## Background
This application is a 371 of PCT/GB10/50018 filed Jan. 7, 2010, which claims foreign priority to British Application No. 0900151.2, filed Jan. 7, 2009.
REFERENCE TO A SEQUENCE LISTING SUBMITTED ELECTRONICALLY VIA EFS-WEB
The content of the sequence listing (Name: Sequence_Listing.txt, Size: 180,647 bytes; and Date of Creation: Jul. 6, 2011) electronically submitted via EFS-Web is incorporated by reference in its entirety.
The invention relates to the field of rapid bioluminescence detection systems, in particular to rapid and very sensitive bioluminescence detection systems for detecting the activity of reporter kinases. Bioluminescent assays, devices, and kits for detecting the activity of reporter kinases are also provided.
The use of kinases as reporter enzymes has been described in the art. By way of example, the present inventors have described the use of reporter kinases in diagnostic systems for detecting the presence of an analyte in a sample (see WO00/46357), and also in systems for validating the effectiveness of decontamination processes (see WO2005/093085). The activity of these reporter kinases is typically detected using an ATP bioluminescence system (e.g. luciferin-luciferase), which generates a light output signal. The light output generated is measured using a luminometer, and these measurements are then correlated with the amount of kinase activity.
A potential problem associated with reporter kinase systems is the length of time required to obtain the output signal. To date, the typical time required to obtain an output signal ranges from 30 minutes to several hours. There is thus a need in the art for a quicker and/or simplified reporter system.
One or more of the above-mentioned problems is solved by the present invention, which, in a first aspect, provides an assay for detecting the activity of a reporter kinase, comprising:
(i) adding said reporter kinase to an assay mixture, wherein said reporter kinase contacted with ADP, and, no more than 5 minutes after being contacted with ADP, said reporter kinase is contacted with a bioluminescent reagent,
wherein, prior to contacting the reporter kinase with ADP, the assay mixture is substantially free from non-reporter kinase (ie. kinase other than reporter kinase); and
(ii) detecting light output from the assay mixture.
In one embodiment of the invention, the method further comprises the step of recording the light output data obtained in step (ii) on a suitable data carrier.
In another embodiment of the invention, the reporter kinase is contacted with the bioluminescent reagent no more than 2 minutes, no more than 1 minute, no more than 30 seconds, or no more than 10 seconds, after being contacted with the ADP. In another embodiment, the reporter kinase is contacted simultaneously with the ADP and the bioluminescent reagent.
Thus, there is no significant incubation period (or only a very short incubation period) between contacting the reporter kinase with the ADP and contact with the bioluminescent reagent. The invention can therefore be said to employ a “one-step” bioluminescent detection process.
In contrast to the above rapid detection system, conventional reporter systems typically employ a “two-step” detection process:




In the first step, the reporter kinases are exposed to a source of ADP substrate, and incubated for a sufficient time to sallow the generation of ATP [1]. Then, in a second, separate, step, the luciferin/luciferase reagent is added to convert the ATP generated by the reporter kinase into light [2]. This “two-step” bioluminescent assay has been shown to provide accurate kinase detection. However, its “two-step” nature (i.e. the addition of ADP, incubation, and then separate addition of bioluminescent reagent) has proved cumbersome and slow when detection is carried out “in the field”, and not in a laboratory setting.
To date, the two reaction steps (illustrated above) have been considered incompatible as AMP generated during step [2] drives the equilibrium of step [1] over to the left-hand side, thereby favoring the re-conversion of ATP generated in step [1] into ADP. Since the light signal output of the system is dependent on the presence of ATP, this makes the detection of kinase activity more difficult. Thus, to date, steps [1] and [2] have been separated either temporally (i.e. by including an incubation step as described above), or spatially (i.e. where the reactions are carried out in separate compartments).
Contrary to this dogma, the present inventors have found that reaction steps [1] and [2] can in fact be performed simultaneously, without any significant adverse effect on the sensitivity of the detection of the reporter kinases. The resulting “one-step” bioluminescent assay provides significant advantages in terms of speed and convenience, and is particularly advantageous in point-of-care diagnostic tests, and rapid process release indicators, i.e. for the detection of kinase activity in the field rather than in the laboratory.
In addition, in order to ensure a high sensitivity and accuracy of detection, the present inventors have found it advantageous to ensure that, prior to the addition of any ADP, the sample containing the reporter kinase is substantially free from any non-reporter (ie. contaminating) kinase activity, and/or any endogenous ATP. As will be clear from the reaction schemes above, the presence of either of these contaminants can significantly adversely affect the sensitivity/accuracy of the detection of kinase activity. By way of example, non-reporter kinases may convert ADP to ATP and thus generate a false for increased) light output signal. Thus, it has been found advantageous to treat the sample containing the reporter kinase to remove or inactivate any non-reporter kinase and/or any endogenous ATP.
In one embodiment of the invention, non-reporter kinase is removed and/or inactivated using one or more of the treatment steps described below. In this regard, preferred non-reporter kinases that are inactivated or removed in accordance with the present invention are mammalian, fungal and/or plant kinases (eg. a mammalian, fungal or plant adenylate kinase). These treatments may be used in any number (preferably one or more, or at least two, or at least three) and/or in any combination. In all cases, however, the treatment leaves the reporter kinase substantially intact (eg. active in terms of kinase activity). Any one or more of the following treatment steps can be applied to any aspect of the invention.
In one embodiment, non-reporter kinase is inactivated by exposure to a temperature of between 50 to 120 C for a period of between 1 and 30 minutes, for example 90 C for 10 minutes, 90 C for 3 minutes, 90 C for 1 minute, 120 C for 3 minutes, or 120 C for 1 minute. The temperature and duration of the inactivation process denature non-reporter kinase whilst leaving the activity of the reporter kinase substantially intact.
In a further embodiment, non-reporter kinase is removed/inactivated using a chemical denaturation treatment. Example of suitable treatments include exposure to a chaotrope such as urea (e.g. concentrations greater than 2M urea) or guanidine (e.g. concentrations greater than 1M guanidine), exposure to a detergent (e.g. greater than 0.5% SOS, sarcosyl or triton X-100) exposure to a free-radical generator (e.g. >1000 ppm active chlorine derived from sodium hypochlorite or equivalent reagents) or exposure to an oxidative treatment.
In another embodiment, non-reporter kinase is removed/inactivated using an enzymatic denaturation treatment. Examples of suitable enzymes include highly processive proteases, such as e.g. Prionzyme®, Properase®, proteinase-K, and thermolysin.
In a further embodiment, non-reporter kinase is removed/inactivated by exposure to a selected pH (e.g. below pH 4, or greater than pH 11 using buffers such as 50 mM CAPS pH 11), a selected salt concentration (e.g. >2M ammonium sulphate), EDTA, or combinations thereof.
In a further embodiment, non-reporter kinase is removed/inactivated by the addition of an inhibitor, which selectively or specifically inhibits the non-reporter kinase (i.e. the inhibitor inactivates the non-reporter kinase, whilst leaving the activity of the reporter kinase substantially intact). Examples of suitable inhibitors include: staurosporine; vanadate (eg. orthovanadate or decavanadate); glycerophosphate; Diadenosine phosphates such as Ap6A (Diadenosine hexaphosphate), Ap5A (Diadenosine pentaphosphate), Ap4A (Diadenosine tetraphosphate), and/or Ap3A (Diadenosine triphosphate); vitamin C; AMP-PCP; AMP-PNP; AMP-S; ATP-γS; and Ara-ATP. Competitive inhibitors of non-reporter kinases (eg. of non-reporter adenylate kinase) are preferred (eg. Diadenosine phosphate inhibitors such as Ap4A and/or Ap5A), in one embodiment, the inhibitor selectively or specifically inhibits mammalian and fungal (eg. yeast) and plant non-reporter kinases. In another embodiment, the inhibitor (eg. Ap5A) selectively or specifically inhibits mammalian and fungal (eg. yeast) non-reporter kinases. In a further embodiment, the inhibitor (eg. Ap4A and/or Ap6A) selectively or specifically inhibits mammalian non-reporter kinases.
Inhibitors may be determined empirically, for example for different samples or matrices. For example a range of different inhibitors have been shown experimentally to provide discrimination between a reporter kinase (e.g. a kinase from S. acidocaldarius, T. maritima, or Chlamydia pneumonae) and a non-reporter kinase such as a mammalian tissue-derived kinase as represented by rabbit muscle adenylate kinase (FIG. 4 and FIG. 7). Thus, in one embodiment, the use of one or more inhibitor such as Ap4A, Ap5A and/or Ap6A substantially reduces the activity of non-reporter kinase (eg. endogenous tissue-derived kinase such as adenylate kinase)—the employed inhibitor concentrations are typically in the low micromolar range and have no significant effect on a reporter kinase. By way of further example, Ap5A discriminates reporter kinase from non-reporter kinase (eg. fungal adenylate kinase) represented here by the enzyme from Saccharomyces cerevisiae. On this basis inhibitor selection may be based on both the nature of the reporter kinase and the background (ie. non-reporter kinase) of the sample.
Examples of suitable reporter kinase applications of the present invention are illustrated in Table 1 (below)—also shown are examples of contaminating non-reporter kinases typically encountered in said applications. Table 1 also lists, purely by way of example, a selection of inhibitors that may be employed (eg. by addition to sample preparation buffers) in the context of the present invention.

In another embodiment, non-reporter kinase may be separated from reporter kinase on the basis of size. By way of example, the sample containing the reporter kinase can be run on a filtration device, which separates the non-reporter kinase and the reporter kinase on the basis of size, with the reporter kinase being retained on a suitable filter whilst the non-reporter kinase passes through (see e.g. Example 14, and FIG. 6). This may be achieved by coupling the reporter kinase to a particle or within a vesicle which is preferentially retained by the filter. In either case the adherence of the reporter kinase to the filter does not result in the significant loss of the reporter kinase activity. Suitable filter matrices include: nitrocellulose, cellulose acetate or paper filters. Fitter matrices typically employ a range of pore sizes, such as from 0.2 μm to 20 μm or larger depending on the nature of the particulate carrier employed.
Physical size may also be used as a basis for separation of non-reporter kinase from reporter kinase using gel filtration or size exclusion chromatography. In one embodiment, the reporter kinase has a lower molecular weight than the non-reporter kinase. In another embodiment, the reporter kinase has a higher molecular weight than the non-reporter kinase. By way of example, the reporter kinase may have a molecular weight of at least 40 to 80 kDa, whereas the non-reporter kinase may have a molecular weight of no more than 30 kDa. When run through a size exclusion resin or membrane, this provides very efficient separation with the larger protein (eg. the reporter kinase) running at or near the void volume of the matrix (hence running quickly) whilst the non-reporter kinase (eg. endogenous kinase such as mammalian tissue kinase) interacts with the pores of the matrix and elutes more slowly. Suitable “higher molecular weight” reporter kinases may be obtained from Archael sources (e.g. trimeric adenylate kinases enzymes from Aracheal sources), which are in the region of 60 kDa in size compared to the 21-22 kDa of contaminating non-reporter kinase (eg. endogenous kinase such as mammalian tissue kinase). In addition, the size differential between the reporter and non-reporter kinase may be enhanced by the addition of a protein or antibody fragment (e.g. a single chain antibody variable region (scFv), by either chemical conjugation or genetic fusion and recombinant expression) to the reporter kinase. For example, a trimeric adenylate kinase fused to a single chain antibody variable region (scFv) has a size in the order of 120 kDa (based on an scFv size of approximately 20 kDa, attached to each of the three subunits).
In a further embodiment, separation of non-reporter kinase from reporter kinase can be achieved by the use of surface charge. In one embodiment, the isoelectric point of the reporter kinase may be lower than that of the non-reporter kinase. In another embodiment, the isoelectric point of the reporter kinase may be higher than that of the non-reporter kinase. As such, the reporter kinase can be separated from the non-reporter kinases with selective binding of either the reporter kinase or the non-reporter kinase to a cation exchange matrix or anion exchange matrix at a suitable pH. The isoelectric point of reporter kinase is frequently in the high basic range; e.g. the tAK from S. acidocaldarius has a predicted pI of 9.03 (although the inventors have demonstrated that the actual pI is in excess of pH10—see Table 2). By contrast, the majority of non-reporter kinases that could interfere with the assay typically have a lower isoelectric point, e.g. a pI in the region of pH7. As such, the reporter kinase can be separated from the non-reporter kinases with selective binding of the reporter kinase, by the use of either a cation exchange resin, membrane or other solid matrix at a pH of at least 8, or using an anion exchange resin, membrane or other solid matrix above pH10. Many of the reporter kinases of the invention retain enzymatic activity in this pH range. Alternatively, non-reporter kinases can be selectively removed by binding them to suitable matrices, e.g. an anion exchange matrix up to pH9.
In another embodiment of the invention, non-reporter kinase can be separated from reporter kinase using a “hydrophobic capture” technique. Reporter kinases (eg. those from the Sulfolubus family, and related Sulfolobaceae families such as acidianus, metallosphaera, stygiolobus, and sulfurisphaera) show exceptionally tight binding to a variety of surfaces, even when such surfaces are pre-treated or pre-coated (termed “blocked”) with other proteins or detergent-based blocking agents. In contrast, the “blocking” of surfaces substantially prevents the binding of non-reporter kinases (eg. mammalian, fungal and/or plant non-reporter kinases). This difference in physical binding properties allows for an effective separation of reporter kinase from contaminating non-reporter kinases by adherence onto a surface, with the measurement of the reporter kinase being made on that surface after capture. For example, use of a polypropylene of polycarbonate surface) coated with either of the commonly used blocking agents bovine serum albumen (eg. BSA; 3% w/v in neutral buffer) or skimmed milk (eg. 5% w/v in neutral buffer) will completely prevent the binding of non-reporter kinases (eg. endogenous kinases such as mammalian tissue kinases) but not reporter kinase. In this regard, the trimeric reporter kinases such as those derived from S. acidocaldarius, S. solfataricus and related genera are particularly adherent in these circumstances.
One or more of the above treatments for removing/inactivating non-reporter kinase can be combined to achieve or enhance the desired effect. This may mean that the relative concentrations of one or more of the chemical components may be reduced in the presence of second component. For example, the level of urea required to inactivate non-reporter kinase may be around 2M on its own but can be reduced to 1M in the presence of 0.5% SDS, as they both exert an effect on the target molecule.
Some of the above treatments may also have other beneficial effects in clarifying samples being processed and providing greater access to molecules to be detected. In this regard, a preferred application of the present invention is the detection of a microbial infection in a biological sample. Accordingly, the present application provides a sensitive and rapid point-of-care microbial assay. The invention is particularly suited to the rapid detection of bacterial, viral and/or fungal infections in biological samples, such as the microbial sources under ‘reporter kinase’ in Table 1. Additional microbial infections include those described in the Examples, such as hepatitis species, measles species, norovirus species, legionella species, chlamydia species, listeria species, salmonella species, and burkholderia species. The present invention facilitates the detection of microorganisms in stool samples (for example, by the addition of urea and SDS), both in terms of more uniform samples and in the release of the microbial antigens from dumps or aggregates. Similarly, the addition of sodium hypochlorite to a stool sample may simultaneously sterilise the sample (minimising the chance of infections) and reduce the activity of the non-reporter kinase.
The precise order/timing of the steps for removing non-reporter kinase is not critical, provided that these steps are carried out before the reporter kinase comes into contact with ADP. Thus, they can be carried out in the sample preparation phase, or during the assay before the reporter kinase comes into contact with ADP. In one embodiment, the treatment is instead of, or in addition to, a washing step.

