media containing either 0 (untreated sample), 0.98 U/mL, 1.9 U/mL, 3.91 U/mL, 7.81 U/mL, 15.6 U/mL, 31.3 U/mL, 62.5 U/mL, 125 U/mL, 250 U/mL, or 500 U/mL of a formulated BoNT/A pharmaceutical product. After a 24 hrs treatment, the cells were washed, incubated for an additional two days in serum-free medium without toxin to allow for the cleavage of the SNAP-25 substrate, and harvested as described above. The supernatant was transferred to a capture antibody coated 96-well plate to perform the detection step. 
     Similarly, the preparation of the α-SNAP-25 capture antibody solution, α-SNAP-25 detection antibody solution, and the solid phase support comprising an α-SNAP-25 capture antibody were as described in Section 3. Lastly, detection of the presence of SNAP-25 cleavage product by ECL sandwich ELISA was performed, collected data was analyzed, and the EC 50  calculated as described above in Section 2, except that PLA v. 2 was used for the 4-parameter logistics fit. 
     The results from this stability experiments indicated that BB10, H1 and H10 cell lines all exhibited increase stability as compared to the parental SiMa cell line. For example, where cells from the parental SiMa cell line exhibited an EC 50  for BoNT/A activity that was over 500 U/mL (or 25 pM) after passages about 14 to about 20 passages, cells comprising the BB10, H1 and H10 cell lines all exhibited an EC 50  for BoNT/A activity that was below 10 U/mL (or 0.5 pM) after passage about 30. 
     Example III 
     Gene Expression Profile of Cell Lines Comprising Cells Susceptible to BoNT/A Intoxication 
     The following example illustrates how to characterize cells from an established clonal cell line that are susceptible to BoNT/A intoxication or have neurotoxin uptake capacity by gene expression profiling. 
     To determine the changes in genome-wide gene transcription levels in cells susceptible to BoNT/A intoxication, gene expression analysis was performed on cells from H1, BB10, 2D6 and the parental SiMa cell line, in both differentiated and undifferentiated states using GENECHIP® U133 Plus 2 microarray technology (Affymetrix, Inc., Santa Clara, Calif.) according to the manufacturer&#39;s instructions, see, e.g.,  GENECHIP® Expression Analysis Technical Manual,  702232, Rev. 2 (2006) which is hereby incorporated by reference in its entirety. 
     To prepare differentiated cells for these cell lines, a suitable density of cells from the H1, BB10, 2D6, and SiMa cell lines were seeded in separate T175 tissue culture flasks containing 50 mL of a serum-free medium comprising Enhanced Minimum Essential Medium, 10 mM HEPES, 1 mM sodium pyruvate, 0.1 mM Non-Essential Amino Acids, 1×B27 supplement, 1×N2 supplement, and 60 μg/mL GT1b (302-011-M005, Alexis Biochemicals, San Diego, Calif.). These cells were incubated in a 37° C. incubator under 5% carbon dioxide until the cells differentiated, as assessed by standard and routine morphological criteria, such as growth arrest and neurite extension, and attained 80% confluence (approximately 3 days). The cells were then washed with 50 mL of 1×PBS, trypsin-treated for 5 min at room temperature, and then 15 mL of growth medium was added to the flask to inactivate the trypsin. The cell suspension was transferred to a 50 mL tube and centrifuge at 200 RCF for 5 min at room temperature to pellet the cells. The cell pellet was washed once in 50 mL of 1×PBS, centrifuge at 200 RCF for 5 min at room temperature to pellet the cells, and the supernatant was removed. The cell pellet was quick frozen on dry ice and stored at −80° C. until needed. 
     To prepare undifferentiated cells for these cell lines, a suitable density of cells from the H1, BB10, 2D6, and SiMa cell lines were seeded in separate T175 tissue culture flasks containing 50 mL of growth medium comprising RPMI 1640, 10% fetal bovine serum, 10 mM HEPES, 1 mM sodium pyruvate, 0.1 mM Non-Essential Amino Acids, and 60 μg/mL GT1b. These cells were incubated in a 37° C. incubator under 5% carbon dioxide until the cells attained 80% confluence (approximately 3 days). The cells were then processed as described above and the cell pellet was quick frozen on dry ice and stored at −80° C. until needed. 
     To prepare total RNA, cells for each cell line were lysed and total RNA isolated and purified using a RNA isolation kit (QIAGEN, Valencia, Calif.) according to the manufacturer&#39;s protocols. DNA was digested using an on-column DNase I procedure (QIAGEN, Valencia, Calif.). RNA was quantified photospectrometrically at 260 nm and purity assessed by the A260A280 ratio using a spectrophotometer. RNA integrity was assessed using a Bioanalyser 2100 (Agilent Technologies, Inc., Santa Clara, Calif.). Extracted total RNA aliquots were snap-frozen in liquid nitrogen and stored at −80° C. 
     To prepare cDNA probes for the gene microarray chips, about 1-15 μg was reversed transcribed using a T7-Oligo(dT) promoter primer in the first strand cDNA synthesis reaction. Following RNase H-mediated second strand cDNA synthesis, the double-stranded cDNA was purified and served as a template for subsequent in vitro transcription reaction. The in vitro transcription reaction was carried out in the presence of T7 RNA polymerase and a biotinylated nucleotide analog/ribonucleotide mix for complementary RNA (cRNA) amplification and biotin labeling. The biotinylated cRNA targets were then cleaned up, fragmented, and hybridized to microchip expression arrays for 17 hours at 65° C. according to the manufacturer&#39;s instructions, see, e.g.,  GENECHIP® Expression Analysis Technical Manual,  702232, Rev. 2 (2006) which is hereby incorporated by reference in its entirety. To identify substantial treatment-related up- or down-regulated gene expression differences compared to control cell lines, greater than 1.5-fold differences (loge 0.58) were considered significant, and only those genes that displayed consistent changes in expression in the triplicate analysis were considered (Tables 5-12). 
     Expression profiling for cell lines H1, BB10 and 2D6 analyzed in the undifferentiated state revealed that 1,323 genes were identified as having their expression levels increase by 1.5-fold (loge 0.58) or more in the H1 and BB10 cell lines as compared to the gene expression levels obtained from the 2D6 cell line (Table 5).

     Example IV 
     Pathway Analysis of Gene Expression Profiles from Clonal Cell Lines 
     The following example illustrates how to characterize gene expression profiles from clonal cells from an established clonal cell line that are susceptible to BoNT/A intoxication or have neurotoxin uptake capacity in order to identify biological networks or pathways associated with BoNT/A intoxication. 
     An Ingenuity Pathway Analysis (IPA) Core Analysis (Ingenuity Systems Inc., Redwood City, Calif.) was performed to characterize the RNA expression phenotype of two independently derived BoNT/A very sensitive single clone cell lines, BB10 and H1, compared to a related but much less BoNT/A sensitive single clone cell line, 2D6. The analysis was done to identify the specific gene expression phenotype of a BoNT/A sensitive cell line. The result can also be used to predict and potentially identify proteins that function to enhance BoNT/A uptake. 
     An Ingenuity Pathway Analysis (IPA) Core Analysis was performed that identified biologically relevant networks to BoNT/A intoxication based on connectivity among the genes from an IPA library and the genes exhibiting significant changes as determined from the expression profiling discussed above. For this analysis, all genes that exhibited an increased or decrease in expression levels in the H1 and BB10 cell lines by 4-fold (loge 2.0) or more as compared to the expression level for these genes determined from the 2D6 cell line were used, in conjunction with, selected genes with known or suspected relevance to BoNT/A intoxication, hereafter referred to as the Profile genes. The significance of the association to a given network was measured and ranked by the ratio of the number of Profile genes that mapped to the specific network divided by the total number of genes that map to that network. Fisher&#39;s exact test was used to calculate p-scores, which represent the association between the Profile genes and the network, and based on the p-scores the genes from the Profile genes were used to rank the networks. The p-scores were derived from p-values. If there are n genes in the network and f of them are Profile genes, then the p-value is the probability of finding f or more Profile genes in a set of n genes randomly selected from the Global Molecular Network. Since significant p-values are quite low (e.g., 1×10 −8 ), a p-score was defined as the component of the p-value; p-score=−log 10 (p-value). The identified networks were overlaid with differentially expressed genes which had more than 1.5-fold differential expression and a p-value ≤0.001 either before or after differentiation. 
     Using IPA Core Analysis the differentially expressed Profile genes were connected to 26 Networks. Nineteen of these included 10 or more Profile genes (Table 13). Among these nineteen networks three overall networks groups, named A, B and C were identified (Table 13). Within the networks in these three groups there were overlapping genes and the expression for more than three genes was increased after differentiation. Group A genes include the FGFR2 receptor which has been shown to function in the BoNT/A intoxication process as a receptor for BoNT/A and are as follows: genes exhibiting a 1.5-fold or more decrease in expression levels in the H1 and BB10 cell lines as compared to their expression in cells from the 2D6 cell line, ANXA2, AQP1, ARHGAP9, CDH10, CDKN2A, CHPT1, CNTN2, ERAP1, and RGS11; genes exhibiting a 1.5-fold or more increase in expression levels in the H1 and BB10 cell lines as compared to their expression in cells from the 2D6 cell line, ADAMTS9, ATAD2, C11ORF82, CDC45L, CNTN1, CNTN4, Cyclin A, Cyclin E, E2F1, E2F2, E2F7, ELOVL7, EME1, FGFR, FGFR2, KIAA1524, MELK, MYBL1, MYBL2, NDC80, NDN, ORC1L, PLS3, PRIMA1, RAD54L, RBL1, RBPMS, RRM2, S1PR3, SCLY, SLCIA3, SPC24, SPC25, ST8SIA4, TFDP1, TFP12, TK1, TMEM35, TTK, TWIST1, TYMS, TYK, and ZWINT.