As mentioned above, the presence of endogenous ATP may adversely affect the accuracy sensitivity of the assay of the present invention. Thus, in one embodiment, any ATP present prior to addition of ADP is optionally removed using one or more of the treatment steps described below. These treatments may be used in any number (preferably one or more, or at least two, or at least three) and/or in any combination. In all cases, however, the treatment leaves the reporter kinase substantially intact. The treatment steps can be applied to any aspect of the invention.
In one embodiment, the removal of endogenous ATP is achieved using an ATPase (e.g. apyrase). The ATPase may then be removed and/or inactivated before the contact with ADP, to avoid the presence of the ATPase adversely influencing the signal obtained using the reporter kinase. By way of example, an ATPase can be used to remove ATP and then the ATPase is itself destroyed by use of elevated temperature. Alternatively, the ATPase can be immobilised on a device (such as a lateral flow device or filtration device described elsewhere in this specification), such that when ATP flows over the ATPase, the ATP is inactivated. As above, this inactivation step must occur before the reporter kinase comes into contact with the ADP.
In a further embodiment, endogenous ATP can be removed by physical means. By way of example, a filtration device can be used, which separates out the ATP on the basis of size in a similar way to that described above for separation of the reporter kinase from non-reporter kinases. Advantageously, the removal of both the ATP and non-reporter kinase can be achieved simultaneously as they are both much smaller than the reporter kinase, either when the latter is on its own or when attached to an antibody, structure or other diagnostic reagent.
In another embodiment, endogenous ATP can be removed on the basis of surface charge as described above. The negative charge of the ATP at pH 5.5 allow it to bind to an anion exchange resin, along with non-reporter kinases, but not the reporter kinase. This again effectively separates the contaminating ATP and non-reporter kinase from the signal-generating reporter kinase in a single step.
The precise order/timing of the steps for removing endogenous ATP is not critical, provided that these steps are carried out before the reporter kinase comes into contact with ADP. Thus, they can be carried out in the sample preparation phase, or during the assay before the reporter kinase comes into contact with ADP. In one embodiment, the treatment is instead of, or in addition to, a washing step.
Data of the type presented in FIG. 3 are helpful when deciding on the type and/or number of background-reduction steps (i.e. removal or inactivation of non-reporter kinase and/or ATP) to use in the assay of a particular sample (although this information does not preclude the use of these steps in any assay type, particularly where infections can influence the background levels of either ATP or reporter kinase).
Any suitable kinase enzyme may be used as the reporter kinase in the present invention. In one embodiment, the reporter kinase is an adenylate kinase, acetate kinase or pyruvate kinase, or a combination thereof.
The reporter kinase used in the invention may have a trimeric or monomeric structure—these tertiary structures are associated with an improved stability of the kinase to conditions such as e.g. temperature, pH, chemical denaturants, or proteases.
In one embodiment, the reporter kinase is a non-mammalian, a non-fungal, and/or a non-plant kinase.
In one embodiment, the reporter kinase is a microbial kinase—suitable kinases include Pyrococcus species kinases such as Pyrococcus furiousus kinase, P. abyssi kinase, furiosus kinase, P. horikoshii kinase, P. woesii kinase; Sulfolobus species kinases such as Sulfolobus solfataricus kinase. S. acidocaldarius kinase, S. shibatae kinase; Rhodothermus species kinases such as Rhodothermus marinus kinase; Thermococcus species kinases such as Thermococcus litoralis kinase; Thermotoga species kinases such as Thermotoga maritima kinase, Thermotoga neapolitana kinase; and Methanococcus species kinases such as M. ruber kinase. In another embodiment, the kinase is an Archeoglobus species kinase such as A. fulgidus kinase; an Aeropyrum species kinase such as A. pernix kinase; an Aquifex species kinase such as A. pyrophilus kinase, an Alicyclobacillus kinase such as A. acidocaldarius kinase; Bacillus species kinase such as B. caldotenax BT1 kinase, a Bacillus species PS3 kinase, B. stearothermophilus 11057 kinase, B. stearothermophilus 12001 kinase, B. thermocatenulatus kinase; a clostridial species kinase such as C. stercocorarium kinase; a Thermoanaerobacter species kinase such as T. ethanolicus kinase, T. thermosulfurogenes kinase, T. celere kinase. T. aquaticus YT1 kinase, T. caldophilus GK24 kinase, T. thermophilus HB8 kinase. In preferred embodiment, the kinase is a T. litoralis kinase, T. maritima kinase, or a T. neapolitana kinase.
In one embodiment, the reporter kinase is thermostable. As well as being resistant to high temperatures, thermostable kinases are also found to be resistant to other biochemical and physical processes that routinely damage or destroy proteins or render them inactive, such as exposure to certain chemicals e.g. chaotropes, free-radical damage, detergents, extremes of pH, exposure to proteases, protein cross-linking, encapsulation within non-permeable or semi-permeable membranes or polymers, or irreversible immobilisation onto surfaces, (See for example: Daniel R M, Cowan D A, Morgan H W, Curran M P, “A correlation between protein thermostability and resistance to proteolysis”, Biochem J. 1982 207:641-4; Rees D C, Robertson A D, “Some thermodynamic implications for the thermostability of proteins”, Protein Sci. 2001 10:1187-94; Burdette D S, Tchernajencko V V, Zeikus J G, “Effect of thermal and chemical denaturants on Thermoanaerobacter ethanolicus secondary-alcohol dehydrogenase stability and activity”, Enzyme Microb Technol. 2000 27:11-18; Scandurra R, Consalvi V, Chiaraluce R, Politi L, Engel P C., “Protein thermostability in extremophiles”, Biochimie. 1998 November; 80(11):933-41; and Liao H H., “Thermostable mutants of kanamycin nucleotidyltransferase are also more stable to proteinase K, urea, detergents, and water-miscible organic solvents”, Enzyme Microb Technol. 1993 April; 15(4):286-92, all of which are hereby incorporated by reference in theft entirety).
In another embodiment, the reporter kinase may be an E. coli kinase, Clostridium difficile kinase, Bacillus anthracis kinase, Acinetobacter baumanii kinase, Burkholderia pseudomallei kinase, Chlamydia trachomatis kinase, Chlamydia pneumonia kinase, Staphylococcus aureus kinase, Klebsiella pneumonia kinase. Rickettsia prowazekii kinase, Mycobacterium tuberculosis kinase, Saccharomyces cerevisiae kinase, Leishmania donovanii kinase, Trypanosome cruzii kinase, Shigella flexneri kinase, Listeria monocytogenes kinase, Plasmodium falciparum kinase, Mycobacterium marinum kinase, Cryptococcus neoformans kinase. Francisella tulraensis kinase, Salmonella spp. kinase, Coxiella burnetii kinase, and/or Brucella abortus kinase, In several of the embodiments, the kinase derived from these organisms is non-thermostable, but can be distinguished from non-reporter kinase by the use of different sample treatment, extraction or separation techniques. Many of these reporter kinases, in combination with the method to distinguish their activity from non-reporter kinases, may be used in rapid assays to detect the presence/absence, viability or destruction of the organism from which they originate. Such methods are suitable for assessing the presence of an infection within patient sample, tissue or cell population and the effectiveness of different therapeutic regimes or drugs.
Examples of specific kinases that have been sequenced and that are suitable for use in the invention are SEQ ID NOs 1-25, 31-36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, and 61-84. In one embodiment, the kinases used in the invention have at least 70%, 80%, 85%, 90%, 95%, 99% or 100% identity to SEQ ID Nos: 1-25, 31-36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, and 61-84.
Other examples of suitable reporter kinases may be found in WO00/46357 and WO2005/093085, which are hereby incorporated by reference in their entirety.
The stability of the reporter kinases may be increased using a variety of methods well-known to those familiar with the art.
By way of example, stabilising agents (such as sorbitol up to a concentration of 4M, or other polyols such as ethylene glycol, glycerol, or mannitol at a concentration of up to 2M) may improve the stability of the kinase. Other additives such as xylan, trehalose, gelatin may also provide additional stabilisation effects either individually or in combination. Addition of a range of divalent metal ions, most notably Ca2+, Mg2+ or Mn2+ may also improve stability of the kinase.
Chemical modification of the kinases can also be used to improve their stability. Reductive alkylation of surface exposed amino groups by glyoxylic acid (e.g Melik-Nubarov (1987) Biotech letts 9:725-730), addition of carbohydrates to the protein surface (e.g. Klibanov (1979) Anal. Biochem. 93:1-25) and amidation (e.g. Klibanov (1983) Adv. Appl. Microbiol. 29:1-28) may all increase the stability of the kinase. Further methods including the use of chemical cross-linking agents and the use of various polymeric supports for enzyme immobilisation are also relevant methods for increasing the stability of enzymes (reviewed in Gupta (1991) Biotech. Appl. Biochem. 14:1-11).
Formulation of the kinase, in a solution containing up to around 10 mg/ml of a suitable carrier protein such as casein or albumin, or the addition of free amino acids such as glycine, tyrosine, tryptophan or dipeptides to the formulation, may increase the stability of the kinase to protease treatments.
The genetic modification of enzymes has been shown to provide significant increases in thermal stability and by analogy such mutations are also likely to significantly enhance the stability of the enzymes to other conditions such as protease treatment or gaseous phase “sterilisation”. The comparison of the thermostability of the kinase enzymes taken with the defined 3-D structure of the trimeric (archaeal) AKs (Vonrhein et al (1998) J. Mol. Biol. 282:167-179 and Criswell et al (2003) J. Mol. Biol. 330:1087-1099) has identified amino acids that influence the stability of the enzyme.
Genetically engineered variants of kinases showing improved stability can be generated in a number of ways. Essentially these involve the specific site-directed mutagenesis of amino acids believed to form part of the central core packing region of the trimeric molecule and random “directed evolution” methods where the whole molecule is subjected to subsequent rounds of mutagenesis and selection/screening of molecules with improved properties. Specific modified enzymes are set out in SEQ ID NOs: 17-19 (several variants are embraced by each reference). These modifications outlined are based on a hybrid approach using a consensus based approach to define regions likely to influence the thermostability of the enzymes based on observed differences between structurally related molecules. This is followed by either defined changes to incorporate the amino acids that correlate with the best thermostability or a random replacement to incorporate every available amino acid at the positions defined as being essential for thermostability.
In one embodiment of the invention, the reporter kinases may be bound onto a solid support.
Suitable solid supports include a plastic (e.g. polycarbonate, polystyrene or polypropylene) surface, a ceramic surface, a latex surface, a magnetic surface, a steel or other metallic surface, a flow matrix (as described elsewhere in this specification), a filter membrane, or other polymer surface. The solid support can take the form of e.g. strips, dipsticks, microtitre plates, beads.
Binding of the reporter kinase to the solid support may be achieved using any of a wide variety of methods known in the art.
In one embodiment, the reporter kinase is bound onto the solid support via standard protein adsorption methods, such as outlined below.
Binding of the reporter kinase onto the solid support may be achieved by methods routinely used to link protein to surfaces, e.g. incubation of protein in 0.1M sodium bicarbonate buffer at about pH 9.6 at room temperature for about 1 hour. Alternatively the protein is covalently coupled to the surface using any of a wide range of coupling chemistries known to those familiar with the art. For example an adenylate kinase fusion protein (e.g. to Sup35) derivatised with SPDP (Pierce chemicals; using manufacturer's instructions), reduced with DTT to provide free sulfhydryl groups for cross-linking, is covalently attached to a polystyrene support with a maleimide surface. Plastic surfaces with such sulfhydryl-binding surfaces are well described in the literature. The reporter kinases described in this application have the property that their activity is retained upon derivatisation and cross-linking to such supports.
Alternatively an amine reactive surface on a polystyrene or polycarbonate support is used, with a bifunctional cross-linking agent such as monomeric glutaraldehyde, to provide direct non-cleavable cross-linking of the kinase via free amine groups on the protein. UV treatment can also be used to directly link the indicator to a suitable support. Steel surfaces can be treated in a similar way to plastic surfaces to mediate covalent attachment of the kinase.
A wide variety of protein cross-linking reagents is available from companies such as Pierce chemical company (Perbio). Reagents reactive to sulfhydryl, amino, hydroxyl and carboxyl groups are designed for coupling proteins but they can equally be used for cross-linking proteins to either naturally reactive or coated solid supports such as plastics, other polymers, glass and metals. Reactive chemistries are also available for cross-linking the enzymes to carbohydrates. For example, the reagents BMPH ((N-[β-Maleimidopropionic acid]hydrazide.TFA), KMUH ((N-[k-Maleimidoundecanoic acid]hydrazide), and MPBH (4-(4-N-Maleimidophenyl)butyric acid hydrazide hydrochloride) can be used to cross link the indicator containing either a free sulfhydryl in the form of a cysteine residue or a chemically derivatised protein reduced to generate a sulfhydryl reactive group, to carbohydrates. This may be particularly important for a solid support which is either a complex carbohydrate (e.g. paper, cellulose-based membranes, gels or resins) or can be coated or treated with a carbohydrate solution to generate a suitably reactive surface.
For each type of support the reporter kinase may be formulated in a solution that enhances binding and/or stabilises the bound protein. Such formulations include solutions containing up to 10% (w/v) sucrose, sorbitol, mannitol, cellulose, or polyethylene glycol (PEG). In addition the kinase can be formulated as part of a gel that is applied to the surface or lumen of a suitable support. Examples include alginate, agar or polyacrylamide matrices.
In another embodiment, the reporter kinase may be attached to a solid support via a linker that comprises a binding agent specific for an analyte. Details of suitable methods for achieving this attachment are given elsewhere in this specification.
The assay described in the first aspect of the invention is particularly suitable for detecting kinase activity in kinase-based analyte detection assays such as those described in the applicant's earlier filing, WO00/46357, the entirety of which is hereby incorporated by reference.
Thus, in a second aspect of the invention, there is provided a method for determining the presence of an analyte in a sample, comprising:
(i) exposing the sample to a reporter kinase coupled to a binding agent specific for the analyte, so that a complex is formed between the reporter kinase and any analyte present in the sample:
(ii) separating complexed reporter kinase from uncomplexed reporter kinase; and
(iii) measuring the activity of the complexed reporter kinase using an assay according to the first aspect of the invention.
The binding agent used in this method (and in any other method described in this specification) is typically an antibody (or a fragment thereof) that binds specifically to the analyte under investigation. The antibody may be obtained using conventional techniques for identification and isolation of specific antibodies, and the assay is thus of application to substantially all analytes against which an antibody can be raised. Alternatively, the binding agent may be selected from the group consisting of lectins, growth factors, DNA/RNA aptamers, phage or other species that bind specifically to the analyte under investigation. Where a first and second binding agent are involved, these binding agents may be the same or different.
The reporter kinase may be coupled to the specific binding agent by conventional techniques. For example, there are numerous ways of labelling immunoreactive biomolecules with enzymes (conjugation). Antibodies, the majority of antigens, and enzymes are all proteins and, therefore, general methods of protein covalent cross-linking can be adapted to the production of immunoassay reagents. The preparation of antibody-enzyme conjugates requires mild conditions to ensure the retention of both the immunological properties of the antibody and the catalytic properties of the enzyme. Common methods include, glutaraldehyde coupling, the use of periodate oxidation of glycoproteins to generate dialdehydes capable of forming Schiff-base linkages with free amino groups on other protein molecules, and the use of heterobifunctional reagents, for example, succinimidyl-4-(N-maleimidomethyl)cyclohexane-1-carboxylate (SMCC).
In one embodiment of the invention, the above method is a performed as a “capture assay”, such as a sandwich assay (sometimes referred to as a two antibody capture assay), an antigen capture assay, or an antibody capture assay. In an example of an antibody capture assay, an analyte is first bound to a solid support, by e.g. non-specific binding. The analyte is then exposed to a reporter kinase linked to a binding agent (e.g. an antibody) specific for the analyte. A complex is thus formed between the analyte and the reporter kinase. Any uncomplexed reporter kinase is removed by one or more routine washing steps. ADP and luciferin/luciferase are then added to the solid support where the ADP is converted to ATP by the reporter kinase complex. The luciferin/luciferase converts the ATP to a light output, which can then be measured and correlated to the amount of analyte present on the solid support.
In one embodiment, at any point prior to step (iii), the sample is treated to remove/inactivate non-reporter kinase and/or ATP. Suitable treatments that may be employed in this regard are described earner in this specification.
In one embodiment, the method described in this aspect of the invention is completed within less than 15 minutes, less than 10 minute, less than 5 minutes, or less than 2 minutes.
Example 10 describes the use of a method according this aspect of the invention to detect the presence of Hepatitis C in an or swab sample. An oral swab sample is taken from the mouth of a patient and dried in an oven at 90 C for 1 minute to remove any non-reporter kinase (eg. endogenous kinase such as mammalian tissue kinase). The swab is then exposed to a conjugate comprising a reporter kinase coupled to an antibody for Hepatitis C antigen. The reporter kinase conjugate forms a complex with any Hepatitis C antigen present on the swab sample. The swab is then rinsed to remove any uncomplexed reporter kinase conjugate, and is inserted into a reagent tube containing ADP and luciferin and luciferase. The reagent tube is transferred to a hand-held luminometer and the light output is measured. The light output can then be correlated with the amount of analyte present in the sample.
In a third aspect, the invention provides a method for determining the presence of an analyte in a sample, comprising:
(i) providing a solid support comprising a reporter kinase, wherein the reporter kinase is attached to the solid support via a linker that comprises a binding agent specific for the analyte;
(ii) applying the sample to the solid support, whereby any analyte present in the sample displaces reporter kinase from the solid support; and
(iii) measuring the activity of the displaced reporter kinase using an assay according to the first aspect of the invention.
In one embodiment, the method described in this aspect of the invention is completed within less than 15 minutes, less than 10 minutes, less than 5 minutes, or less than 2 minutes.
By way of example, a clinical sample is provided that is suspected to contain a bacterial toxin. A solid support is also provided, which comprises a reporter kinase linked to the solid support by a binding agent (e.g. an antibody) that is specific for the bacterial toxin. When the sample is applied to the solid support, any bacterial toxin present will competitively interfere with the binding of the antibody to the solid support and will thereby displace the reporter kinase from the solid support. The amount of displaced reporter kinase can then be measured using an assay according to the first aspect of the invention and correlated with the amount of bacterial toxin present in the sample.
Example 13 describes the use of this method to detect the presence of norovirus in a clinical sample. In this example, the solid support is coated with an antibody to norovirus (i.e. a binding agent specific for the analyte). A reporter kinase conjugate is formed comprising a reporter kinase conjugated to a VP1 norovirus protein (i.e. the analyte). By virtue of the interaction between the VP1 and the antibody, the reporter kinase attached to the solid support. The clinical sample is then applied to the solid support. Any norovirus (i.e. analyte) present in the sample displaces the reporter kinase conjugate from the solid support. The activity of this displaced reporter kinase is then measured and correlated with the amount of norovirus present in the sample.
In one embodiment, the solid support is a flow matrix. The term “flow matrix” is used throughout this specification to mean any liquid-transport solid material that allows for liquid flow therethrough, including materials such as nitrocellulose, nylon, rayon, cellulose, paper, glass fibre, silica, a gel matrix, or any other porous or fibrous materials. In one embodiment, the flow matrix is configured as a substantially planar elongate strip. The flow matrix material can be pre-treated or modified as required.
Suitable methods for attaching the reporter kinase to the solid support are described below. The binding agent is as defined above in relation to the second aspect of the invention.

    
    
        An analyte is coupled directly to the surface of the solid support.
         The reporter kinase is linked to a binding agent specific for the analyte (e.g. an antibody) and thereby associates with the analyte on the surface. The reporter kinase remains attached to the surface until displaced by the presence of either antibody or analyte in the sample.
        An analyte is bound to the solid support via a first binding agent specific for the analyte.
         The reporter kinase is conjugated to a second binding agent specific for the analyte and thereby associates with the analyte on the surface. The reporter kinase remains attached to the surface (in a sandwich-type arrangement) until displaced by the presence of either antibody or analyte in the sample.
        A binding agent specific to the analyte is used to coat the solid support.
         The reporter kinase is conjugated or genetically fused to the target analyte and thereby associates with the binding agent on the surface. The reporter kinase-analyte conjugate is released from the solid support by competing analyte or antibody in the test sample.
    
    


The reporter kinase is therefore indirectly attached to the solid support by a linker that comprises a binding agent specific for the analyte. The linker may also comprise the analyte for a fragment thereof).
In one embodiment, at any point prior to step (iii), the sample is treated to remove/inactivate non-reporter kinase and/or ATP. Suitable treatments are described elsewhere in this specification.
In a fourth aspect, the invention provides a method for determining the presence of an analyte in a sample, comprising:
(i) providing a solid support on which is attached a first binding agent specific for the analyte;
(ii) exposing the solid support to the sample so that any analyte present in the sample becomes attached to the solid support via said first binding agent;
(iii) exposing the solid support to a reporter kinase coupled to a second binding agent specific for the analyte, so that the reporter kinase becomes attached to the solid support via the interaction between the second binding agent and the already-bound analyte;

(iv) applying the mixture obtained in step (iii) to a filter membrane, wherein the solid support is retained on the filter membrane; and

(v) measuring the activity of the retained reporter kinase using an assay according to the first aspect of the invention.

In one embodiment, the method described above is completed within less than 15 minutes, less than 10 minutes, less than 5 minutes, or less than 2 minutes.
In one embodiment, the solid support is a latex support, or a magnetic support, e.g. a latex bead or a magnetic bead. When the solid support is magnetic, step (iv) may be replaced by exposing the mixture obtained in step (iii) to a magnet, so that the solid support is retained on the magnet.
Example 14 describes the use of this method for detecting the presence of legionella in a water sample. Antibodies specific for legionella are attached to a solid support (a latex bead). The latex beads are then exposed to (i) the sample to be tested (potentially containing legionella) and (ii) a reporter kinase coupled to a second antibody specific for legionella. Any legionella present in the sample binds to the antibody on the latex bead. Subsequently, the reporter kinase-antibody conjugate binds to the latex bead via the already-bound legionella. The mixture thus obtained is applied to a filter membrane, which retains the latex beads. The other components of the mixture (e.g. unbound reporter kinase conjugate, ATP, non-reporter kinase (eg. mammalian tissue kinase, plant and/or fungal kinase endogenous to the test sample etc.) pass through the filter membrane. The reporter kinase retained on the filter membrane is then exposed to ADP and a mixture luciferin/luciferase, and the light output measured using a luminometer. Optionally, the filter membrane can be treated using any of the treatment steps described above for removing any remaining ATP or non-reporter kinase.
Suitable filter membranes for use in this aspect of the invention include: nitrocellulose, cellulose acetate or paper filters. Filter matrices typically employ a range of pore sizes from 0.2 μm to 20 μm or larger depending on the nature of any particulate carrier used.
Example 17 describes the use of this method for detecting the presence of Salmonella in a food sample. The method is essentially as described for Example 14 above, except that a magnetic head is used as the solid support instead of a latex bead, and the mixture obtained in step (iii) is exposed to a magnet rather than a filter membrane.
In one embodiment, at any point prior to step (v), the sample is treated to remove or inactivate non-reporter kinase and/or ATP. Suitable treatments are described elsewhere in this specification.
The assay described in the first aspect of the invention is also suitable for detecting kinase activity in kinase-based biological indicator systems such as those described in the applicant's earlier filing, WO2005/093085, which is hereby incorporated by reference in its entirety.
A typical biological indicator is prepared by adsorbing a reporter kinase onto a solid support such as an indicator strip or dipstick. The indicator is then included with a sample (containing a contaminant) to be treated, and the indicator plus sample are subjected to a treatment process. The reduction in activity of the indicator kinase by the treatment is then correlated with the reduction in amount or activity of the contaminant. When a level of activity is determined that is known to correlate with an acceptable reduction in the contaminant, the treatment is then regarded as validated.
It has also been found that the performance of these kinase-based indicators can be improved by covalently cross-linking the kinase to a biological component, wherein the biological component is a mimetic/surrogate of the contaminant. This allows the indicator to more accurately reflect the reaction of the contaminant to the treatment process, which in turn leads to improved indicator accuracy/sensitivity, and thus fewer “false” process validations.
Thus, in a fifth aspect of the invention, there is provided a method of validating a treatment process for reducing the amount or activity of a contaminating biological agent in a sample, comprising the steps of:
(i) providing a sample that contains, or is suspected to contain, a contaminating biological agent;
(ii) subjecting the sample to a treatment process in the presence of a defined amount of a reporter kinase, wherein the reporter kinase and the contaminating biological agent are both exposed to the treatment process;
(iii) measuring the residual activity of the reporter kinase using an assay according to the first aspect of the invention; and
(iv) comparing said residual activity to a predetermined kinase activity, wherein the pre-determined kinase activity corresponds to a confirmed reduction in the amount or activity of the contaminating biological agent under the same conditions.
In one embodiment, steps (i) to (iv) are completed in less than 15 minutes, less than 10 minutes, less than 5 minutes, less than 2 minutes.
In one embodiment, at any point prior to step (iii), the sample is treated to remove/inactivate non-reporter kinase and/or ATP. Suitable treatments are described elsewhere in this specification.
The term “treatment” or “treatment process” encompasses any process that is designed to reduce the amount or activity of a contaminant in a sample. Suitable treatments include one or more of; a selected pH, temperature or pressure, exposing the sample to a protease or other lytic enzyme, exposing the sample to a detergent, a chemical sterilant, radiation, free radicals, or a gas-phase sterilant. In one embodiment, the treatment is designed to reduce the infectious activity (also known as the infectivity) of an infectious biological contaminant, such as TSE. The term “treatment” or “treatment process” also encompasses cleaning and inactivation processes such as high temperature autoclaving with wet or dry steam, ozone sterilisation. H2O2 sterilisation, rendering or other method designed to eliminate or inactivate the contaminant. In one embodiment of the invention, both the reporter kinase and the contaminant are directly exposed to the treatment process, i.e. there is no seal or barrier between the reporter kinase/contaminant and the treatment process. The reporter kinase and the contaminant are therefore both in direct contact with the treatment process, and are subject to the same treatment conditions.
In one embodiment, the contaminating biological agent is selected from the group consisting of bacteria, viruses, spores, toxins, prions, proteins and peptides. In a further embodiment, the reporter kinase is bound onto a solid support using any of the methods described in relation to the first aspect of the invention.
In another embodiment of the invention, the reporter kinase is covalently linked to a biological component.
The biological component is advantageously a mimetic or surrogate of the contaminant, and therefore reacts to the treatment process in substantially the same way as the contaminant. In one embodiment, the biological component may be the same as, but physically distinct from, the contaminant in the sample that is to be subjected to the treatment process, e.g. if the contaminant is a protein, then the biological component is also a protein; if the contaminant is a blood protein, the biological component is also blood protein; if the contaminant is a DNA molecule, then the biological component is also a DNA molecule; if the contaminant is an RNA molecule then the biological component is also an RNA molecule, etc. for each of the contaminants and biological components disclosed in this specification.
Examples of biological components that can be used in the invention include proteins, nucleic acids, carbohydrates and lipids.
In one embodiment, the biological component comprises a protein selected from the group consisting of a blood protein, a bacterial protein, a viral protein, a fungal protein, and a self-aggregating or amyloid forming protein.