     Pathway Analysis of Gene Expression Profiles from Clonal Cell Lines 
     The following example illustrates how to characterize gene expression profiles from clonal cells from an established clonal cell line that are susceptible to BoNT/A intoxication or have neurotoxin uptake capacity in order to identify biological networks or pathways associated with BoNT/A intoxication. 
     Computer analysis was performed to characterize the RNA expression phenotype of two independently derived single clone cell lines, BB10 and H1, very sensitive to BoNT/A activity and a single clone cell line, 2D6, that was less sensitive BoNT/A activity. The results are useful in identifying clonal cell lines selected from the SiMa parental cell line that are useful to practice the methods disclosed in the present specification. 
     To identify the specific gene expression phenotype associated with a BoNT/A sensitive cell line, the data was analyzed using JMP Genomic (SAS Institute Inc., Cary, N.C.). To perform a JMP Genomics analysis, the RNA expression data was imported to JMP Genomics by creating two SAS files, designated “data” and “Experiment design.” A basic expression workflow was performed, including a variance analysis and one-way analysis of variance (one-way ANOVA) to identify differences in mean expression values. The variance analysis was used to identify differences between the cell lines and the differentiation state of each cell line (differentiated or non-differentiated). The expression values of all four cell lines were compared pair wise, independent of differentiation and genes that were 4-fold over-expressed in the H1 cell line as compared to the 2D6 cell line, in the BB10 cell line as compared to the 2D6 cell line, and in SiMa parental cell line (PA) compared to the 2D6 cell line. The variance analysis treats all factors in the study as random effects, to find out what their contribution is to the proportion of variance explained (total variance=100%). About half of the variance, 46.9% was assigned to differences among the different cell types, while 26% was assigned to differences before and after differentiation. Only 4.6% of the variance was assigned to differences among differentiated or non-differentiated cells types, meaning that the genes that were differentially expressed after differentiation were similar for all cell types examined, suggesting that the difference in BoNT/A sensitivity among the cell lines is independent of differentiation state. As such, the focus was placed on genes that are different among the different cells types irrespective of differentiation. 
     Based on the results from the variance analysis, the expression values of all cell lines were compared pair wise, independent of differentiation ( FIG. 2 ). Only gene probes that were 4-fold over-expressed in the H1 cell line as compared to the 2D6 cell line, and in the BB10 cell line as compared to the 2D6 cell line are shown. The gene probes were plotted as expression value (Log 2 ) on the x-axis and p-value (−log 10 (p-value)) on the y-axis. The red dashed line marks the 95% confidence interval. The genes probes that were ≥4-fold over-expressed in the H1 cell line as compared to the 2D6 cell line ( FIG. 2A ), and the BB10 cell line as compared to the 2D6 cell line ( FIG. 2B ), were also to a large extend among the genes that were over-expressed in the BB10 cell line as compared to the SiMa parental cell line (PA,  FIG. 2C ), in the H1 cell line as compared to the SiMa parental cell line ( FIG. 2D ), and in the SiMa parental cell line as compared to the 2D6 cell line ( FIG. 2E ). These data suggest that BoNT/A sensitivity was related to a gradual increase in expression of these genes. Based on this finding, the number of gene probes was further narrowed down to 119 by including only gene probes that were also over-expressed in the SiMa parental cell line compared to the 2D6 cell line, rationalizing that gene probes that were differential expressed across one more cell line would be even more likely to be important for BoNT/A sensitivity. As such, the JMP Genomic analysis resulted in the identification of 119 gene probes, designated the JMP probe set. 
     The JMP probe set was exported to Ingenuity Pathway Analysis (IPA) Core Analysis (Ingenuity Systems Inc., Redwood City, Calif.) to further characterize the JMP probe set. Using this analysis, biologically relevant networks to BoNT/A intoxication were identified based on connectivity among the genes from an IPA library and the gene probes contained in the JMP probe set. The significance of the association to a given network was measured and ranked by the ratio of the number of gene probes from the JMP probe set that mapped to the specific network divided by the total number of genes that map to that network. Fisher&#39;s exact test was used to calculate p-scores, and based on the p-scores the genes from the JMP probe set were used to rank the networks. The p-scores were derived from p-values. If there are n genes in the network and f of them are gene probes from the JMP probe set, then the p-value is the probability of finding f or more gene probes from the JMP probe set in a set of n genes randomly selected from the Global Molecular Network. Since significant p-values are quite low (e.g., 1×10 −8 ), a p-score was defined as the component of the p-value; p-score=−log 10 (p-value). The identified networks were overlaid with differentially expressed genes which had more than 1.5-fold differential expression and a p-value ≤0.001 either before or after differentiation. Using IPA Core Analysis, 111 of the 119 gene probes from the JMP probe set were mapped to networks. The eight unmapped probes most likely represent either a probe with an outdated nomenclature or one representing a gene without a known gene product. The 111 gene probes corresponded to 79 genes that were greater than 4.0-fold differentially expressed in the H1 and BB10 cell lines when compared to the 2D6 cell line and that were also greater than 4.0-fold differentially expressed in the SiMa parental cell lines when compared to the 2D6 cell line, when the p-value cut off was set to 0.05 (Table 14).

                 The log ratio represent log 2  values where 0.585 is log 2 (1.5) which is a 1.5-fold difference, 1 is log 2 (2) which is a 2-fold difference, 1.584 is log 2 (3) which is a 3-fold difference, 2 is log 2 (4) which is a 4-fold difference, 2.321 is log 2 (5) which is a 5-fold difference, 2.584 is log 2 (6) which is a 6-fold difference, 2.807 is log 2 (7) which is a 7-fold difference, 3 is log 2 (8) which is a 8-fold difference, 3.169 is log 2 (9) which is a 9-fold difference, and 3.321 is log 2 (10) which is a 10-fold difference. 
               
            
           
         
       
     
     Using IPA Core Analysis, 73 of the 79 genes were mapped to 5 different protein networks (Table 15). Based on overlapping gene mapping, 73 of the 79 genes that were up-regulated could be associated with two major protein network groups, named A and B (Table 15). Networks 1, 2 and 5 belong to Group A, and Networks 3 and 4 belong to Group B. Similarly, all down-regulated genes were all associated with one network, named C (Table 15). 
     Group A genes include the FGFR2 receptor which has been shown to function in the BoNT/A intoxication process as a receptor for BoNT/A and are as follows: genes exhibiting a 1.5-fold or more increase in expression levels in the H1 and BB10 cell lines as compared to their expression in cells from the 2D6 cell line, ADAMTS9, ARHGAP24, ARHGEF3, ASCL1, BARD1, CD9, CDK2, CSRP2, CTSL2, DIAPH3, DOK5, DYNLT3, EMILIN2, ETV1, FBLN1, FGFR2, GNAI1, GNB4, GNG11, GNG12, HGF, KITLG, LPAR1, MCM10, MSN, PAG1, PEG3, PLK2, POLA2, PPP1R3C, PTPRK, RAB32, SDC2, SLC43A3, SLC7A2, SMC6, SPARC, SPC25, ST8SIA4, TCF7L1, TFPI2, TMEM35, TNFAIP8, TPTE, TRIP10, and TWIST1. 
     Group B genes are as follows: genes exhibiting a 1.5-fold or more increase in expression levels in the H1 and BB10 cell lines as compared to their expression in cells from the 2D6 cell line, ACOT9, BASP1, C11ORF75, CCDC109B, CDCA7L, CLSTN2, CNTN1, CUGBP2, DEPDC1, DPYD, FAM101B, FNDC5, GTSE1, MAOA, MINA, MYO6, MYRIP, PLK2, PRLHR, PVRL3, RBPMS, SGOL2, SMC2, TFP12, TMEM178, and ZNF521. 
     Group C genes are as follows: genes exhibiting a 1.5-fold or more decrease in expression levels in the H1 and BB10 cell lines as compared to their expression in cells from the 2D6 cell line, ANK2, CPNE8, CREB5, IL17B, KIAA0125, LOC100289109, LOC144571, NPAS4, SLC1A2, SORCS1, THBS2, and/or ZNF814. 
     The remaining networks identified did not share common genes between any other network. Individually, however, genes exhibiting a 1.5-fold or more increase in expression levels in the H1 and BB10 cell lines as compared to their expression in cells from the 2D6 cell line were as follows: C3ORF70 (Network 6), MAB21L2 (Network 7), PRSS12 (Network 8), CENPL (Network 9), GPR177 (Network 10), and PTGR1 (Network 11).

     Computer analysis was performed as in Example V, except that the list of probes reflects genes that were greater than 1.5-fold differential expressed in the H1 and the BB10 cell lines when compared to both the 2D6 and SiMa parental cell lines. When the p-value cut off was set to 0.05, this analysis identified 439 gene probes that could be classified to 369 genes (Table 16).