In a further embodiment, the fungal protein is selected from the group consisting of hydrophobin proteins (e.g. SC3 from Schizophyllum commune, RodA/B from Aspergillus fumigates, and equivalent proteins from yeast), fungal spore proteins, hyphal proteins, mycotoxins, and fungal prions (e.g. Sup35, Het S, URE 2, Rnq1, New 1).
In yet a further embodiment, the self-aggregating protein is selected from the group consisting of prions (e.g. PrPSc and PrPc, Sup35, Het S, Ure 2, Rnq1, New 1), prion mimetic proteins, amyloid fibrils, cell surface adhesins from floc forming and filamentous bacteria in activated sludge, beta amyloid protein, tau protein, polyadenine binding protein, herpes simplex virus glycoprotein B, lung surfactant protein C, CsgA protein from E. coli, AgfA protein from Salmonella species, bacterial fimbrial proteins, apolipoproteins (e.g. apolipoprotein A1), hydrophobias from fungal species (e.g. SC3 from Schizophyllum commune, RodA/B from Aspergillus fumigates), chaplins (e.g. Chps A-H from streptomyces spp), rodlins (e.g. Rd1A and Rd1B from streptomyces spp), gram positive spore coat proteins (e.g. P29a, P29b, GP85 and a SpoVM analogue), and barnacle cement-like proteins (e.g. the 19 kDa protein from Balanus albicostatus, and the 20 kDa protein from Megabalanus rosa, and the novel calcite-dependent cement-like protein from Balanus albicostatus).
In a further embodiment, the nucleic add is selected from a DNA molecule and an RNA molecule. Preferably, the nucleic acid is derived from neurological tissue.
In a further embodiment, the carbohydrate is selected from the group consisting of exopolysaccharide, lipopolysaccharide (EPS/LPS, sometimes known as endotoxin) (e.g. from Legionella, E. coli, Staphylococcus species, Streptococcus species, Pseudomonas species, Acinetobactor species, Campylobactor species, and Bacillus species), peptidoglycan, cell wall components of plants, fungi and yeast (e.g. chitin, lignin, glucan), mucin preparations, glycolipids (especially brain derived glycolipids), glycoproteins (e.g. cell surface glycoproteins, Eap1p), spore extracts (e.g. from Bacillus spp, Clostridial spp and other spore-formers), polysaccharides from yeast capsules, and invertebrate secretions (e.g. from molluscan gels).
In another embodiment, the lipid is selected from the group consisting of glycolipids (e.g. brain-derived glycolipids), gangliosides (e.g. neuronal cell gangliosides such as GT1b, GT1a and gangliosides of more general cell origin such as GM1), and plant oils and lipids.
Advantageously, the biological component is part of a biological matrix. The biological matrix may be a mimetic of the sample that is to be treated. In one embodiment, the biological matrix comprises one or more components selected from the group consisting of proteins, lipids, nucleic acids, and carbohydrates, or fragments or derivatives thereof. In another embodiment, the biological matrix may comprise a mixture of proteins. In a further embodiment, the biological matrix may comprise one or more components selected from the group consisting of blood, serum, albumin, mucus, egg, neurological tissue, food, culled animal material, and a commercially available test soil. In a further embodiment of the invention, the biological matrix comprises one or more components selected from the group consisting of fibrinogen, thrombin, factor VIII, CaCl2, and, optionally, albumin and/or haemoglobin. Examples of reporter kinases, linked to biological components are described in SEQ ID NOs: 34-38, 40, 42, 48, 50, 52, 54, 61, 67, 72, and 73.
The biological indicator may be prepared by covalently linking a reporter kinase to an appropriate biological component. Any suitable method of covalent attachment known in the art may be used. In one embodiment, the kinase is genetically or chemically cross-linked to the biological component.
Chemical cross-linking may be achieved using a range of homo- and hetero-bifunctional reagents commonly used for cross-linking of proteins for the generation of enzyme conjugates or other related purposes. For example, in an indicator comprising fibrin as the biological component, the fibrin and the reporter kinase may be derivatised with the addition of SPDP (Perbio) to primary amine groups. The reporter kinase can then be reduced to generate a reactive thiol group and this is then mixed with the fibrin to produce covalent fibrin-kinase linkages.
The reporter kinases can also be chemically cross-linked to carbohydrates, lipids or other glycoconjugates using heterobifunctional agents following treatment of the target carbohydrate with meta-periodate.
Alternatively, the indicator may be prepared as a fusion protein. This is achieved by fusing a synthetic gene encoding an appropriate kinase (e.g. the gene encoding AK from Sulfolobus acidocaldarius or Thermotoga neapolitana) to a gene encoding an appropriate biological component.
Methods according to this aspect of the invention are illustrated in Examples 18-21.
In a sixth aspect of the invention, there is provided a device for detecting the activity of a reporter kinase in a sample, comprising:
an elongate flow matrix, wherein said flow matrix comprises:
(i) a sample-receiving zone; and
(ii) a detection zone, located downstream of the ample-receiving zone, comprising a mixture of ADP and a bioluminescent reagent;
wherein, in use, a sample is applied to the sample-receiving zone and is drawn along the flow matrix to the detection zone.
In use, the sample is applied to the sample-receiving zone of the device and is allowed to migrate to the detection zone where it comes into contact with the mixture of ADP and bioluminescent reagent. Here, any reporter kinase present in the sample acts on the ADP to generate ATP, which in turn reacts with the bioluminescent reagent to produce light. The light output from the detection zone can be readily measured using a luminometer, preferably a hand-held luminometer. In one embodiment, the detection zone of the device is snapped off and placed in a luminometer. The amount of light produced can then be correlated with the amount of reporter kinase activity.
In one embodiment, the device comprises a hacking strip on which the elongate flow matrix is positioned. The backing strip may be made from any suitable non-absorbing material, such as a plastic-adhesive backing card. In another embodiment, the flow matrix is at least partially sandwiched between a top and a bottom laminate. The top laminate may include a sample-application window, which provides access to the sample-receiving zone of the flow matrix, and may also include a detection window, which provides access to the detection zone of the flow matrix. The laminates may be made from any suitable non-absorbing material, e.g. a transparent or translucent adhesive plastic film.
In one embodiment, the device is a lateral flow device. Lateral flow devices and methods for their construction are well known in the art, being best known as the standard pregnancy test kit.
In a further embodiment, the device may comprise a background-reduction zone, situated between the sample-receiving zone and the detection zone. This zone functions to remove/inactivate any non-reporter kinase and/or ATP that may be present in the sample before the sample reaches the detection zone. Thus, these contaminants are prevented from interfering with the sensitivity or accuracy of the assay.
In one embodiment, the background-reduction removal zone comprises a substance that selectively (or specifically) inhibits non-reporter kinase, whilst leaving the reporter kinase substantially unaffected. Suitable inhibitors are described elsewhere in this specification. In another embodiment, the background-reduction zone comprises a protease that selectively destroys non-reporter kinase, whilst leaving the reporter kinase substantially unaffected. Suitable proteases are described elsewhere in this specification. In a further embodiment, the background-reduction zone may be arranged so as to physically capture out non-reporter kinases on the basis of their size, charge, or binding properties as described elsewhere in this specification. The captured non-reporter kinases are thus prevented from reaching the detection zone.
In another embodiment, the background-reduction zone comprises an immobilised ATPase, e.g. apyrase. In another embodiment, the background-reduction zone may be arranged so as to physically capture out ATP on the basis of its size or charge as described elsewhere in this specification. The captured ATP is thus prevented from reaching the detection zone.
In one embodiment, the ADP in the detection zone of the device is high purity ADP, and the bioluminescent reagent is a mixture of luciferin and luciferase. In another embodiment, the ADP and luciferin/luciferase are immobilised in the detection zone using conventional immobilisation methods.
In a further embodiment, the device is portable.
In a further embodiment, the detection zone may include a cationic membrane that retains and concentrates the reporter kinase conjugate for enhanced detection.
In another embodiment, the sample-receiving zone may include a suitable dye which also migrates to the detection zone, acting as a control for the proper flow of the sample through the device. This positive internal control may also exploit the use of a cation-binding membrane within the detection zone to help retain the dye to provide a clear visual signal.
In a seventh aspect of the invention, there is provided a lateral flow device for use in an assay for detecting the presence of an analyte in a sample, comprising:
a hacking strip on which is positioned an elongate flow matrix, wherein said flow matrix comprises:
(i) a sample-receiving zone comprising a reporter kinase attached to the flow matrix via a linker comprising a binding agent specific for the analyte; and
(ii) a detection zone, located downstream of the sample-receiving zone;
wherein, in use, a sample is applied to the sample-receiving zone and any analyte present in the sample displaces the reporter kinase from the flow matrix and thereby allows the reporter kinase to migrate to the detection zone.
In use, the sample is applied to the sample-receiving zone, and any analyte present in the sample displaces the reporter kinase attached to the sample-receiving zone. Any reporter kinase that is not displaced remains attached to the sample-receiving zone, and this is the case for a sample negative for the presence of the analyte. Thus, only the displaced reporter kinase proceeds to the detection zone where it can be detected and correlated with the amount of analyte present in the sample.
The backing strip of the device may be made from any suitable non-absorbing material, such as a plastic-adhesive backing card. In one embodiment, the flow matrix is at least partially sandwiched between a top and a bottom laminate. The top laminate may include a sample-application window, which provides access to the sample-receiving zone of the flow matrix, and may also include a detection window, which provides access to the detection zone of the flow matrix. The laminates may be made from any suitable non-absorbing material, e.g. a transparent or translucent adhesive plastic film. In a further embodiment, the detection zone comprises a mixture of ADP and a bioluminescent reagent.
The reporter kinase is attached to the flow matrix by a linker comprising a binding agent specific for the analyte. Binding agents and methods for attaching the reporter kinase to the flow matrix are as described in relation to the second aspect of the invention.
In one embodiment, the device may further comprise a background-reduction zone, situated between the sample-receiving zone and the detection zone. This zone functions to remove/inactivate any non-reporter kinase and/or ATP that may be present in the sample before the sample reaches the detection zone. Thus, these contaminants are prevented from interfering with the sensitivity or accuracy of the assay.
In one embodiment, the background-reduction removal zone comprises a substance that selectively (or specifically) inhibits non-reporter kinase, whilst leaving the reporter kinase substantially unaffected. Suitable inhibitors are described elsewhere in this specification. In another embodiment, the background-reduction removal zone comprises a protease that selectively destroys non-reporter kinase, whilst leaving the reporter kinase substantially unaffected. Suitable proteases are described elsewhere in this specification. In a further embodiment, the background-reduction zone may be arranged so as to physically capture out non-reporter kinases on the of theft size, charge, or binding properties as described elsewhere in this specification. The captured non-reporter kinases, are thus prevented from reaching the detection zone.
In another embodiment, the background-reduction zone comprises an immobilised ATPase, e.g. apyrase. In another embodiment, the background-reduction zone may be arranged so as to physically capture out ATP on the basis of its size or charge as described elsewhere in this specification. The captured ATP is thus prevented from reaching the detection zone.
In one embodiment, the ADP in the detection zone of the device is high purity ADP, and the bioluminescent reagent is a mixture of luciferin and luciferase. In another embodiment, the ADP and luciferin/luciferase are immobilised in the detection zone using conventional immobilisation methods.
In another embodiment, the device is portable.
In a further embodiment, the detection zone may include a cationic membrane that retains and concentrates the reporter kinase conjugate for enhanced detection.
In another embodiment, the sample-receiving zone may include a suitable dye which also migrates to the detection zone, acting as a control for the proper flow of the sample through the device. This positive internal control may also exploit the use of a cation-binding membrane within the detection zone to help retain the dye to provide a clear visual signal.
In an eighth aspect, the invention provides a method for detecting the activity of a reporter kinase in a sample, wherein the method is conducted using a device according to the sixth aspect of the invention, comprising the steps of:
(i) applying the sample to the sample-receiving zone of the device;
(ii) allowing the sample to flow through to the detection zone of the device; and
(iii) detecting the light output from the detection zone.
In one embodiment, after step (i), the method further comprises allowing the sample to flow through a background-reduction zone as described in relation to the sixth aspect of the invention.
In another embodiment, step (iii) is cared out by snapping off the detection zone of the device, and then placing the detection zone into a luminometer.
In a further embodiment, the method comprises the step of recording the light output data obtained on a suitable data carrier.
In a ninth aspect of the invention there is provided a method for detecting the presence of an analyte in a sample using the device described in relation to the seventh aspect of the invention comprising:
(i) applying the sample to the sample-receiving zone of the device;
(ii) allowing any reporter kinase displaced from the sample-receiving zone to migrate to the detection zone; and
(iii) detecting the light output from the detection zone.
In one embodiment, after step (i), the method further comprises allowing the sample to flow through a background-reduction zone described in relation to the seventh aspect of the invention.
In another embodiment, step (iii) is carried out by snapping off the detection zone of the device, exposing the detection zone to ADP and a bioluminescent reagent, wherein the detection zone is exposed to the bioluminescent reagent no more than 5 minutes (or no more than 2 minutes, 1 minute, 30 seconds, or 10 seconds) after having been exposed to the ADP, and then placing the detection zone into a luminometer. In one embodiment, the detection zone is exposed to the ADP and bioluminescent reagent simultaneously.
In a further embodiment, the method comprises the step of recording the light output data obtained on a suitable data carrier.
In a tenth aspect, the invention provides a kit comprising a device according to the sixth or seventh aspect of the invention, and a luminometer. In one embodiment, the luminometer is a hand-held (i.e. portable) luminometer.
DEFINITIONS SECTION
The term “light output” means the light that is emitted by the reaction of ATP with the bioluminescent reagent. This light output can be detected using entirely conventional technology, such as a standard luminometer (e.g. a Berthold Orion 96-well microplate luminometer, or a hand-held luminometer).
The term “flow matrix” refers to any liquid-transport solid material that allows for liquid flow therethrough, and includes materials such as nitrocellulose, nylon, rayon, cellulose, paper, glass fibre, silica, gel matrices, or any other porous or fibrous materials, in one embodiment, the flow matrix is configured as a substantially planar elongate strip. The flow matrix material can be pre-treated or modified as required.
The term “reporter kinase” refers to a kinase enzyme that is not a mammalian, plant and/or fungal kinase. Thus, in the context of a biological sample to be tested, a reporter kinase is a kinase that is not normally present (to any significant degree) in a sample taken from a healthy individual. Put another way, a reporter kinase of the present invention is a kinase that is not normally inherent or endogenous (to any significant degree) in a sample taken from a healthy individual. Reporter kinase may be added to the sample as a separate (ie. exogenous) reagent, e.g as an isolated kinase. Reporter kinases are preferably thermostable.
The term “non-reporter kinase” refers to kinase enzyme that is not a reporter kinase as defined above. Non-reporter kinases may also be referred to as endogenous kinases, contaminating kinases, or background kinases. Non-reporter kinases are typically present in a sample taken from a healthy individual. Non-reporter kinase activity can also be defined as activity that is not associated with the reporter kinase. Many non-reporter kinases are derived from mesophilic organisms, i.e. organisms that grow best at moderate temperatures (e.g. 25-40 C). Examples of non-reporter kinases include mammalian, plant and/or fungal kinases—in particular, any of the range of 7 human adenylate kinase isoforms found in varying amounts in clinical samples, equivalent proteins in animal species or food derived from them, or kinases (e.g. adenylate kinases) from common commensal organisms in humans or animals.
The term “thermostable kinase” refers to a kinase that retains activity after exposure to heat, i.e. that is relatively unaffected by high temperatures. Preferred thermostable kinases retain at least 70% activity for 30% activity, 90% activity, 95% activity, or 100% activity) after exposure to a temperature of between 50-120 C. Particularly preferred thermostable kinases retain at least 70% activity (or 80% activity, 90% activity, 95% activity, or 100% activity) after exposure to 50 C for 30 minutes, or after exposure to 60 C for 30 minutes, or after exposure to 70 C for 30 minutes, or after exposure to 80 C for 20 minutes, or after exposure to 90 C for 3 minutes, or after exposure to 120 C for 3 minutes. Thermostable kinases may also be more resistant than non-thermostable kinases to a range of other biochemical and physical processes that routinely damage or destroy proteins or render them inactive, such as exposure to certain chemicals e.g. chaotropes, free-radical damage, detergents, extremes of pH, exposure to proteases, protein cross-linking, encapsulation within non-permeable or semi-permeable membranes or polymers, or irreversible immobilisation onto surfaces. In a particular embodiment, thermostable kinases may retain at least 70% activity (or 80% activity, 90% activity, 95% activity, or 100% activity) after exposure to one or more of the biochemical and physical processes described above. In all cases, this “retained activity” can be readily confirmed using conventional tests. In brief, the kinase is incubated with ADP under the given treatment conditions for a given amount of time, and then analysed for residual activity by detecting the generation of ATP using luciferin/luciferase and a luminometer. From this, the % of kinase activity retained after the treatment can be determined.
The terms “kinase” and “kinase activity” are used interchangeably throughout this specification.
The term “sample” encompasses any item, instrument, surface, fluid or material. Examples include, but are not limited to clinical samples (such as whole blood, serum, oral samples such as saliva, pus, vaginal samples, stool samples, vomitus), environmental samples (such a water, soil, air samples), surgical and medical instruments, microtitre plates, dipsticks, lateral flow devices, hospital gowns, bedclothes, bulk liquids, culled animal material, pharmaceuticals, workbenches, walls and floors, biological matrices, and biological indicators.
The terms “substantially free from non-reporter kinase”, “free from non-reporter kinase”, “substantially free from kinase other than reporter kinase”, and “free from kinase other than reporter kinase” are considered synonymous, and are used interchangeably throughout the specification to mean that the level of non-reporter kinase is sufficiently low or absent and does not interfere to any significant degree with the sensitivity or accuracy of the assay. In terms of assay read-out, the impact of the non-reporter kinase is usually defined in terms of the signal-to-noise ratio. As such, the term “substantially free” can also be defined as meaning that the non-reporter kinase does not account for more than 10% (preferably not more than 5% or 2%) of the total kinase signal at the limit of detection of the assay.
The terms “substantially free from ATP” and “free from ATP” are considered synonymous and are used interchangeably throughout the specification to mean that the level of endogenous ATP is sufficiently low or absent and does not interfere to any significant degree with the sensitivity or accuracy of the assay. Endogenous ATP may have an impact on the assay in terms of signal: noise—thus, the “substantially free” term means that any endogenous ATP accounts for not more than 10% (preferably not more than 5% or 2%) of the total signal at the limit of detection of the assay.
The term “simultaneously” means at the same time. In the context of the first aspect of the invention where, in one embodiment, the reporter kinase is contacted with ADP and bioluminescent reagent simultaneously, this means that there is no (or substantially no) separate incubation period between contacting the kinase with ADP and contacting the kinase with the bioluminescent reagent.
The term “bioluminescent reagent” refers to any substance or mixture of substances able to react with ATP to generate light. A preferred reagent is a mixture of luciferin and luciferase.
The term “RLU” means Relative Light Unit. Relative Light Units are a relative, not absolute, measurement. The figures given in the specification relate to measurements taken using a Berthold Orion 96-well microplate luminometer with injector system using a “flash” method of light measurement for 2 seconds immediately after the addition of the luciferase/luciferin reagents (technical specification photomultiplier measuring light emitted at a wavelength of 300-650 nm). To address this issue, manufacturers have generated data for RLU “factors”, which allow the data generated by a given luminometer to be normalised to a calibrated standard. Thus, comparisons can be made between different instruments. The RLU factor for the Berthold Orion 96-well microplate luminometer is 1. Accordingly, the RLU values given in the specification can be regarded as standardised/normalised RLU values.
In terms of absolute values, an RLU value can be related to the concentration of ATP required to give said value with the reagents as described in the method. As an approximate conversion, and given the linear relationship between RLU values and ATP concentration, the following values can be used:

The invention is now described in specific embodiments in the following examples and with reference to the accompanying drawings in which:
FIG. 1 shows activity of adenylate kinase (AK) enzymes after treatment at 70° C. (A), 80° C. (B) and 90° C. (C);
FIG. 2 shows the stability of a range of AK enzymes recombinantly expressed in E. coli. Genes encoding AK enzymes were cloned and expressed as described in Example 3. All genes were expressed from the vector pET28a except for S. acidocaldarius clone I which was expressed from pET3a as described previously. Expression levels were similar for each done but a proportion of the Pyrococcus furiosus (P. fu) enzyme was in the insoluble fraction and this is likely to have reduced the amount of this enzyme being assayed. The stability of the recombinant enzymes was measured following incubation at 80° C. for 30 minute in a crude E. coli lysate at 10-fold serial dilutions from 1 mg/ml total cellular protein (such that column 12 is equivalent to 1 fg/ml total protein). Enzymes from Thermotoga maritima and Archaeoglobus fulgidus showed significantly greater stability than the other enzymes tested, although the remaining enzymes (Sulfolobus solfataricus (S. so P2), Aeropyrum pernix and P. fu) showed similar activity to the S. acidocaldarius enzyme used as the basis of previous assays (data labelled as S. ac I);
FIGS. 3A & 3B show the relative lever of non-reporter adenylate kinase activity (FIG. 3A) and ATP (FIG. 3B) in a variety of samples relevant to clinical diagnosis. Samples from healthy donors were assessed for the levels of ATP generated by non-reporter adenylate kinase (after addition of ADP as substrate; FIG. 3A) or present naturally in the sample (FIG. 3B). This information can be used to assist in deciding which background reduction steps need to be included in assays for particular samples, although this information does not preclude their use in any assay type, particularly where infections can influence the background levels of either ATP or reporter kinase. Samples are whole blood and sera from sheep, mouse brain homogenate (MBH; representative of tissue biopsy samples), cows' milk, and two saliva samples (1 and 2) collected using either a citric acid (“ca”) method or swab device (“r”). The relative light units generated from the raw assay are converted into ATP units based on a standard curve;
FIGS. 4A & 4B show the differential inhibition of reporter kinase and non-reporter (endogenous) tissue kinase using Ap5a (Diadenosine pentaphosphate pentasodium salt) (FIG. 4A) and the effect of Ap5a on luciferase (FIG. 4B). The reporter adenylate kinases from S. acidocaldarius or T. maritima were purified as described previously. Rabbit myokinase (muscle adenylate kinase) was obtained from Sigma. 100 ng of each enzyme was incubated with the inhibitor at the concentrations shown in reaction buffer (15 mM MgAc, 10 mM tris, 1 mM EDTA pH 7.75) for 5 minutes. ADP was added to a final concentration of 70 μM and the reaction incubated before addition of luciferin and luciferase. The generated following detection with luciferase/luciferin were converted to equivalent ATP units using a standard curve and the results are shown in FIG. 4A. An IC50 (the concentration of inhibitor which reduces the activity of the enzyme by 50%) was calculated and gives values of 10.4 μM (Sac), 4.3 μM (Tma) and 0.06 μM (Rabbit myokinase). The presence of Ap5A does not have a detrimental effect on the activity of the luciferase (see FIG. 48);
FIG. 5 shows the configuration of a lateral flow device for detection of an analyte in a sample;
FIG. 6 shows the configuration of a filtration device for the detection of an analyte in a sample;
FIGS. 7A and 7B show the effects of further inhibitors on the background activity derived from mammalian tissues or samples and/or background from other sources (e.g. yeast contamination). Experiments were carried out essentially as described for FIG. 4. No adverse effect on the activity of luciferase was observed for any of the inhibitors examined (results not shown). Yeast adenylate kinase was obtained from Sigma. FIG. 7A; comparison of inhibition of adenylate kinases by Ap6A, MAK=rabbit muscle AK (myokinase); YAK=yeast AK; SAC=S. acidocaldarius AK; TMA=T. maritima AK. FIG. 7B; comparison of Ap5A and Ap6A for inhibition of contaminating background adenylate kinase from either mammalian cells (MAK) or yeast (YAK). AP4A (not shown) and Ap6A gives similar profiles to Ap5A for differentiating between an example of a monomeric (bacterial) reporter adenylate kinases (from Thermotoga maritima) and an example of a trimeric (archaeal) adenylate kinase from Sulfolobus acidocaldarius when either is compared to a representative example of non-reporter mammalian tissue adenylate kinase (FIG. 7A). Ap4A (not shown) and Ap6A do not allow for an assay to distinguish between the bacterial and Archael enzymes and an enzyme of fungal origin (represented here by the AK from Saccharomyces cerevisiae) (FIG. 7B). In this case Ap5A can still be used to distinguish the reporter adenylate kinases from the yeast enzyme.