     Computer analysis was performed as in Example V, except that the list of probes reflects genes that were greater than 1.5-fold differential expressed in the H1 cell line and the BB10 cell line when compared to both the 2D6 and SiMa parental cell lines, and also a greater than 1.5-fold differential expressed in the SiMa parental cell line when compared to the 2D6 cell line. When the p-value cut off was set to 0.05, this analysis identified 94 gene probes that could be classified to 70 genes (Table 17).

     Immuno-Based Method to Detect Picomolar Amounts of BoNT/A 
     The following example illustrates how to perform immuno-based methods of detecting BoNT/A activity that can detect picomolar amounts of the BoNT/A pharmaceutical product, such as, e.g., BOTOX® DYSPORT®/RELOXIN®, PURTOX®, XEOMIN®, NEURONOX®, or BTX-A. 
     1. Immuno-Based Method of Detecting BoNT/A Using ECL Sandwich ELISA. 
     To prepare a lysate from cells treated with a BoNT/A, approximately 150,000 cells from an established clonal cell line was plated into the wells of 96-well tissue culture poly-D-lysine plates containing 100 μL of a serum-free medium containing Minimum Essential Medium, 2 mM GlutaMAX™ I with Earle&#39;s salts, 1×B27 supplement, 1×N2 supplement, 0.1 mM Non-Essential Amino Acids, 10 mM HEPES and 60 μg/mL GT1b. The cell lines used were BB10, H1, and SiMa. These cells were incubated in a 37° C. incubator under 5% carbon dioxide until the cells differentiated, as assessed by standard and routine morphological criteria, such as growth arrest and neurite extension (approximately 3 days). The media from the differentiated cells was aspirated from each well and replaced with fresh media containing one of the following: 1) SiMa cell line, 0 (untreated), 0.98 U/mL, 1.9 U/mL, 3.91 U/mL, 7.81 U/mL, 15.6 U/mL, 31.3 U/mL, 62.5 U/mL, 125 U/mL, 250 U/mL, or 500 U/mL of a BoNT/A pharmaceutical product reconstituted in a sodium chloride free medium; 2) BB10, 0 (untreated), 0.49 U/mL, 0.98 U/mL, 1.9 U/mL, 3.91 U/mL, 7.81 U/mL, 15.6 U/mL, 31.3 U/mL, 62.5 U/mL, 125 U/mL, 250 U/mL; 3) H1, 0 (untreated), 0.3 U/mL, 1 U/mL, 3 U/mL, 9 U/mL, 28 U/mL, 83 U/mL, and 250 U/mL. Because the BoNT/A pharmaceutical product contains sodium chloride, its addition to the culture medium resulted in a hypertonic media that was detrimental to cell viability. To circumvent the hypertonicity issue, 200 μL of MEM media made without sodium chloride was used to reconstitute the BoNT/A pharmaceutical product giving a final concentration of 25 pM BoNT/A (500 U/mL). The matrix was kept constant for all concentrations along the dose-response curve by adding sodium chloride in the media used to make the dilutions match the amount of excipients present at the highest concentration used (25 pM or 500 U/mL). After a 24 hr treatment, the cells were washed, and incubated for an additional two days without toxin. To harvest the cells, 1×PBS was aspirated, the cells lysed by adding 75 μL of Lysis Buffer comprising 50 mM HEPES, 150 mM NaCl, 1.5 mM MgCl 2 , 1 mM EGTA, 1% Triton X-100 to each well, and the plate incubated on a shaker rotating at 500 rpm for 30 minutes at 4° C. The plate was centrifuged at 4000 rpm for 20 minutes at 4° C. to pellet cellular debris and the supernatant was transferred to a capture antibody coated 96-well plate to perform the detection step. 
     To prepare the α-SNAP-25 capture antibody solution, the α-SNAP-25 monoclonal antibody contained in the ascites from hybridoma cell line 2E2A6 (Example VII) was purified using a standard Protein A purification protocol. To prepare the α-SNAP-25 detection antibody solution, α-SNAP-25 rabbit polyclonal antibody S9684 (Sigma, St. Louis, Mo.) was conjugated to Ruthenium(II)-tris-bipyridine-(4-methylsulfonate) NHS ester labeling reagent (Meso Scale Discovery, Gaithersburg, Md.) according to the manufacturer&#39;s instructions (Meso Scale Discovery, Gaithersburg, Md.). The conjugation reaction was performed by adding 30 μL of distilled water reconstituted MSD SULFO-TAG™ stock solution to 200 μL of 2 mg/mL α-SNAP-25 polyclonal antibodies and incubating the reaction at room temperature for 2 hours in the dark. The labeled antibodies were purified using a standard spin column protocol and the protein concentration determined using a standard colorimetric protein assay. The absorbance of the α-SNAP-25 antibody/MSD SULFO-TAG™ conjugate was measured at 455 nm using a spectrophotometer to determine the concentration in moles per liter. The detection antibody solution was stored at 4° C. until needed. 
     To prepare the solid phase support comprising the capture antibody that is specific for a SNAP-25 cleaved product, approximately 1 μL of α-SNAP-25 monoclonal antibody 2E2A6 solution (45 μg/mL in 1×PBS, 750 μg/mL of BSA) was added to each well of a 96-well MSD High Bind plate (Meso Scale Discovery, Gaithersburg, Md.) and the solution is allowed to air dry in a biological safety cabinet for 2-3 hours in order to liquid evaporate the solution, and then the plates were sealed and stored at 4° C. until needed. The dried capture antibody-bound wells were then blocked by adding 150 μL of Blocking Buffer comprising 1×PBS, 0.05% Tween-20, 2% ECL Blocking reagent (GE Healthcare-Amersham), and 1% goat serum (Rockland Immunochemicals, Gilbertsville, Pa.) at room temperature for 2 hours with rotation at 600 rpm. 
     To detect the presence of a SNAP-25 cleavage product by ECL sandwich ELISA analysis, the Blocking Buffer from plates was aspirated, 25 μL of a lysate from cells treated with BoNT/A was added to each well and the plates were incubated at 4° C. for overnight. Plate wells were washed three times by aspirating the cell lysate and rinsing each well three times with 200 μL 1×PBS, 0.1% TWEEN-20® (polyoxyethylene (20) sorbitan monolaureate). After washing, 25 μl of 5 μg/mL α-SNAP-25 detection antibody solution comprising 2% Amersham Blocking Reagent in 1×PBS, 0.1% TWEEN-20® (polyoxyethylene (20) sorbitan monolaureate) was added to each well, the plate was sealed, and the sealed plate was incubated at room temperature for 1 hour with shaking. After α-SNAP-25 detection antibody incubation, the wells were washed three times with 250 μL 1×PBS, 0.1% TWEEN-20® (polyoxyethylene (20) sorbitan monolaureate). After washing 150 μL of 1× Read Buffer (Meso Scale Discovery, Gaithersburg, Md.) was added to each well and the plates were read using a SECTOR™ Imager 6000 Image Reader (Meso Scale Discovery, Gaithersburg, Md.). The raw data was then transferred to SigmaPlot v 10.0 and a 4-parameter logistics fit was used to define the dose-response curves. There were no constraints used for the 4-parameter logistic function when plotting the data. Graphical reports were generated using the following analysis: R2 (correlation coefficient), a (Max for data set), b (hillslope), and X0±SE (EC 50  value±standard error). 
     These results indicated that on average the cells comprising the BB10 and H1 clonal cell lines were more susceptible to BoNT/A intoxication as compared to cells comprising the parental SiMa cell line. Cells from a BB10 cell line exhibited an EC 50  for BoNT/A activity of 7 U/mL, cells from a H1 cell line exhibited an EC 50  for BoNT/A activity of 8 U/mL, and cells from the parental SiMa cell line exhibited an EC 50  for BoNT/A activity of 13 U/mL. This method can also be performed in a multiplex fashion as described in Ester Fernandez-Salas, et al., Immuno-Based Botulinum Toxin Serotype A Activity Assays, U.S. patent application Ser. No. 12/403,531, which is hereby incorporated by reference in its entirety. 
     Example VII 
     Transfection of BoNT/A Receptor DNA into Sensitive Clonal Cell Lines Further Improves Sensitivity of the Clonal Cell Line for BoNT/A 
     The following example illustrates how to introduce a polynucleotide molecule encoding a BoNT/A receptor into cells from a clonal cell line to further improve susceptibility to BoNT/A intoxication or improve BoNT/A uptake capacity. 
     To introduce an exogenous BoNT/A receptor into cells comprising an established clonal cell line, a mammalian expression construct comprising a polynucleotide molecule of SEQ ID NO: 139 encoding the FGFR3 of SEQ ID NO: 25, was transfected into cells from a H1 clonal cell line by a cationic lipid method. A suitable density (about 5×10 6  cells) of cells from an established clonal cell line are plated in a 100 mm tissue culture dish containing 5 mL of complete culture media and grown in a 37° C. incubator under 5% carbon dioxide until the cells reached a density appropriate for transfection. A 3 mL transfection solution is prepared by adding 1.5 mL of OPTI-MEM® Reduced Serum Medium containing 60 μL of LIPOFECTAMINE® 2000 (Invitrogen, Carlsbad, Calif.) incubated at room temperature for 5 minutes to 1.5 mL of OPTI-MEM® Reduced Serum Medium containing 24 μg of an expression construct encoding the FGFR3 of SEQ ID NO: 25. This transfection mixture is incubated at room temperature for approximately 30 minutes. The complete media on the cells is replaced with the 3 mL transfection solution and the cells are incubated in a 37° C. incubator under 5% carbon dioxide for approximately 8 hours. Transfection media is replaced with 3 mL of fresh complete culture media and the cells are incubated in a 37° C. incubator under 5% carbon dioxide for approximately 24 hours. Media is replaced with 3 mL of fresh complete culture media containing approximately 1 mM G418 (Invitrogen, Carlsbad, Calif.) for selection of transfected cells. Cells are incubated in a 37° C. incubator under 5% carbon dioxide for approximately 1 week, the old media is replaced with fresh complete culture media containing 0.5 mM G418 and the cells are plated onto one 96-well collagen IV coated plate at a plating density of 0.5 cells per well. Cell growth and viability was monitored by microscopic examination and after about 3 weeks single clones appeared in about 20% of the wells. These clones were grown for an additional 2 weeks and then transferred to duplicate 24-well collagen IV coated plates, one to maintain the clonal cell line and the other to test for BoNT/A susceptibility. 
     To determine the susceptibility of the cells comprising the clonal cell lines overexpressing a BoNT/A receptor, a Western blot analysis was done to determine sensitivity and an ECL sandwich ELISA was done to determine an EC 50  value. A total of eight clones were tested for the FGFR3 stably transfected H1 cells. 
     To prepare a cell lysate for the Western blot analysis, cells from the clonal cell line were plated into two wells in a poly-D-lysine coated 96-well plate in serum-free medium containing Minimum Essential Medium, 2 mM GLUTAMAX™ I with Earle&#39;s salts, 1×B27 supplement, 1×N2 supplement, 0.1 mM Non-Essential Amino Acids, 10 mM HEPES and 25 μg/mL GT1b (Alexis Biochemicals, Lausen, Switzerland). These cells were incubated in a 37° C. incubator under 5% carbon dioxide until the cells differentiated, as assessed by standard and routine morphological criteria, such as growth arrest and neurite extension (approximately 3 days). The media from the differentiated cells was aspirated from each well and replaced with fresh media containing either 0 (untreated), 0.5 nM or 0.25 nM of a BoNT/A complex. After a 6 hr treatment, the cells were washed, and incubated for an additional 18 hr without toxin. After the incubation, the cells were washed by aspirating the growth media and rinsing each well with 200 μl of 1×PBS. To harvest the cells, the 1×PBS was aspirated, the cells were lysed by adding 40 μL of 2×SDS Loading Buffer and the plate was swirled for an even coating of Loading Buffer. The lysate was transferred to a new 96-well PCR plate (Axygen, Union City, Calif.) and the plate was heated to 95° C. for 5 min to complete cell lysis and denature proteins. 
     To detect for the presence of both uncleaved SNAP-25 substrate and cleaved SNAP-25 products, an aliquot from each harvested sample was analyzed by Western blot. In this analysis, a 12 μL aliquot of the harvested sample was separated by MOPS polyacrylamide gel electrophoresis using NUPAGE® Novex 12% Bis-Tris precast polyacrylamide gels (Invitrogen Inc., Carlsbad, Calif.) under denaturing, reducing conditions. Separated proteins were transferred from the gel onto nitrocellulose membranes (Bio-Rad Laboratories, Hercules, Calif.) by Western blotting using a “Transfer+4 cassettes &amp; Cooler” transfer chamber (GE Healthcare, Piscataway, N.J.). Membranes were blocked by incubating at room temperature for 1 hr with gentle agitation in a solution containing Tris-Buffered Saline (TBS) (25 mM 2-amino-2-hydroxymethyl-1,3-propanediol hydrochloric acid (Tris-HCl)(pH 7.4), 137 mM sodium chloride, 2.7 mM potassium chloride), 0.1% TWEEN-20® (polyoxyethylene (20) sorbitan monolaureate), 2% Bovine Serum Albumin (BSA), 5% nonfat dry milk. Blocked membranes were incubated at 4° C. for overnight in TBS, 0.1% TWEEN-20® (polyoxyethylene (20) sorbitan monolaureate), 2% BSA, and 5% nonfat dry milk containing a 1:5,000 dilution of α-SNAP-25 rabbit polyclonal antiserum S9684 (Sigma, St. Louis, Mo.) as the primary antibody. The α-SNAP-25 rabbit polyclonal antibodies can detect both the uncleaved SNAP-25 substrate and the SNAP-25 cleavage product, allowing for the assessment of overall SNAP-25 expression in each cell line and the percent of SNAP-25 cleaved after BoNT/A treatment as a parameter to assess the amount of BoNT/A uptake. Primary antibody probed blots were washed three times for 5 minutes each time in TBS, TWEEN-20® (polyoxyethylene (20) sorbitan monolaureate). Washed membranes were incubated at room temperature for 2 hours in TBS, 0.1% TWEEN-20® (polyoxyethylene (20) sorbitan monolaureate), 2% BSA, and 5% nonfat dry milk containing a 1:10,000 dilution of goat polyclonal anti-rabbit immunoglobulin G, heavy and light chains (IgG, H+L) antibody conjugated to horseradish peroxidase (Invitrogen, Inc., Carlsbad, Calif.) as a secondary antibody. Secondary antibody-probed blots were washed five times for 5 minutes each time in TBS, 0.1% TWEEN-20® (polyoxyethylene (20) sorbitan monolaureate). Signal detection of the labeled SNAP-25 products were visualized using the ECL Plus™ Western Blot Detection System (GE Healthcare, Amersham Biosciences, Piscataway, N.J.) and the membrane was imaged and the percent of cleaved SNAP-25 products quantified with a Typhoon 9410 Variable Mode Imager and Imager Analysis software (GE Healthcare, Amersham Biosciences, Piscataway, N.J.). The choice of pixel size (100 to 200 pixels) and PMT voltage settings (350 to 600, normally 400) depended on the individual blot. The volumes of the bands corresponding to either intact and cleaved SNAP-25 product were quantified using Image Quant TL and the total amount of SNAP-25 and the percentage of SNAP-25 cleaved were calculated based on the intensity of these two SNAP-25 bands. 
     Clone H1 1.4 had a high percentage of SNAP-25 cleavage and high levels of total SNAP25 and was selected for further testing. The selected clone was first grown on a 10 cm 2  dish and then in T175 flasks to ensure that enough cells were produced for both ECL sandwich ELISA assay and for freezing stocks. Frozen stocks were made with 1×10 6  cells and 1 mL of Recovery Cell Culture Freezing Media (GIBCO-Invitrogen, #12648-010 Freezing media). 
     To prepare a cell lysate for the ECL sandwich ELISA, approximately 50,000 cells from H1 clonal cell line and from H1 1.4 clonal cell line overexpressing FGFR3 were plated and differentiated as described above. The media from the differentiated cells was aspirated from each well and replaced with fresh media containing either (untreated), 0.27 pM, 0.82 pM, 2.47 pM, 7.4 pM, 22.2 pM, 66.6 pM, or 200 pM of a BoNT/A complex of a BoNT/A complex. After a 6 hr treatment, the cells were washed, and incubated overnight without toxin. After a 24 hr treatment, the cells were washed by aspirating the BoNT/A containing media and rinsing each well with 200 μL of 1×PBS. Washed cells were harvested by lysing in freshly prepared Triton X-100 Lysis Buffer (150 mM NaCl, 20 mM Tris-HCl (pH 7.5), 1 mM EDTA, 1 mM EGTA, 1% Triton X-100 plus protease inhibitors) at 4° C. for 30 minutes with constant agitation. Lysed cells were centrifuged at 4000 rpm for 20 min at 4° C. to pellet debris. 
     The α-SNAP-25 capture antibody solution, the α-SNAP-25 detection antibody solution, and the solid phase support comprising the capture antibody that is specific for a SNAP-25 cleaved product were prepared as described in Example V. To detect the presence of a cleaved SNAP-25 product by ECL sandwich ELISA, the plates were processed, and the data collected and analyzed, and the EC 50  calculated as described in Example VI. The EC 50  for H1 1.4 cells was estimated to about 1.7 pM, compared to an EC 50  about 8.7 pM for H1 cells indicating that the newly generated H1 1.4 cell line is about 5 times more sensitive than the H1 cell line for BoNT/A uptake (average of two independent experiments with similar results). The maximum signal for both cell lines was identical indicating similar efficacy towards SNAP25 cleavage. The increase in sensitivity is especially prominent at lower concentrations of BoNT/A, where the H1 1.4 cells are many times more sensitive to BoNT/A compared to H1 cells producing a very robust signal over background at the 0.27 pM concentration. Over-expression of FGFR3 was verified in a Western blot using α-FGFR3 antibodies sc-123 (Santa Cruz Biotechnologies, Santa Cruz, Calif.).

     Development of α-SNAP-25 Monoclonal Antibodies that Selectively Bind a SNAP-25 Epitope Having a Free Carboxyl-Terminus at the P 1  Residue of the BoNT/A Cleavage Site Scissile Bond 
     The following example illustrates how to make α-SNAP-25 monoclonal antibodies that can selectively bind to a SNAP-25 epitope having a carboxyl-terminus at the P 1  residue of the BoNT/A cleavage site scissile bond. 