EXAMPLE 1
Purification of Native Adenylate Kinase Enzymes
Biomass was produced from twenty-four diverse microorganisms (Table 3).
Eight members of the Archaea were represented along with sixteen diverse aerobic and anaerobic bacteria, AKs from each of these organisms were purified by affinity chromatography using selective absorption and desorption from Cibacron Blue 3A (Blue Sepharose). All enzymes were further characterised and purified by gel filtration (Superdex G200). This enabled identification of the major AK fraction and estimation of molecular mass.

EXAMPLE 2
Analysis of Stability of Native Adenylate Kinases
The stability at 70, 80 and 90° C. of adenylate kinases isolated from biomass from organisms was assessed, and the results shown in FIG. 1.
The adenylate kinases were isolated from the biomass by affinity chromatography using selective absorption and desorption from Cibacron Blue 3A (Blue Sepharose). The samples eluted from the columns were diluted 1:10 000 and then 10 μl of each added to a microtitre well. 2.5 μl of apyrase was added to each well to destroy the ATP present from the elution buffer, and incubated at 37° C. for 30 minutes. The apyrase was inactivated by heat treatment at 65° C. for 20 minutes.
ADP substrate was added and incubated at either 70 (panel A), 80 (panel B) or 90° C. (panel C) for 30 minutes and cooled to 25° C. before the addition of 10 μl of D-luciferin-luciferase reagent. The ATP produced was measured as RLU on a plate luminometer.
EXAMPLE 3
Expression and Purification of Recombinant Adenylate Kinases
Clones expressing representative AKs were secured and recombinant AKs from the archaeon Sulfolobus acidocaldarius and the bacterium, Bacillus stearothermophilus produced. The plasmids were transformed into E. coli and the cell extracts shown to contain protein bands on electrophoresis corresponding to the expected molecular masses of the AKs. AK activity was measured after incubation at the appropriate temperature (80° C. for the Sulfolobus acidocaldarius AK and 60° C. for the Bacillus stearothermophilus AK).
Purification methods for both AKs were established and included an initial heat treatment of incubation for 20 min at 80° C., to inactivate and aggregate proteins derived from E. coli, followed by affinity chromatography and gel filtration. The affinity chromatography involved adsorption of the enzyme to Blue Sepharose, followed by specific elution with a low concentration of AK co-factors (AMP+ATP and magnesium ions). The ATP and AMP (Sigma) in the elution buffer were degraded by incubation with mesophile apyrase, which is readily inactivated by subsequent heat treatment. Gel filtration chromatography was scaled up to utilise a preparation grade Superdex column to enable large quantities of both enzymes to be prepared.
Primers were designed for PCP, amplification of the AK genes from the organisms identified during the screening of candidate native enzymes.
The microorganisms were grown using individually defined growth conditions and genomic DNA isolated and used as templates for PCR amplification of the adenylate kinase genes from each organism. PCP amplified adenylate kinase genes from the organisms, Thermotoga maritima, Aeropyrum pernix, Sulfolobus acidocaldarius and Sulfolobus solfataricus were sub-cloned into the vector, pET28a and transformed into a codon enhanced E. coli strain expressing rare tRNAs (Zdanovsky et al, 2000). This E. coli strain is suitable for enhancing expression levels of AT-rich genes.
The success of the transformation was assessed by a mini-expression study, and the results analysed by SDS-PAGE of the culture supernatants before and after induction with IPTG. SDS-PAGE was also used to analyse the supernatants after inclusion of a heat treatment step, which consisted of heating the sample to 80° C. for 20 minutes prior to running on the SDS-PAGE gel to remove heat labile proteins present in the sample.
EXAMPLE 4
Analysis of the Stability of Recombinant Adenylate Kinases
The stability of recombinant tAK enzymes was assessed in crude E. coli cell lysates.
Cells were grown essentially as described in Example 3 and lysed by sonication. The AK activity of the crude extract was determined both before and after heat treatment at 80° C. for 30 minutes followed by 10-fold serial dilution.
The results (see FIG. 2) demonstrate that a wide variety of recombinant enzymes are suitable for the use in the method of the invention. Particularly preferred AKs are those from T. maritima, A. fulgidus and S. solfataricus. Such enzymes are likely to provide a greater dynamic range for the bioluminescent assay, if required, to provide still further sensitivity.
EXAMPLE 5
Genetic Modification of Adenylate Kinases to Improve Stability
Site-directed mutants were constructed in the AK gene from P. furiosus, P. horikoshii and S. acidocaldarius as shown in Examples 6-8 and SEQ IDs 17-19 respectively, using standard methods known to those familiar with the art.
In addition to specific changes identified in each gene, the regions underlined in the S. acidocaldarius sequence form the core packing region of the archaeal adenylate kinase trimer structure. Hence amino acid substitutions that disturb the packing of this region are likely to have a major effect in decreasing the thermal and physical stability of the enzyme. Conversely amino acid substitutions that improve the core packing, in particular hydrophobic residues with lame side chains, may stabilise the enzyme to heat or other processes. Therefore in addition to the specific mutations already described a number of “selective” approaches were used with localised gene shuffling of related gene sequences in these regions (essentially as described in Stemmer (1994) Nature 370:389-391 and Crameri et al (1996) Nature Biotech, 14:315-319) and random PCR-based mutagenesis using degenerate oligonucleotides or modified nucleotide mixes (e.g. Vartanian et al (1996) Nucleic Acid Res. 24:2627-2633). A number of these modifications show altered stability when assessed by recombinant expression in E. coli and rapid assay of adenylate kinase activity in lysed cells at high temperature.

Mutations at one or more or all of the sites indicated modify the stability of the enzyme. In addition to the three defined changes highlighted, modification of the alanine at position 157 to another small hydrophobic residue (such as I, L) or larger hydrophobic residue (such as F) increases the stability of the recombinant protein. Hence, there are 35 variants possible through combination of modifications at these sites. Modification of amino acid 157 to a polar residue such as the T (as observed at the equivalent position in AdkA of P. horikoshii), S Y, D, E, K, R results in a decrease in stability.