     1. Generation of α-SNAP-25 Monoclonal Antibodies. 
     α-SNAP-25 monoclonal antibodies with higher binding affinity for a SNAP-25 cleavage product and/or α-SNAP-25 antibodies with a higher binding specificity for a SNAP-25 cleavage product were developed. In addition, because a permanent, stable and renewable source of α-SNAP-25 antibodies is preferable for an FDA-approved assay, screens to isolate monoclonal antibodies were undertaken. To develop monoclonal α-SNAP-25 antibodies the 13-residue peptide CDSNKTRIDEANQ COOH  (SEQ ID NO: 38) was designed as a SNAP-25 antigen having a carboxyl-terminus at the P 1  residue of the BoNT/A cleavage site scissile bond. This peptide comprises a flexible linker region and a N-terminal Cysteine residue for conjugation to KLH and amino acids 186-197 of human SNAP-25 (SEQ ID NO: 5) with a carboxylated C-terminal glutamine (SEQ ID NO: 38). The generation of monoclonal antibodies to well-chosen, unique peptide sequences provides control over epitope specificity, allowing the identification of a particular subpopulation of protein among a pool of closely related isoforms. Blast searches revealed that this peptide has high homology only to SNAP-25 and almost no possible cross-reactivity with other proteins in neuronal cells. The sequence was also carefully scrutinized by utilizing computer algorithms to determine hydropathy index, protein surface probability, regions of flexibility, and favorable secondary structure, followed by proper orientation and presentation of the chosen peptide sequence. The peptide was synthesized and conjugated to Keyhole Limpet Hemocyanin (KLH) to increase immunogenicity. Six Balb/c mice were immunized with this peptide, and after three immunizations in about eight weeks, the mice were bled for testing. The blood was allowed to clot by incubating at 4° C. for 60 minutes. The clotted blood was centrifuged at 10,000×g at 4° C. for 10 minutes to pellet the cellular debris. The resulting serum sample was dispensed into 50 μL aliquots and stored at −20° C. until needed. 
     A similar strategy based on other SNAP-25 antigens disclosed in the present specification is used to develop α-SNAP-25 monoclonal antibodies that can selectively bind to a SNAP-25 having a carboxyl-terminus at the P 1  residue of the BoNT/A cleavage site scissile bond. For example, the SNAP-25 antigen of SEQ ID NO: 45 can be conjugated to KLH instead of the SNAP-25 antigen of SEQ ID NO: 38. As another example, the amino acids 186-197 of human SNAP-25 from the SNAP-25 antigen of SEQ ID NO: 38 can be replaced with SEQ ID NO: 32, SEQ ID NO: 33, SEQ ID NO: 34, SEQ ID NO: 35, SEQ ID NO: 36, SEQ ID NO: 39, SEQ ID NO: 40, SEQ ID NO: 41, SEQ ID NO: 42, SEQ ID NO: 43, SEQ ID NO: 44, SEQ ID NO: 147, or SEQ ID NO: 148. 
     2. Screening for the Presence of α-SNAP-25 Monoclonal Antibodies. 
     To determine the presence of an α-SNAP-25 monoclonal antibody that can selectively bind to a SNAP-25 antigen having a carboxyl-terminus at the P 1  residue of the BoNT/A cleavage site scissile bond, comparative ELISA and cell-based cleavage assay were performed using the extracted mouse serum. For comparative ELISA, two fusion proteins were constructed: BIRA-HIS TAG®-SNAP-25 134-197  of SEQ ID NO: 48 and the BIRA-HIS TAG®-SNAP-25 134-206  of SEQ ID NO: 49. BIRA-HIS TAG®-SNAP-25 134-197  comprised a naturally-biotinylated 16 amino acid BirA peptide of SEQ ID NO: 50 amino-terminally linked to a SNAP-25 peptide comprising amino acids 134-197 of SEQ ID NO: 5. BIRA-HIS TAW-SNAP-25 134-206  comprised a naturally-biotinylated 16 amino acid BirA peptide of SEQ ID NO: 50 amino-terminally linked to a SNAP-25 peptide comprising amino acids 134-206 of SEQ ID NO: 5. These two substrates were suspended in 1×PBS at a concentration of 10 μg/mL BIRA-HIS TAG®-SNAP-25 134-197  and the BIRA-HIS TAG®-SNAP-25 134-206 . The BIRA-HIS TAW-SNAP-25 134-197  and the BIRA-HIS TAG-SNAP-25 134-206  were coated onto separate plates by adding approximately 100 μl of the appropriate Substrate Solution and incubating the plates at room temperature for one hour. Washed plates were incubated at 37° C. for one hour in 0.5% BSA in 1×TBS containing a 1:10 to 1:100 dilution of an antibody-containing serum derived from one of the six immunized mice (Mouse 1, Mouse 2, Mouse 3, Mouse 4, Mouse 5, and Mouse 6). Primary antibody probed plates were washed four times for 5 minutes each time in 200 μl TBS, 0.1% TWEEN-20® (polyoxyethylene (20) sorbitan monolaureate). Washed plates were incubated at 37° C. for 1 hour in 1×TBS containing a 1:10,000 dilution of goat polyclonal anti-mouse IgG antibody conjugated to Horseradish peroxidase (Pierce Biotechnology, Rockford, Ill.) as a secondary antibody. Secondary antibody-probed plates were washed four times in 200 μl TBS, 0.1% TWEEN-20® (polyoxyethylene (20) sorbitan monolaureate). Chromogenic detection of the labeled SNAP-25 products were visualized by chromogenic detection using ImmunoPure TMB substrate kit (Pierce Biotechnology, Rockford, Ill.). The development of a yellow color in the BIRA-HIS TAW-SNAP-25 134-197  coated plates, but not the BIRA-HIS TAG-SNAP-25 134-206  coated plates, indicated that the α-SNAP-25 antibody preferentially recognized the SNAP-25 197  cleavage product. The resulted indicated that of the six mice used for immunization, three mice (Mouse 2, Mouse 3, and Mouse 4) had higher titers and more specificity towards a SNAP-25 antigen having a carboxyl-terminus at the P 1  residue of the BoNT/A cleavage site scissile bond. 
     These results were confirmed using an ELISA light chain activity assay. A 96-well Reacti-Bind Streptavidin coated plates (Pierce Biotechnology, Rockford, Ill.) were prepared by adding approximately 100 μl of the following Substrate Solution: Rows A-C were coated with 100 μL of BIRA-HIS TAW-SNAP-25 134-197  at twelve different concentrations; Rows D-H were coated with 100 μL of BIRA-HIS TAW-SNAP-25 134-206  at 10 μg/mL. The plates were washed by aspirating the Substrate Solution and rinsing each well three times with 200 μl TBS, 0.1% TWEEN-20® (polyoxyethylene (20) sorbitan monolaureate). Dilutions of BoNT/A were pre-reduced at 37° C. for 20 minutes in BoNT/A Incubation Buffer (50 mM HEPES, pH 7.4, 1% fetal bovine serum, 10 pM ZnCl 2 , 10 mM dithiothrietol) and 100 μl of the pre-reduced BoNT/A was added to the substrate-coated plates and incubated at 37° C. for 90 minutes. BoNT/A treated plates were washed by aspirating the BoNT/A Incubation Buffer and rinsing each plate three times with 200 μl TBS, 0.1% TWEEN-20® (polyoxyethylene (20) sorbitan monolaureate). Washed plates were incubated at 37° C. for one hour in 0.5% BSA in 1×TBS containing a 1:10 to 1:100 dilution of the antibody-containing serum being tested. Primary antibody probed plates were washed four times for 5 minutes each time in 200 μl TBS, 0.1% TWEEN-20® (polyoxyethylene (20) sorbitan monolaureate). Washed plates were incubated at 37° C. for 1 hour in 1×TBS containing a 1:10,000 dilution of goat polyclonal anti-mouse IgG antibody conjugated to Horseradish peroxidase (Pierce Biotechnology, Rockford, Ill.) as a secondary antibody. Secondary antibody-probed plates were washed four times in 200 μl TBS, 0.1% TWEEN-20® (polyoxyethylene (20) sorbitan monolaureate). Chromogenic detection of the labeled SNAP-25 products were visualized by chromogenic detection using ImmunoPure TMB substrate kit (Pierce Biotechnology, Rockford, Ill.). The development of a yellow color, which correlated with the presence of the SNAP-25 197  cleavage product was detected in BoNT/A treated samples, but not untreated controls, using antibody-containing serum derived from all six immunized mice (Mouse 1, Mouse 2, Mouse 3, Mouse 4, Mouse 5, and Mouse 6). Thus, the comparative ELISA analysis indicated that of the mice used for immunization, three mice (Mouse 2, Mouse 3, and Mouse 4) had higher titers and more specificity towards a SNAP-25 antigen having a carboxyl-terminus at the P 1  residue of the BoNT/A cleavage site scissile bond. 