EXAMPLE 10
Detection of Hepatitis C in an Oral Fluid Sample
Antibodies are raised against Hepatitis C surface antigens derived from either structural proteins (e.g. E1 and E2) or non-structural proteins (e.g. NS2, NS3, NS4A, NS4B, NS5A, NS5B) using standard methods. In brief, the proteins are expressed as either recombinant proteins in E. coli, or synthesized as short immunogenic peptides. Short peptides are conjugated to a suitable carrier, such as HLA, and injected intramuscularly into rabbits or guinea pigs at concentrations of approximately 100 μg/ml. Freund's complete adjuvant is used for the first stage of immunization, with incomplete adjuvant used subsequently.
Polyclonal serum is collected after three monthly challenges over a time-course of 3 months. IgG is purified from the blood and conjugated to Tma tAK using standard coupling chemistry. In brief, the antibody is derivatised using SPDP (Pierce Chemical company) at a molar ratio of 3 SPDP to 1 Tma tAK. The free sulfhydryl in the Tma is released by limited treatment with DTT and the protein reacts with the derivatised antibody. The antibody-tAK conjugate is then separated using gel filtration chromatography.
An or crevicular fluid sample is collected using a suitable swab device. The device is heated for 1 minute at 90° C. in a dry oven and then mixed with 1 ml of solution containing the anti-HCV polyclonal antibody-tAK conjugate. The swab is then rinsed in cold water to remove any unbound conjugate and inserted into a reagent tube containing a reagent mix comprising Mg-ADP, luciferin and luciferase. The swab is incubated for 2 minutes and then the entire reagent tube is inserted into a hand-held hygiene monitor and the read-out measured immediately.
EXAMPLE 11
Detection of Immune Status in a Sample of Serum or Whole Blood e.g. Following Immunisation with Measles Vaccine or at an Early Stage Following Exposure to Infectious Measles Virus
A fragment of the measles glycoprotein, other measles virus surface components or heat inactivated measles virus, is used to coat a solid support, such as a dipstick. A sample of whole blood, diluted 1:2 with PBS including up to 2M urea to inactivate any non-reporter kinase is applied to the dipstick and antibodies against the measles components are allowed to bind (binding step 1; 5 minutes at 30° C.). Apyrase is added to the blood sample to inactivate any ATP during this phase. After brief rinsing with phosphate buffered saline (PBS; pH7.4), the dipstick is immersed in a solution containing anti-human IgG conjugated to tAK and incubated (binding step 2; 5 minutes at 30° C.). Again the dipstick is rinsed briefly and then placed within a reagent tube. Luciferin/luciferase and ADP were added simultaneously and the reaction measured using a hand held luminometer after 5 minutes.
EXAMPLE 12
Sample Preparation for Detection of Norovirus in Stool Samples
Norovirus is routinely measured in diarrheal samples (i.e. stool sample) for the purposes of clinical diagnosis.
To reduce the levels of contaminating kinase activity the stool sample is diluted between 1:2 and 1:4 with a buffer designed to inactivate the contaminating kinase. This buffer includes one or more of the following components:
2M urea; 2M guanidine; 1% SDS; 1% deoxycholate; 1% Triton X100
The addition of the above components also makes the norovirus antigen more readily detectable by the antibody conjugates described in the next example, increasing the assay signal as well as reducing assay noise. Optionally, apyrase may also be added to the sample destroy any ATP that may be present.
The same types of additive can also be used as sample processing components for the detection of norovirus in vomitus, a sample which would be useful to test for norovirus but which has not, to date, been suitable for analysis.
EXAMPLE 13
Lateral Flow Essay for the Detection of Norovirus and/or C-Difficile Toxin in a Stool Sample
A reporter kinase conjugate is prepared by conjugating the adenylate kinase from P. abyssi to norovirus VP1 protein or fragments thereof (e.g. the P-domain (located between amino acids 362 and 703), the P2 domain (amino acids 414-589), or sub-fragments of the P1 domain (aa 362-413 or 590-703). The positions within the norovirus correspond to the numbering as described in Chen R, Neill J D, Estes M K, Prasad B V. X-ray structure of a native calicivirus: structural insights into antigenic diversity and host specificity. Proc Natl Acad Sci USA. (2006) 103 p 8048-53.
A lateral flow device is prepared essentially as shown in FIG. 5. The sample-receiving zone is coated with an anti-norovirus antibody or antibodies (to provide detection of the antigenically diverse range of clinical isolates). The reporter kinase conjugate (described above) is then bound to the sample-receiving zone via the antibodies.
The clinical stool sample is processed as outlined in Example 12 above and applied to the sample-receiving zone of the device. In the presence of norovirus, the reporter kinase conjugate is displaced and migrates to the detection zone, via the background-reduction zone. The background-reduction zone comprises an anion exchange membrane which retains any ATP contained within the original sample. By using a buffer at neutral pH (such as PBS) the ATP is retained on the anion exchange membrane whilst the reporter kinase conjugate passes through as it remain below the isoelectric point and is therefore cationic. Non-reporter kinase has previously been removed in the sample preparation phase (see Example 12).
The lateral flow device is then snapped in two and the detection zone is then placed into a reagent tube containing ADP, luciferin and luciferase. The presence of norovirus in the original sample is determined by measurement of light output with an assay time of 2-5 minutes.
Similarly a lateral flow device may be provided to detect the presence of C. difficile toxin A or toxin B in a sample. Antibodies to these targets are well described in the literature and can be conjugated to reporter adenylate kinase(s) as described above. The stool sample is processed as in example 12 and the lateral flow assay carried out as described.
Optionally a device may be provided to detect the presence of either C. difficile toxin(s) or norovirus in a sample, enabling differential diagnosis of clinical samples to be carried out. The sample is processed as described in example 12 and mixed with diagnostic reagents for both norovirus and C. difficile toxin(s) in the same reaction. The sample may be run on two separate lateral flow devices set up to capture only one of the two targets or preferentially on a single device with two capture windows. These two devices or two windows are then assayed separately to determine the presence of one or more of the target species.
EXAMPLE 14
Detection of Legionella in a Water Sample
The assay is carried out using a device as set out in FIG. 6.
A water sample from a cooling tower is sampled at the point of routine maintenance. Typically 50 ml of water is added to a syringe which already contains latex beads coated with anti-legionella antibody (antibody A; or fragment thereof) and the reporter kinase from A. fulgidus chemically conjugated to a second anti-legionella antibody (antibody B). Optionally antibodies A and B may be the same antibody provided there are multiple binding sites on the surface of legionella. Preferably they are different antibodies recognising different epitopes of the legionella. If legionella is present in the water sample, it becomes bound to the latex bead via antibody A. The reporter kinase is bound to the latex bead via the interaction of antibody B with the already-bound legionella. 
The syringe is shaken continuously for 5 minutes either by hand or optionally within a suitable automated shaker. The syringe is applied to a filtration device which contains a filter designed to allow the free passage of the water, non-reporter kinase, ATP, uncomplexed reporter kinase conjugate, and any uncomplexed microorganisms, but which will retain anything bound to the latex bead. Thus, any reporter kinase bound to the latex bead will be retained on the filter.
The filter is removed from the filter housing and transferred into a reagent tube. The presence of legionella is assessed by the addition of ADP, luciferin and luciferase and the measurement of light output using a portable luminometer.
EXAMPLE 15
Detection of Chlamydia in a Swab Sample
A swab device is used to collect a vaginal sample from the test individual. The swab is placed in a reagent tube that contains 1M urea to assist in disrupting the tissue and 2 μM Ap5A final concentration which blocks the activity of any non-reporter kinase. The presence of Ap5A does not have a detrimental effect on the activity of the luciferase (see FIG. 4B), hence even if it is present in the final reaction mixture it does not adversely affect the limits of detection.
A reporter kinase conjugate is prepared by conjugating the adenylate kinase from S. solfataricus to a Chlamydia antigen. A suitable Chlamydia antigen is the major outer membrane protein (MoMP) which is present in high copies on the surface of Chlamydia. A sores of polymorphic membrane proteins have also been described and may represent suitable target antigens for specific and sensitive detection. Antibodies can be generated to this protein, or peptides derived from it according to conventional protocols.
A lateral flow device is prepared as set out in FIG. 5. The sample-receiving zone of the device is coated with an antibody to a Chlamydia antigen. The reporter kinase conjugate is then applied onto the sample-receiving zone of the device, and becomes attached thereto via the interaction between the antigen of the conjugate and the coated antibody.
A small volume of the sample is then spotted onto the sample-receiving zone of the device. Any chlamydia antigen present in the sample displaces the reporter kinase conjugate from the sample-receiving zone and allows flow of the reporter kinase conjugate to the detection zone where it can be measured. The device is then placed in a reagent tube, and with ADP and luciferin/luciferase reagents. The light output signal is measured within 5 minutes.
As an alternative antigen, antibodies raised to the bacterial lipopolysaccharide from Chlamydia may be employed and conjugated to the reporter kinase. This multivalent target may provide greater sensitivity and specificity than other targets. Optionally more than one of the target antigens may be combined to amplify the signal detected.
EXAMPLE 16
Detection of Listeria in a Food Sample
A food sample suspected of containing Listeria is immobilized onto a microtitre plate by non-specifically binding sample components to the plate, treating the plate to prevent further non-specific binding thereto and washing.
A reporter kinase conjugate is prepared by conjugating an antibody specific to Listeria to the pyruvate kinase from S. solfataricus. 
The reporter kinase conjugate is applied to the plate and allowed to bind, prior to further washing/recovery. The plate is now heated to about 90 C for about 1 minute in a cell extraction buffer (in a thermal cycler) to denature any non-reporter AK present and release any ATP that may be trapped within the micro-organism. The plate is then coded to 37° C. and a thermolabile ATPase such as apyrase added. The plate is incubated for about 5 minutes to remove the background ATP, then the temperatures is raised to about 90° C. to denature the thermolabile ATPase.
Next, ADP and a mixture of luciferin and luciferase mixture are added simultaneously to the plate. The kinase acts on the ADP to generate ATP, which subsequently reacts with the luciferin/luciferase to produce light. The light output is measured using a hand-held luminometer and is directly proportional to the concentration of the microorganism present.
EXAMPLE 17
Detection of Salmonella in a Food Sample
A solid phase is prepared by coating magnetic beads with a first anti-salmonella polyclonal antibody raised in Guinea pig.
A reporter kinase conjugate is prepared by conjugating the adenylate kinase from T. maritima to a second anti-salmonella polyclonal antibody raised in Guinea pig.
The food sample to be tested is dispersed in a buffer containing 1M urea plus 2 μM Ap5A and mixed for 5 minutes, in the presence of the magnetic beads and the reporter kinase conjugate. This mixing can be carried out at either room temperature or an elevated temperature. If Salmonella is present in the food sample, it will bind to the first anti-salmonella antibody on the magnetic bead. In turn, the reporter kinase conjugate will bind to the magnetic bead via the interaction between the second anti-salmonella antibody and the already-bound salmonella. 
The magnetic beads are then collected by attraction to a strong magnet and washed with a neutral buffer. The magnet with beads attached is transferred to a reagent tube and ADP, luciferin and luciferase are added simultaneously. The light output signal is read in a luminometer, preferably hand-held, within 5 minutes.
EXAMPLE 18
Validation of Processes for Sterilising Bulk Liquids
Preparation of Indicator 1
A first indicator is prepared by covalently attaching 0.1 mg of pyruvate kinase from Sulfolobus solfataricus to a polystyrene strip.
Preparation of Indicator 2
A second indicator is prepared by attaching 0.1 mg of the adenylate kinase from A. fulgidus to the inner face of a semi-permeable membrane such as a dialysis tube. The A. fulgidus kinase contains a naturally occurring reactive cysteine residue (i.e. not disulfide-bonded within the native enzyme), which can be reacted with BMPH (Pierce). This generates a group capable of reacting with oxidised carbohydrates, as generated, for example, by the treatment of Visking tubing with a suitable oxidising agent. The enzyme is reacted with the oxidised membrane surface to generate a covalently linked indicator.
Validation
The indicator is then attached within the bulk liquid and the sterilisation process (such as autoclaving, the passage of oxidative gases or other chemical sterilisation) is carried out.
The indicator is removed from the bulk liquid on completion of the process, and the residual activity of the kinase is measured. To achieve the measurement the indicators are first incubated in the presence of apyrase, at a concentration of 10 μg/ml for 2 minutes. The apyrase can be inactivated by addition of Ap5A at a concentration of 5 μM. The two indicators can then be read independently by addition of a combined reagent containing ADP, luciferin and luciferase. The measurement is made within 5 minutes using a hand held luminometer, such as a hygiene monitor.
In this example any non-reporter kinase that might be present is destroyed by the treatment conditions and as such specific kinase-reduction steps are not required. The residual activity is then compared to a defined threshold value.
EXAMPLE 19
Validation of the Performance of Cloth Washing Cycles Using Biological Detergents
Preparation of Indicator 1
A first indicator is prepared by cross-linking adenylate kinase from S. solfataricus onto a flexible polystyrene wand using a method based on disulfide bond formation. In this method, the adenylate kinase is derivatised with a heterobifunctional agent such as Sulfosuccinimidyl 6-(3′[2-pyridyldithio]-propionamido)hexanoate (SPDP; Pierce chemical company, UK) at a ratio of between 1-3 SPDP:protein. The derivatised kinase is then reduced by reaction with a reducing agent such as dithiothreitol (DTT), or 2-mercaptoethanesulfonic acid (MESNA), the reducing agent removed by dialysis, and the kinase reacted with a maleimide-derivatised polystyrene surface. Typically, 0.1 mg of kinase is, present on the indicator.
Preparation of Indicator 2
A second indicator is prepared by the non-specific adherence of an adenylate kinase from S. acidocaldarius onto a high-protein binding polystyrene strip. The kinase is prepared at a concentration of 0.5-2 mg/ml in a bicarbonate buffer (pH 9.6), optionally containing the stabilising agent sorbitol at between 0.1 and 2% w/v. The kinase in binding buffer is then incubated with the high protein-binding polystyrene strip for a period of 1-2 hours at 22° C. (or 4° C. overnight). The residual kinase is removed by washing in a phosphate buffered saline. Typically, 0.1 mg of kinase is present on the indicator.
Validation of Wash Cycles
The washer is loaded with the items to be washed, and the indicator is fixed within a suitable holder on the inside of a washer (to facilitate its recover). The wash cycle is then performed. At completion of the cycle, the indicator is removed and the residual activity of the kinase is assessed. In this example the washing process removes and/or inactivates both any non-reporter kinase and any residual ATP, hence neither interfere with the assay. The presence of the reporter kinase is determined by the addition of ADP, followed within 1 minute by the addition of luciferin and luciferase.
If the measurement of residual kinase activity is equal to or below a predetermined threshold level, then the load is cleared for further processing.
EXAMPLE 20
Preparation of a Fibrin-Based Indicator Device
Preparation of tAK Fusions for Cross-Linking to Fibrin
A transglutaminase substrate sequence (MNQEQVSPLGG—SEQ ID No: 33) is added on to the N-terminus, the C-terminus, or both N- and C-termini, of the adenylate kinase from S. acidocaldarius encoded by a codon optimised gene done. This construct is transferred as an NdeI—SalI fragment into an in-house expression vector (pMTL 1015; as described in WO 2005/123764). The expression construct is confirmed by DNA sequencing and transferred into expressions hosts BL21 or RV308 for subsequent expression.
Similarly, the resynthesised tAK gene from Thermatoga maritima (SEQ ID 29) is fused to the transglutaminase sequence in the three orientations identified above. The cloning and preparation of the expression system is also as described above.
The fusion constructs can also be expressed in other expression vector-host combinations with the addition of affinity tags for subsequent purification. Particularly useful in this context are expression vectors which add 6-histidine tags on either the N- or C-terminus of the fusion proteins, modifications which aid purification and detection but do not interfere with the intrinsic properties of the fusion proteins. Vectors for this type of modification include pET series vectors (Novagen/Merck) and pQE series vectors (Qiagen).
To generate material for the indicator devices the expression strains are grown initially in 8-liter fermenters essentially under static culture conditions. In brief, the strains are prepared as seed stocks and subsequently diluted into the 8-liters of growth media (modified terrific broth containing additional glucose). The cultures are grown under standard fermentation conditions until the cultures reached an optical density (OD at 600 nm) demonstrating that they are entering stationary conditions (typically at around an OD=5). The fermenters are then held under minimally aerated conditions for up to 12 hours prior to harvesting of material by continual centrifugation.
Purification of tAK Fusions
The harvested material is then purified according to the following protocol.

    Buffer A: 20 mM Tris-HCl; 900 mM NaCl, pH 7.5
    Wash Buffer: 20 mM Tris-HCl; 200 mM NaCl, pH 7.5
    Buffer B: 20 mM Tris-HCl; 200 mM NaCl, pH 7.5
     10 mM ATP; 10 mM AMP; 10 mM MgCl2 
    MgAc buffer: 15 mM MgAc (1M Fluka BioChemika), pH 6.8
    1. Weigh frozen cell paste (10 g) and resuspend in 3× (30 ml) volume of Buffer A, pH 7.5.
    2. Sonicate on ice ( ̃12,000 khz) using 25 cycles of 30 seconds on/30 seconds off. Take 1 ml sample.
    3. Sonicated cell solution is centrifuged at 6,000 rpm for 30 mins at 4 degrees C. Supernatant carefully poured off and 1 ml sample taken.
    4. Supernatant is heat treated at 80 degrees C. in a water bath for 20 mins. 1 ml sample taken. (This step is an optional step depending on thermal stability of the fusion proteins).
    5. Heat treated solution centrifuged at 6000 rpm for 30 mins. at 4 degrees C. Pour off supernatant and take 1 ml sample.
    6. Filter the sample with 0.2 μm low binding filter before loading onto column.
    7. Equilibrate Blue Sepharose Fast Row column with 5 Column Volumes (CVs) of Buffer A.
    8. Load the Wash column with wash buffer at 0.2 ml/min overnight.
    9. Elute protein with 100% buffer B at a flow rate of 1 ml/min collect product in 2.5 ml fractions.
    10. Once all proteins have eluted wash column with 100% buffer B at 5 ml/min for 5 CV's.
    11. Re-equilibrate column with 5 CV's buffer A.
    12. Rinse column with 5 CVs 20% Ethanol for storage at 4° C.


Optionally, additional protein purification methods are applied to yield a higher purity product. Ion exchange chromatography on either SP-Sepharose Fast Row or Q-Sepharose Fast Flow resins is particularly effective.
The samples are then analysed using a standard assay format to identify fractions containing peak adenylate kinase activity. This is confirmed by SDS-PAGE analysis using standard techniques. In brief, the assay method is carried out using the following protocol:

    1. Dilute the purified tAK fusion 1:1000 and 1:10,000 in Mg Ac Buffer. Add 100 μl per well.
    2. Treat with Apyrase (50 μl/well at 2.5 units per ml stock concentration; Sigma Grade VI Apyrase from potato) and incubate for 30 mins at 30° C., with shaking, to remove ATP.
    3. Incubate plate at 70° C. for 10 mins to denature Apyrase.
    4. Add 50 μl/well of ADP (275 μM ADP in MgAc buffer) and seal. Incubate at 70° C. for 20 mins.
    5. Remove plate and allow to cool to room temperature for 20 mins, warm Luciferase/Luciferin (L/L) reagent to room temperature for 20 mins.
    6. Add 200 μl ATP standard to 1 or 2 empty wells per plate.
    7. Set up injectors on luminometer and prime them with L/L reagent (ATP reagent, Biotherma). Inject 30 μl L/L reagent/well.
    8. Read light generated immediately using luminometer.