     For cell-based cleavage assay, a suitable density of PC12 cells were plated into 60 mm 2  tissue culture plates containing 3 mL of an appropriate serum medium (Table 1). The cells were grown in a 37° C. incubator under 5% carbon dioxide until cells reached the appropriate density. A 500 μL transfection solution was prepared by adding 250 μL of OPTI-MEM® Reduced Serum Medium containing 15 μL of LIPOFECTAINE® 2000 (Invitrogen Inc., Carlsbad, Calif.) incubated at room temperature for 5 minutes to 250 μL of OPTI-MEM® Reduced Serum Medium containing 10 μg of a pQBI-25/GFP-BoNT/A-LC expression construct (SEQ ID NO: 51). The pQBI-25/GFP-BoNT/A-LC expression construct comprises a pQBI-25 expression vector (Qbiogene Inc., Carlsbad, Calif.) whose promoter elements are functionally linked to a polynucleotide encoding the GFP-BoNT/A light chain of SEQ ID NO: 52. This transfection mixture was incubated at room temperature for approximately 20 minutes. The media was replaced with fresh unsupplemented media and the 500 μL transfection solution was added to the cells. The cells were then incubated in a 37° C. incubator under 5% carbon dioxide for approximately 6 to 18 hours. The cells were washed and harvested as described in Example II. To detect for the presence of the cleaved SNAP-25 197  product, an aliquot from each harvested sample was analyzed by Western blot as described in Example II, except that the primary antibody used was a 1:1,000 dilution of the antibody-containing serum and the secondary antibody used was a 1:20,000 of mouse α-IgG Horseradish Peroxidase (Pierce Biotechnology, Rockford, Ill.). A single band corresponding to the SNAP-25 197  cleavage product was detected in BoNT/A treated samples, but not untreated controls, using antibody-containing serum derived from three mice (Mouse 2, Mouse 3, and Mouse 4). Thus, the cell-based cleavage assay indicated that of the mice used for immunization, three mice (Mouse 2, Mouse 3, and Mouse 4) had higher titers and more specificity towards a SNAP-25 antigen having a carboxyl-terminus at the P 1  residue of the BoNT/A cleavage site scissile bond. 
     3. Production of Hybridomas. 
     To make hybridomas producing α-SNAP-25 monoclonal antibodies that can selectively bind to a SNAP-25 antigen having a carboxyl-terminus at the P 1  residue of the BoNT/A cleavage site scissile bond, the spleen from Mouse 2 was harvested three days subsequent to a final “booster” immunization and the spleen cells were fused with myeloma cells P3-X63 Ag8.653 using standard hybridoma protocols. These cells were plated into five 96-well plates and hybrids were selected using HAT medium. Within 8-14 days after fusion, the first screening of the approximately 480 parent clones was carried out using comparative ELISA with the BIRA-HIS TAW-SNAP-25 134-197  and the BIRA-HIS TAW-SNAP-25 134-206  peptides coated in two separate plates. The comparative ELISA provided a quick screen method to identify hybridomas producing antibodies specific for the cleaved SNAP-25 197 . The top 18 clones were subjected to further screening using the cell-based cleavage assay described above and immunostaining of LC/A transfected cells. (Table 18).

     Clones 1 D3, 1G10, 2E2, 3C1, 3C3, and 3E8 were further cloned by limiting dilution because the conditioned media produced by these clones comprised α-SNAP-25 antibodies with a preferential binding specificity having a ratio 197/206  of at least 4:1 for the SNAP-25 197  cleavage product relative to the SNAP-25206 uncleaved substrate and detected the SNAP-25 197 -cleavage product using the cell-based cleavage assay and the immunostaining of PC12 cells transfected with GFP-LC/A. Similarly clones 2C9, 2F11, 3G2, 4D1 and 4G6 were further cloned by limiting dilution because the conditioned media produced by these clones comprised α-SNAP-25 antibodies with a preferential binding specificity having a ratio 206/197  of at least 1.5:1 for the SNAP-25 206  uncleaved substrate relative to the SNAP-25 197  cleavage product and detected the SNAP-25 206 -uncleaved substrate using the cell-based cleavage assay. These single-cell derived clones were screened again using comparative ELISA, cell-based cleavage, and immunostaining to confirm their affinity and specificity, and the antibodies were isotyped using standard procedures. Ascites were produced from clones 1D3B8 (IgM.k), 1G10A12 (IgG3.k), 2C9B10 (IgG3.k), 2E2A6 (IgG3.k), 2F11B6 (IgM.k), 3C1A5 (IgG2a.k), and 3C3E2 (IgG2a.k). Clone 3E8 stopped producing antibodies during the cloning process and could not be further evaluated. 
     4. Evaluation of Binding Specificity of α-SNAP-25 Monoclonal Antibodies. 
     To evaluate binding specificity of an α-SNAP-25 monoclonal antibody that can selectively bind to a SNAP-25 antigen having a carboxyl-terminus at the P 1  residue of the BoNT/A cleavage site scissile bond, ascites from clones 1 D3B8, 1G10A12, 2C9B10, 2E2A6, 2F11B6, 3C1A5, and 3C3E2 were used to detect SNAP-25 cleavage product using the cell-based activity assay, immunocytochemistry and immunoprecipitation. 
     For the cell-based activity assay, binding specificity was determined by analyzing the ability of α-SNAP-25 antibody-containing ascites to detect the uncleaved SNAP-25 206  substrate and the cleaved SNAP-25 197  product by Western blot analysis. A suitable density of PC12 cells were plated into 60 mm 2  tissue culture plates containing 3 mL of an appropriate serum medium, grown in a 37° C. incubator under 5% carbon dioxide until an appropriate cell density was reached, and transfected with the either a transfection solution lacking the pQBI-25/GFP-BoNT/A-LC expression construct (untransfected cells) or a transfection solution containing the pQBI-25/GFP-BoNT/A-LC expression construct (transfected cells) as described above. The cells were washed and harvested as described in Example I. To detect for the presence of both the uncleaved SNAP-25 206  substrate and the cleaved SNAP-25 197  product, an aliquot from each harvested sample was analyzed by Western blot as described in Example I, except that the primary antibody used was a 1:100 dilution of the α-SNAP-25 monoclonal antibody-containing ascites and the secondary antibody used was a 1:20,000 of α-mouse IgG conjugated to Horseradish Peroxidase (Pierce Biotechnology, Rockford, Ill.). In addition, three commercially available mouse α-SNAP-25 monoclonal antibodies were tested. SMI-81 (Sternberger Monoclonals Inc., Lutherville, Md.), an α-SNAP-25 antibody the manufacturer indicates detects both the uncleaved SNAP-25 206  substrate and the cleaved SNAP-25 197  product, was used at a 15,000 dilution according to the manufacturer&#39;s recommendations. MC-6050 (Research &amp; Diagnostic Antibodies, Las Vegas, Nev.), an α-SNAP-25 antibody the manufacturer indicates detects both the uncleaved SNAP-25 206  substrate and the cleaved SNAP-25 197  product, was used at a 1:100 dilution according to the manufacturer&#39;s recommendations. MC-6053 (Research &amp; Diagnostic Antibodies, Las Vegas, Nev.), an α-SNAP-25 antibody the manufacturer indicates detects only the cleaved SNAP-25 197  product, was used at a 1:100 dilution according to the manufacturer&#39;s recommendations. 
     Table 19 indicates the α-SNAP-25 antibody-containing ascites that detected only the SNAP-25 197  cleavage product. The cell-based cleavage assay indicated that ascites produced from clones 1 D3B8, 2C9B10, 2E2A6, 3C1A5, and 3C3E2 synthesize an α-SNAP-25 monoclonal antibody having high binding specificity for the SNAP-25 197  cleavage product that allows for the selective recognition of this cleavage product relative to the SNAP-25 206  uncleaved substrate. Commercial antibody SMI-81 detected the SNAP-25 206  uncleaved substrate, but only poorly recognized the SNAP-25 197  cleavage product (Table 19). Surprisingly, commercial antibody MC-6050 only detected the SNAP-25 206  uncleaved substrate, and failed to recognize the SNAP-25 197  cleavage product (Table 19). Even more surprisingly, commercial antibody MC-6050 only detected the SNAP-25 206  uncleaved substrate, and failed to recognize the SNAP-25 197  cleavage product, even though the manufacturer advertises that this antibody selectively detects the SNAP-25 197  cleavage product (Table 19). Thus, this analysis indicates that while 1 D3B8, 2C9B10, 2E2A6, 3C1A5, and 3C3E2 exhibit suitable selectivity for the SNAP-25 197  cleavage product, 1G10A12 and 2F11B6 do not. In addition, commercial antibodies SMI-81, MC-6050 and MC-6053 all are unsuitable for the immuno-based methods disclosed in the present application because all failed to selectivity detect the SNAP-25 197  cleavage product. 
     For immunocytochemistry analysis, binding specificity was determined by analyzing the ability of α-SNAP-25 antibody-containing ascites to detect the uncleaved SNAP-25 206  substrate and the cleaved SNAP-25 197  product by immunostaining. See e.g., Ester Fernandez-Salas et al.,  Plasma Membrane Localization Signals in the Light Chain of Botulinum Neurotoxin , Proc. Natl. Acad. Sci., U.S.A. 101(9): 3208-3213 (2004). A suitable density of PC12 cells were plated, grown, and transfected with either a transfection solution lacking the pQBI-25/GFP-BoNT/A-LC expression construct (untransfected cells) or a transfection solution containing the pQBI-25/GFP-BoNT/A-LC expression construct (transfected cells) as described above. The cells were washed in 1×PBS and fixed in 5 mL of PAF at room temperature for 30 minutes. Fixed cells were washed in phosphate buffered saline, incubated in 5 mL of 0.5% Triton® X-100 (polyethylene glycol octylphenol ether) in 1×PBS, washed in 1×PBS, and permeabilized in 5 mL of methanol at −20° C. for six minutes. Permeabilized cells were blocked in 5 mL of 100 mM glycine at room temperature for 30 minutes, washed in 1×PBS, and blocked in 5 mL of 0.5% BSA in 1×PBS at room temperature for 30 minutes. Blocked cells were washed in 1×PBS and incubated at room temperature for two hours in 0.5% BSA in 1×PBS containing a 1:10 dilution of an ascites from a clonal hybridoma cell line being tested. Primary antibody probed cells were washed three times for 5 minutes each time in 1×PBS. Washed cells were incubated at room temperature for 2 hours in 1×PBS containing a 1:200 dilution of goat polyclonal anti-mouse immunoglobulin G, heavy and light chains (IgG, H+L) antibody conjugated to ALEXA® FLUOR 568 (Invitrogen Inc., Carlsbad, Calif.) as a secondary antibody. Secondary antibody-probed cells were washed three times for 5 minutes each time in 1×PBS. Washed cells were prepared for microscopic examination by mounting in VECTASHIELD® Mounting Media (Vector Laboratories, Burlingame, Calif.) and coverslipped. Images of signal detection were obtained with a Leica confocal microscope using appropriate laser settings. Table 19 indicates that the α-SNAP-25 antibody-containing ascites that specifically detected the SNAP-25 197 -cleavage product. The immunocytochemistry analysis indicated that ascites produced from clones 1D3B8, 2C9B10, 2E2A6, 3C1A5, and 3C3E2 synthesize an α-SNAP-25 monoclonal antibody having high binding specificity for the SNAP-25 197  cleavage product that allows for the preferential recognition of this cleavage product relative to the SNAP-25206 uncleaved substrate. 
     For immunoprecipitation analysis, binding specificity was determined by analyzing the ability of Protein A (HiTrap™ Protein A HP Columns, GE Healthcare, Amersham, Piscataway, N.J.), purified α-SNAP-25 monoclonal antibodies to precipitate the uncleaved SNAP-25 206  substrate and the cleaved SNAP-25 197  product. See e.g., Chapter 8  Storing and Purifying Antibodies , pp. 309-311, Harlow &amp; Lane, supra, 1998a. A suitable density of PC12 cells were plated, grown, and transfected with either a transfection solution containing a pQBI-25/GFP expression construct (control cells; SEQ ID NO: 53) or a transfection solution containing the pQBI-25/GFP-BoNT/A-LC expression construct (experimental cells) as described above. The pQBI-25/GFP expression construct comprises an expression vector whose promoter elements are functionally linked to a polynucleotide encoding GFP of SEQ ID NO: 54. After an overnight incubation, the cells were washed by aspirating the growth media and rinsing each well with 200 μL 1×PBS. To harvest the cells, the PBS was aspirated, the cells were lysed by adding an Immunoprecipitation Lysis Buffer comprising 50 mM HEPES, 150 mM NaCl, 1.5 mM MgCl 2 , 1 mM EGDT, 10% glycerol, 1% Triton® X-100 (polyethylene glycol octylphenol ether) and a 1× COMPLETE™ Protease inhibitor cocktail (Roche Applied Biosciences, Indianapolis, Ind.) and incubating at 4° C. for one hour. The lysed cells were centrifuged at 3,000×g at 4° C. for 10 minutes to remove cellular debris and the supernatant transferred to a clean tube and diluted to a protein concentration of approximately 1 mg/mL. Approximately 5 μg of purified monoclonal antibody was added to 0.5 mL of diluted supernatant and incubated at 4° C. for two hours. After primary antibody incubation, approximately 50 μl of immobilized Protein G (Pierce Biotechnology, Rockford, Ill.) was added to the diluted supernatant and incubated at 4° C. for one hour. The incubated supernatant was washed three times for 30 minutes each time by adding 0.5 mL of Immunoprecipitation Lysis Buffer, centrifuging at 300×g at 4° C. for one minute to pellet the immobilized Protein G, and decanting the supernatant. After washing, the pellet was resuspended in 30 μL of 1×SDS Loading Buffer and the sample was heated to 95° C. for 5 minutes. To detect for the presence of both the uncleaved SNAP-25 206  substrate and the cleaved SNAP-25 197  product, an aliquot from each harvested sample was analyzed by Western blot as described in Example I, except that the primary antibody used was a 1:1,000 dilution of the α-SNAP-25 polyclonal antibody serum (see Example IV) and the secondary antibody used was a 1:20,000 of rabbit α-IgG Horseradish Peroxidase (Pierce Biotechnology, Rockford, Ill.). Table 19 indicates the α-SNAP-25 antibody-containing ascites that specifically pulled down the SNAP-25 197 -cleavage product by immunoprecipitation analysis. The immunoprecipitation analysis indicated that ascites produced from clones 2E2A6 and 3C1A5 synthesize an α-SNAP-25 monoclonal antibody having high binding specificity for the SNAP-25 197  cleavage product that allows for the preferential recognition of this cleavage product relative to the SNAP-25 206  uncleaved substrate.

     5. Evaluation of Binding Affinity of α-SNAP-25 Monoclonal Antibodies. 
     To determine the binding affinity of an α-SNAP-25 monoclonal antibody showing high binding specificity for either the SNAP-25 197  cleavage product or the SNAP-25 206  uncleaved substrate, binding affinity assays were performed on a BIACORE 3000 instrument using carboxymethyl dextran (CM5) sensor chips (BIAcore, Inc., Piscataway, N.J.). Runs were conducted at 25° C. with HBS-EP buffer comprising 10 mM HEPES (pH 7.4), 150 mM sodium chloride, 3 mM EDTA, 0.005% (v/v) surfactant P20 at a flow rate of 10 μl/min. SNAP-25 peptides comprising amino acids 134-197 of SEQ ID NO: 5 (SNAP-25 134-197 ) or amino acids 134-206 of SEQ ID NO: 5 (SNAP-25 134-206 ) were covalently attached to the surface of the CM5 sensor chips using standard amine coupling. Briefly, the CM5 chips were activated by a 7 minute injection of a mixture of 0.2 M 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide and 0.05 M N-hydroxysuccimide; the SNAP-25 peptides were then injected in 10 mM sodium acetate (pH 4.0) for 20 min at a flow rate of 10 μL/min; and unreacted succimide esters were blocked by a 7-min injection of 1 M ethanolamine hydrochloride, pH 8.5. The immobilized amount of SNAP-25 134-197  or SNAP-25 134-206  on the chip was reflected by a 100-150 increase in response units (about 0.10-0.15 ng/mm 2 ). Antibody samples comprising either ascites or purified monoclonal antibodies produced from clones 1D3B8, 2C9B10, 2E2A6, 3C1A5, and 3C3E2, as well as, commercially available α-SNAP-25 antibodies were passed over the surface of the CM5 chips allowing an association time of 10 min and a dissociation time of 20 min. The surfaces were regenerated between runs by a 1 minute injection of 10 mM glycine-HCl (pH 2.5) at a flow rate of 15 μL/min. Sensorgram curves were fitted to a 1:1 kinetic binding model with the BIAevaluation 3.0 software. 
     The results indicate that both 2E2A6 and 3C1A5 were highly specific for cleaved SNAP-25 197  product over SNAP-25 uncleaved substrate (Table 20). When compared to the binding affinities of MC-6050 and MC-6053, 1 D3B6 had an approximately 10-fold higher equilibrium disassociation constant for the SNAP-25 cleavage product relative to these commercial antibodies (Table 20). Interestingly, 2E2A6 had only a slightly lower equilibrium disassociation constant for the SNAP-25 cleavage product relative to these commercial antibodies (0.405 nM versus 0.497 and 0.508)(Table 20). As neither of these commercial α-SNAP-25 antibodies selectively recognized the SNAP-25 cleavage product (Table 19), an equilibrium disassociation constant lower than about 0.5 nM appears, in part, critical to achieve such selectivity. Similarly, when compared to the binding affinities of MC-6050 and MC-6053, 2E2A6 had an about at least one-fold slower off rate/dissociation constant (6.74×10 −5  versus 8.82×10 −4  s −1  and 1.18×10 −3  s −1 ) (Table 20). This further suggests that an off rate/dissociation constant lower than about 8.82×10 −4  appears, in part, critical to achieve selective binding for the SNAP-25 cleavage product. This result is consistent with 1 D3B8, which had an off rate/dissociation constant of 5.78×10 −5  s −1  (Table 20).

     To compare the six different antibodies, the on-rate (ka) and off-rate (kd) for each was normalized using a program from the BIA evaluation 4.1 software. For comparison of the on-rates, the data were first individually trimmed by deleting the re-generation portion and the injection spikes, and then normalized to a 0 to 100 scale. For comparison of the off-rate, the data were normalized to the injection stop/top point. This analysis showed that 2C9B10 had a much slower on-rate than the other antibodies ( FIG. 3A ), and that MC-6053 has a much faster off-rate (dissociation) that the other antibodies ( FIG. 3B ). The fast off-rate of MC-6053 indicates that this antibody will not perform well in the methods disclosed in the present specification because this antibody will have difficulty staying bound to the substrate antigen during the washing steps. 