The fractions with peak kinase activity are then dialysed extensively against phosphate buffered saline (PBS pH 7.4) and stored until required. Optionally a fusion can be prepared between tAK and the full length fibrinogen molecule to provide further means to incorporate the enzymatic activity within the fibrin film.
Deposition of tAK Fusions onto a Solid Support
The tAK-fibrin fusion is diluted to around 200 μg/ml in either PBS or bicarbonate buffer (pH 9.6) and applied to a solid support of 316 L grade stainless steel, plastic, glass or textiles. The protein is allowed to adhere to the surface for up to 2 hours at room temperature or overnight at 4° C.
Optionally, additional carrier molecules are added at this stage, e.g. sucrose at concentrations up to 1% w/v, albumin at up 1 mg/ml, pig mucin at up to 0.5% w/v. The addition of such carriers may be particularly important for certain types of indicator but the presence of the carrier should not interfere with subsequent interaction and cross-linking to the fibrin film applied in the next stage.
Overlay of Fibrin Containing Soil and Cross-Linking to Fibrin-tAK Fusion
A solution containing fibrinogen is added to effect the cross-linking of the indicator to the fibrin-containing test soil (biological matrix).
A solution containing up to 3 mg/ml fibrinogen (containing Factor XIII), 2.5 mM CaCl2, and thrombin (up to 5 NIH units per ml) is mixed freshly and added to the coated surface of the solid support. The reaction is allowed to proceed at room temperature for up to 30 minutes, depending on the level of cross-linking required. Optionally, albumin (up to 80 mg/ml) and haemoglobin (up to 80 mg/ml) are added at this stage to provide a tougher and more realistic challenge for cleaning of a blood-like soil. After cross-linking, residual liquid is removed and the indicator device left to dry.
Optionally, the tAK-fibrin peptide fusion is added to the fibrin-containing test soil solution (biological matrix) prior its addition to the solid support surface. Cross-linking of the fibrin peptide to the matrix can be increased by adding more Factor XIII and/or extending the duration of the reaction. Cross-linking can also be enhanced by the use of the tAK fusion protein with fibrin peptides added to both ends of the molecule. Optionally a fibrinogen-tAK fusion could be added directly to this solution to provide further cross linkage of the indicator.
Covalent Chemical Cross-Linking of tAK to Fibrin or Fibrinogen.
tAK may be chemically joined to fibrin, fibrin peptides or fibrinogen by a wide range of methods familiar to those working in the field. For example purified protein preparations for fibrinogen or fibrin are obtained from commercial sources (e.g. Sigma). The tAK from S. acidocaldarius is prepared as described above. The tAK is derivatised using the amide reactive reagent SPDP (SPDP (N-Succinimidyl 3-(2-pyridyldithio)-propionate; Pierce chemical company) according to the manufacturer's instructions. The fibrin or fibrinogen is also derivatised using the same protocol. The derivatised tAK is reduced by reaction with mercaptoethanol to yield a reactive sulfhydryl group. This is then mixed with the SPDP-derivatised fibrin causing the formation of covalent bonds between the two molecules. The concentrations of the reaction partners should be determined empirically following the guidelines within the manufacturer's instructions for SPDP. The chemically linked tAK fibrin or fibrinogen can be used interchangeably or in addition to the fusion protein.
Uses of Fibrin-tAK Indicators
Use in a Washer Disinfector
An indicator is prepared as described above. Preferably the solid support is a rectangular stainless steel strip 55 mm×5 mm×0.75 mm, which may be coated on one or both surfaces. One or preferably several indicator strips are positioned within the chamber of the washer disinfector. Optimally these may be positioned in sites which may be the most difficult to dean, providing the highest degree of certainty that the wash process has been effective. Alternatively they may be positioned to monitor the function of multiple spray arms (i.e. where these may be independent of each other). The indicator strips are clipped to the shelves or other substructure of the washer-disinfector chamber to ensure that they do not move during the wash treatment. The orientation of the surrogate devices can be modified to provide further information about the efficacy of the wash process, for example by positioning them so that the coated surface are at right angles to the direction of water spray.
The instrument load is added and the standard run cycle performed. At the end of the run the devices are removed from the chamber and the presence of residual tAK-fusion assessed, as outlined below, prior to the removal of the instruments and any subsequent processing. Optionally devices can be removed during the wash process either by interrupting the process at carefully defined points or by using a machine that provides a method of withdrawing the indicator during the run.
Use in Endoscope Test Procedure
The indicator device for monitoring an endoscope reprocessing system is essentially similar to that outlined above. A similar size indicator surface, representative of either the stainless steel components within an endoscope, the PTFE tubing or other relevant materials is placed within a tubular chamber. This is attached, via suitable screw, push or bayonet fittings to either the front end of the endoscope or, more preferably the end which makes contact with patient tissues. This is placed within the endoscope reprocessing unit and the ends of the endoscope tubing and indicator device are coupled to the ports in the unit. The process is run as standard and the indicator device removed at the end of the run for analysis, prior to onward processing or the return of the endoscope to use.
Means of Assessing Cleaning Performance
The indicator device is removed at the end of the test process. The indicator strip is then placed into a reagent tube with ADP, luciferin and luciferase, added simultaneously, with signal being read-out on a hand-held luminometer with 2 minutes.
EXAMPLE 21
Preparation of tAK-Sup35 Fusion
Clones containing the N-terminal domain of Sup35 from Saccharomyces cerevisiae fused to either the N- or C-terminus, or both termini, of adenylate kinases from either S. acidocaldarius or T. maritima are generated by standard DNA manipulation techniques. All clones are transferred as NdeI—SalI fragments into the pMTL1015 expression vector and their sequences verified. The expression constructs are used to transform BL21 or RV308 expression strains and the material grown in large scale fermentation conditions, but with minimal aeration.
Expression and purification of a tAK-Sup35 fusion is essentially the same as for the fibrin-peptide fusions described in Example 20, except that the use of the thermal denaturation step (Step 4) is not part of the purification protocol. In brief, cell paste from the fermenter is resuspended in buffer A, and lysed by sonication. The cell debris is removed (no heat treatment is typically used for these type of fusions) and the supernatant used for column purification as outlined in Example 20.
Under certain growth conditions the fusion proteins may be insoluble, being apparent as inclusion bodies within the cells. In this case the cell pellets are prepared and lysed in the same way, but the resulting insoluble fraction, containing the inclusion bodies, is collected by centrifugation. This material is washed in a buffer (e.g. PBS) containing Triton X100 (up to concentrations of 5%). After each wash the pellet containing the fusion proteins is separated by centrifugation. After 5 washes the inclusion bodies are resolubilised in PBS containing 8M urea and agitated gently for up to 30 minutes. Any residual insoluble material is removed by centrifugation. The urea-solubilised material is dialysed against up to 5×10 volumes of PBS to remove the urea and allow the fusion proteins to refold. Optionally the urea may be removed more rapidly by spraying the urea-solubilised preparation through a fine gauge needle into 100 volumes of rapidly stirred PBS or buffer A as used for purification. The material is allowed to stand at room temperature with stirring for up to 30 minutes prior to subsequent processing.
Subsequent purification of the fusions is carried out essentially as described in Example 20. The supernatant from either lysed cells or solubilised and refolded inclusion bodies is loaded onto a pre-equilibrated Blue Sepharose Fast Flow column. After extensive washing in buffer A and subsequently in wash buffer, the protein is eluted using buffer B. Peak fractions are determined by SDS-PAGE analysis and enzyme assay. Fractions are then pooled and dialysed into PBS.
Conversion of tAK-Sup35 to an Amyloid Form
The Sup35-tAK fusions when assembled into fibrils are more representative of amyloid proteins such as prions which are key molecules against which to assess the efficacy of decontamination processes.
The amyloid form of the Sup35-tAK fusions is generated by either refolding of the purified soluble protein or by modifying the conditions used for dialysis of the urea-resolubilised inclusion body preparations, in the first case, a conformational change is induced by exposure of the fusion proteins to conditions around pH4 (e.g by dialysis into a suitably buffered solution at pH 7.4 optionally containing up to 1M NaCl). In the latter case, the resolubilised fusion proteins in 8M urea/PBS are dialysed for 6-12 hours at room temperature against 2M urea, 300 mM NaCl, in PBS (pH 7.4). Alternatively, the fibrilisation can be induced by dialysis against 20 mM Tris pH8.0 10 mM EDTA under similar incubation conditions. Optionally, the fusion proteins may be incorporated into fibrils containing normal Sup35. This is achieved by mixing the fusions with unfused Sup35 expressed in the same way, at ratios between 1:1 to 1:10 fusion:Sup35.
Deposition of tAK-Sup35 Fusions onto Solid Support.
Deposition of the fibrils onto a solid support is effected by simple protein adsorption in a suitable buffer (e.g. PBS pH 7.4 Bicarbonate buffer pH 9.6) in the presence of high levels of NaCl. The use of charged or precoated surfaces (e.g. plastics coated with Poly-L-lysine) is useful in providing surfaces which can more effectively bind the fusion proteins. Optionally, the fibrils may be deposited in a suitable carrier, such as sucrose (to 1%), pig mucin (up to 0.5%), or albumin (up to 1 mg/ml).
Overlay of Test Soil
A test soil (biological matrix) is then overlaid onto the amyloid preparation adhered onto the surface as described above.
Suitable biological matrices in which the amyloid indicator is embedded include e.g. 0.5% mucin, with or without albumin, a commercial test soil (such as that manufactured by Browne's) or any one of the test soils identified in guidance documents issues by national and international standards committees (e.g. Edinburgh soil as detailed in HTM 01/01 (UK).
Assembly of Amyloid Fibrils within the Test Soil
Given the ability of amyloids to self-assemble in complex matrices it is possible for the amyloid-tAK fusion to be mixed with soil components prior to fibril formation and subsequent deposit onto surfaces. This provides further options for indicators in which the amyloid fibrils may be mixed and inter-chelated with other soil components providing a different type of matrix that may be harder to remove from surfaces.
Use of tAK-Sup35 Indicator for Assessing Prion Removal from Surfaces in a Washing Process
An indicator as described above is prepared as fibrils and dried down onto a steel surface in the presence of 0.5% mucin. The indicator is placed within the chamber of a washer disinfector at pre-determined locations. The instrument load is added. The process is started as per the manufacturer's instructions and any process records completed. At the end of the process, and before any instruments are taken from the machine, the indicator devices are removed and assessed as described in Example 20.
Use of tAK-Sup35 Indicator for Assessing Prion Inactivation in a Protease-Based Process
Indicators as described above are prepared as fibrils with a high ratio of free Sup35:Sup35-tAK (n excess of 5:1) and deposited onto solid support strips in the presence of Edinburgh sod. The indicator devices are inserted into a pre-soak bath containing freshly made PrionzymeTM (Genencor International) prion inactivation treatment (at 60° C., pH 12). The indicator strips are cupped to the side of the bath such that the ends of the indicators are within the bulk of the liquid. Instruments are added as required and processed for 30 minutes. The indicator devices are removed from the bath at the end of the process, prior to removal of the instruments and assessed as described in Example 20.
Use of tAK-Sup35 Indicator for an Oxidative Process Aimed at Destroying Prions.
An indicator as described above is prepared as fibrils using only Sup35-tAK, and deposited onto a stainless steel surface (optionally in the presence of 0.1% w/v sucrose). The indicator is attached to the inside of the lid of a GenesisTM container in which the instruments are prepared for processing and the lid closed. The container is inserted into the load chamber of a suitable processor for oxidative challenge (e.g. the 125 L ozone steriliser; TSO3 or a vapour phase hydrogen peroxide technology such as that described in published papers by Fichet et al 2004; Lancet) and the process run according to manufacturers' instructions. At the end of the process, the Genesis container is taken out of the chamber and the indicator devices are removed and processed as described in Example 20.
EXAMPLE 22
Detection of a Reporter Kinase in a Sample Due to an Infection; Use for Rapid Assay of Infection in Patient Sample
A patient presented at the clinic with suspected infection from the obligate intracellular pathogen Burkholderia pseudomallei. A blood sample was removed and dispersed in a buffer containing 1M urea plus 5 μM Ap4A. The sample was assayed by addition of ADP and luciferin/luciferase reagent, incubated for 2 minutes and the light output measured in a hand-held luminometer. The signal generated is directly proportional to the amount of B. pseudomallei within the blood sample.
Detection of a Reporter Kinase in a Sample Due to an Infection; Use for Rapid Assay of Infection in Cell Models
The study of intracellular bacterial pathogens is complicated by the need to grow them in mammalian cell culture systems. Measurement of viable cells the requires subsequent culture or re-infection into mammalian host cells, both of which are very time consuming methods. A rapid assay, such as provided by the invention, is invaluable in providing information that can be used in real-time to determine the results of an experiment.
A suitable isolate of B. pseudomallei was incubated with a permissive cell culture model capable of supporting growth of the bacteria within the cell. The culture was grown for an appropriate length of time to establish the infection.
Cells were isolated by centrifugation and lysed by resuspension in a buffer containing 1% Triton X-100, 5 μM Ap4A. A detection reagent containing ADP, luciferin and luciferase was added and incubated for 5 minutes. The light output was read in a 96-well plate luminometer. The amount of signal generated is proportional to the number of viable B. pseudomallei cells within the cell culture. Optionally this rapid assay method can be extended to measure the effects of vaccines or drugs that reduce the number of viable cells within the cell culture.
For example, antibodies raised in a patient immunised with a prototype B. pseudomallei vaccine are mixed with the organisms prior to addition to the permissive cell culture. After an incubation period sufficient to allow uptake of non-neutralised microorganisms, the cells are washed and incubated for a period of time sufficient to establish the infection. Cells are then washed and lysed as described above, again in the presence of inhibitor. The signal measured by simultaneous addition of ADP, luciferin and luciferase is proportional to the number of non-neutralised microorganisms giving a measure of the effectiveness of the vaccine and/or the immune response generated in a vaccinated individual. Such methods are suitable for high-throughput screening.
In a further example, infected cell cultures are set up as described above. After the infection is established, antibiotics are used to treat the infected culture, with the express aim of killing the bacteria within the host cells. After the antibiotics have been applied, the cultures are incubated for sufficient time for the antibiotic to have its effect. The cells are lysed in the presence of inhibitor as described above and the number of viable cells quantified by measurement of the reporter kinase, by addition of ADP, luciferin and luciferase.