     6. Sequencing of the Epitope from Isolated α-SNAP-25 Monoclonal Antibodies. 
     To determine the epitope of an isolated α-SNAP-25 monoclonal antibody that can selectively bind to a SNAP-25 antigen having a carboxyl-terminus at the P 1  residue of the BoNT/A cleavage site scissile bond, the polynucleotide molecule encoding the variable heavy (V H ) and variable light (V L ) chains of the α-SNAP-25 monoclonal antibody produced by hybridomas 1D3B8, 2C9B10, 2E2A6, 3C1A5 and 3C3E2 were sequenced. mRNA was extracted and purified from each hybridoma using standard protocols and reversed transcribed into cDNA using either an oligo dT anti-sense primer or a gene-specific (murine IgG1 CH and kappa CL) anti-sense primer. Specific murine and human constant domain primers were used to amplify the cDNA by PCR after cDNA production to determine the isotype of the antibody. Degenerate V H  and V L  primers were used to amplify the variable domains from the cDNA. For 5′RACE, a homopolymeric dCTP tail was added to the 3′ end of the cDNA. The heavy and light chains were then amplified with an oligo dG sense primer and a gene specific (CH/KC) anti-sense primer. PCR products included the sequence of the signal peptide, variable domains and constant domains up to the anti-sense primer. The PCR products were gel purified to remove small fragments, and cloned into a blunt or TA vector for sequencing. Five independent clones for each chain were sequenced and alignments of V H  and V L  chains and consensus sequences were determined. Methods used to determine the V H  and V L  amino acid sequences are described in, e.g., Roger A. Sabbadini, et al., Novel Bioactive Lipid Derivatives and Methods of Making and Using Same, U.S. Patent Publication 2007/0281320; and Peter Amersdorfer, et al., Molecular Characterization of Murine Humoral Immune Response to Botulinum Neurotoxin Type A Binding Domain as Assessed by Using Phage Antibody Libraries, 65(9) Infect. Immun. 3743-3752, each of which is hereby incorporated by reference in its entirety. In addition, commercial services are available to sequence the variable heavy (V H ) and variable light (V L ) chains of an antibody and identify the CDR regions, see, e.g., Fusion Antibodies Ltd., Northern Ireland. 
     The polynucleotide sequence comprising the V H  and V L  chains of the α-SNAP-25 monoclonal antibody produced by the hybridomas disclosed in the present specification is as follows: 1 D3B8 V H  (SEQ ID NO: 71), 2C9B10 V H  (SEQ ID NO: 73), 2E2A6 V H  (SEQ ID NO: 75), 3C1A5 V H  (SEQ ID NO: 77), 3C3E2 V H  variant 1 (SEQ ID NO: 79), 3C3E2 V H  variant 2 (SEQ ID NO: 81), 3C3E2 V H  variant 3 (SEQ ID NO: 149), 1D3B8 V L  (SEQ ID NO: 83), 2C9B10 V L  (SEQ ID NO: 85), 2E2A6 V L  (SEQ ID NO: 87), 3C1A5 V L  (SEQ ID NO: 89), and 3C3E2 V L  (SEQ ID NO: 91). The amino acid sequence comprising the V H  and V L  chains of the α-SNAP-25 monoclonal antibody produced by the hybridomas disclosed in the present specification is as follows: 1 D3B8 V H  (SEQ ID NO: 72), 2C9B10 V H  (SEQ ID NO: 74), 2E2A6 V H  (SEQ ID NO: 76), 3C1A5 V H  (SEQ ID NO: 78), 3C3E2 V H  variant 1 (SEQ ID NO: 80), 3C3E2 V H  variant 2 (SEQ ID NO: 82); 3C3E2 V H  variant 2 (SEQ ID NO: 150), 1D3B8 V L  (SEQ ID NO: 84), 2C9B10 V L  (SEQ ID NO: 86), 2E2A6 V L  (SEQ ID NO: 88), 3C1A5 V L  (SEQ ID NO: 90), and 3C3E2 V L  (SEQ ID NO: 92). The amino acid sequences comprising the V H  and V L  CDR domains of the α-SNAP-25 monoclonal antibody produced by the hybridomas 1 D3B8, 2C9B10, 2E2A6, 3C1A5, and 3C3E2 are given in Table 21.

     Example IX 
     Development of α-SNAP-25 Polyclonal Antibodies that Selectively Bind a SNAP-25 Epitope Having a Free Carboxyl-Terminus at the P 1  Residue of the BoNT/a Cleavage Site Scissile Bond 
     The following example illustrates how to make α-SNAP-25 polyclonal antibodies that can selectively bind to a SNAP-25 epitope having a carboxyl-terminus at the P 1  residue of the BoNT/A cleavage site scissile bond. 
     To develop α-SNAP-25 polyclonal antibodies that bind an epitope comprising a carboxyl-terminus at the P1 residue from the BoNT/A cleavage site scissile bond from a SNAP-25 cleavage product, the 10-residue peptide CGGGRIDEANQ (SEQ ID NO: 46) was designed as a SNAP-25 cleavage product antigen. This peptide comprising a N-terminal Cysteine residue for conjugation to KLH, a G-spacer flexible spacer (GGG) linked to amino acids 191-197 of human SNAP-25 (SEQ ID NO: 5) and has a carboxylated C-terminal glutamine. Blast searches revealed that this peptide has high homology only to SNAP-25 and almost no possible cross-reactivity with other proteins in neuronal cells. The sequence was also carefully scrutinized by utilizing computer algorithms to determine hydropathy index, protein surface probability, regions of flexibility, and favorable secondary structure, followed by proper orientation and presentation of the chosen peptide sequence. The peptide was synthesized and conjugated to Keyhole Limpet Hemocyanin (KLH) to increase immunogenicity. Before the animals were immunized, naïve rabbits were first screened against cell lysates from candidate cell lines in a Western blot in order to identify animals that had no immunoreactivity to the proteins present in the cell lysates. Two pre-screened rabbits were immunized with this peptide, and after three immunizations in about eight weeks, the rabbits were bled for testing. The blood was allowed to clot by incubating at 4° C. for 60 minutes. The clotted blood was centrifuged at 10,000×g at 4° C. for 10 minutes to pellet the cellular debris. The resulting serum sample was dispensed into 50 μL aliquots and stored at −20° C. until needed. 
     A similar strategy based on other SNAP-25 antigens disclosed in the present specification is used to develop α-SNAP-25 polyclonal antibodies that bind an epitope comprising a carboxyl-terminus at the P1 residue from the BoNT/A cleavage site scissile bond from a SNAP-25 cleavage product. For example, the SNAP-25 antigen of SEQ ID NO: 47 can be conjugated to KLH instead of the SNAP-25 antigen of SEQ ID NO: 46. As another example, the amino acids 191-197 of human SNAP-25 from the SNAP-25 antigen of SEQ ID NO: 38 can be replaced with SEQ ID NO: 33, SEQ ID NO: 34, SEQ ID NO: 35, SEQ ID NO: 36, SEQ ID NO: 37, SEQ ID NO: 39, SEQ ID NO: 40, SEQ ID NO: 41, SEQ ID NO: 42, SEQ ID NO: 43, or SEQ ID NO: 44. 
     2. Screening for the Presence of α-SNAP-25 Polyclonal Antibodies. 
     To determine the presence of α-SNAP-25 polyclonal antibodies that can selectively bind to a SNAP-25 antigen having a carboxyl-terminus at the P1 residue of the BoNT/A cleavage site scissile bond, comparative ELISA and cell-based cleavage assays were performed using the extracted rabbit serum as described in Example VIII. The serum from both rabbits contained α-SNAP-25 polyclonal antibodies that can selectively bind to a SNAP-25 antigen having a carboxyl-terminus at the P1 residue of the BoNT/A cleavage site scissile bond. The α-SNAP-25 rabbit polyclonal antibodies were designated as NTP 22 and NTP 23. 
     3. Purification of α-SNAP-25 Polyclonal Antibodies. 
     To purify α-SNAP-25 polyclonal antibodies that can selectively bind to a SNAP-25 antigen having a carboxyl-terminus at the P 1  residue of the BoNT/A cleavage site scissile bond, NTP 22 and NTP 23 antibodies from rabbit serum were purified using affinity columns containing the SNAP-25 antigen of SEQ ID NO: 46. 
     4. Evaluation of Binding Specificity of α-SNAP-25 Polyclonal Antibodies. 
     To evaluate binding specificity of an α-SNAP-25 polyclonal antibody that can selectively bind to a SNAP-25 antigen having a carboxyl-terminus at the P 1  residue of the BoNT/A cleavage site scissile bond, purified NTP 22 and NTP 23 α-SNAP-25 polyclonal antibodies were used to detect cleavage product using the cell-based activity assay, immunocytochemistry and immunoprecipitation as described in Example VIII. The cell-based cleavage assay, immunocytochemistry analysis and immunoprecipitation analysis all indicated that NTP 22 and NTP 23 α-SNAP-25 polyclonal antibodies did not cross-react with uncleaved SNAP-25. Thus both NTP 22 and NTP 23 have high binding specificity for the SNAP-25 197  cleavage product that allows for the preferential recognition of this cleavage product relative to the SNAP-25 206  uncleaved substrate. Affinity for the antigens can be determined using SPR in the BiAcore as described in Example VIII. 
     Unless otherwise indicated, all numbers expressing quantities of ingredients, properties such as molecular weight, reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term “about.” Accordingly, unless indicated to the contrary, the numerical parameters set forth in the specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by the present invention. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques. Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the invention are approximations, the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements.
