     FIELD OF THE INVENTION 
     The present invention relates to antigen binding proteins and fragments thereof that specifically bind B cell maturation antigen (BCMA) and in particular human BCMA (hBCMA). 
     The present invention also concerns methods of treating diseases or disorders with said antigen binding fragments, pharmaceutical compositions comprising said antigen binding fragments and methods of manufacture. Other embodiments of the present invention will be apparent from the description below. 
     BACKGROUND OF THE INVENTION 
     BCMA (CD269 or TNFRSF17) is a member of the TNF receptor superfamily. It is a non-glycosylated integral membrane receptor for the ligands BAFF and APRIL. BCMA&#39;s ligands can also bind additional receptors: TACI (Transmembrane Activator and Calcium modulator and cyclophilin ligand Interactor), which binds APRIL and BAFF; as well as BAFF-R (BAFF Receptor or BR3), which shows restricted but high affinity for BAFF. Together, these receptors and their corresponding ligands regulate different aspects of humoral immunity, B-cell development and homeostasis. 
     BCMA&#39;s expression is typically restricted to the B-cell lineage and is reported to increase in terminal B-cell differentiation. BCMA is expressed by human plasma blasts, plasma cells from tonsils, spleen and bone marrow, but also by tonsillar memory B cells and by germinal centre B cells, which have a TACI-BAFFR low phenotype (Darce et al, 2007). BCMA is virtually absent on naïve and memory B-cells (Novak et al., 2004a and b). The BCMA antigen is expressed on the cell surface so is accessible to the antibody, but is also expressed in the golgi. As suggested by its expression profile, BCMA signalling, typically linked with B-cell survival and proliferation, is important in the late stages of B-cell differentiation, as well as the survival of long lived bone marrow plasma cells (O&#39;Connor et al., 2004) and plasmablasts (Avery et al., 2003). Furthermore, as BCMA binds APRIL with high affinity, the BCMA-APRIL signalling axis is suggested to predominate at the later stages of B-cell differentiation, perhaps being the most physiologically relevant interaction. 
     Multiple Myeloma (MM) is a clonal B-cell malignancy that occurs in multiple sites within the bone marrow before spreading to the circulation; either de novo, or as a progression from monoclonal gammopathy of undetermined significance (MGUS). It is commonly characterised by increases in paraprotein and osteoclast activity, as well as hypercalcaemia, cytopenia, renal dysfunction, hyperviscosity and peripheral neuropathy. Decreases in both normal antibody levels and numbers of neutrophils are also common, leading to a life threatening susceptibility to infection. BCMA has been implicated in the growth and survival of myeloma cell lines in vitro (Novak et al., 2004a and b; Moreaux et al., 2004). 
     BCMA expression (both transcript and protein) is reported to correlate with disease progression in MM. Using Affymetrix microarrays, it was demonstrated that the TACI and BCMA genes were over-expressed in Multiple Myeloma Cells (MMC) compared with their normal counterparts (Moreaux et al, 2004). Gene expression analysis has been used to compare human myeloma cells with purified plasma cells from patients with MGUS and from normal bone marrow as well as with primary tumour cells from B-cell lineage leukaemias (Bellucci et al, 2005). The BCMA gene was highly expressed in all myeloma samples. Although purified plasma cells from patients with MGUS had lower expression of BCMA, there was no significant difference when compared with the expression found in normal plasma cells or myeloma cells. In contrast, BCMA expression was significantly lower in B-cell Chronic Lymphocytic Leukaemia (CLL), pre-B Acute Lymphocytic Leukaemia (ALL) and T-cell ALL (T-ALL). 
     Mouse models that transgenically over-express BAFF or APRIL have a significant increase in B-cell lymphomas (Batten et al., 2004—BAFF; Planelles et al., 2004—APRIL). In humans, excess BAFF and APRIL have been detected in the sera and micro-environments of patients with a number of B-cell malignancies, as well as other B-cell disorders.

     In another aspect the antigen binding protein binds to human BCMA with high affinity for example when measured by Biacore the antigen binding protein binds to human BCMA with an affinity of 20 nM or less or an affinity of 15 nM or less or an affinity of 5 nM or less or an affinity of 1000 pM or less or an affinity of 500 pM or less or an affinity of 400 pM or less, or 300 pM or less or for example about 120 pM. In a further embodiment the antigen binding protein binds to human BCMA when measured by Biacore of between about 100 pM and about 500 pM or between about 100 pM and about 400 pM, or between about 100 pM and about 300 pM. In one embodiment of the present invention the antigen binding protein binds BCMA with an affinity of less than 150 pm. 
     In one such embodiment, this is measured by Biacore, for example as set out in Example 4. 
     In another aspect the antigen binding protein binds to human BCMA and neutralises the binding of the ligands BAFF and/or APRIL to the BCMA receptor in a cell neutralisation assay wherein the antigen binding protein has an IC50 of between about 1 nM and about 500 nM, or between about 1 nM and about 100 nM, or between about 1 nM and about 50 nM, or between about 1 nM and about 25 nM, or between about 5 nM and about 15 nM. In a further embodiment of the present invention the antigen binding protein binds BCMA and neutralises BCMA in a cell neutralisation assay wherein the antigen binding protein has an IC50 of about 10 nM. 
     In one such embodiment, this is measured by a cell neutralisation assay, for example as set out in Example 4.6. 
     The antigen binding proteins, for example antibodies of the present invention may be produced by transfection of a host cell with an expression vector comprising the coding sequence for the antigen binding protein of the invention. An expression vector or recombinant plasmid is produced by placing these coding sequences for the antigen binding protein in operative association with conventional regulatory control sequences capable of controlling the replication and expression in, and/or secretion from, a host cell. Regulatory sequences include promoter sequences, e.g., CMV promoter, and signal sequences which can be derived from other known antibodies. Similarly, a second expression vector can be produced having a DNA sequence which encodes a complementary antigen binding protein light or heavy chain. In certain embodiments this second expression vector is identical to the first except insofar as the coding sequences and selectable markers are concerned, so to ensure as far as possible that each polypeptide chain is functionally expressed. Alternatively, the heavy and light chain coding sequences for the antigen binding protein may reside on a single vector. 
     A selected host cell is co-transfected by conventional techniques with both the first and second vectors (or simply transfected by a single vector) to create the transfected host cell of the invention comprising both the recombinant or synthetic light and heavy chains. The transfected cell is then cultured by conventional techniques to produce the engineered antigen binding protein of the invention. The antigen binding protein which includes the association of both the recombinant heavy chain and/or light chain is screened from culture by appropriate assay, such as ELISA or RIA. Similar conventional techniques may be employed to construct other antigen binding proteins. 
     Suitable vectors for the cloning and subcloning steps employed in the methods and construction of the compositions of this invention may be selected by one of skill in the art. For example, the conventional pUC series of cloning vectors may be used. One vector, pUC19, is commercially available from supply houses, such as Amersham (Buckinghamshire, United Kingdom) or Pharmacia (Uppsala, Sweden). Additionally, any vector which is capable of replicating readily, has an abundance of cloning sites and selectable genes (e.g., antibiotic resistance), and is easily manipulated may be used for cloning. Thus, the selection of the cloning vector is not a limiting factor in this invention. The expression vectors may also be characterized by genes suitable for amplifying expression of the heterologous DNA sequences, e.g., the mammalian dihydrofolate reductase gene (DHFR). Other vector sequences include a poly A signal sequence, such as from bovine growth hormone (BGH) and the betaglobin promoter sequence (betaglopro). The expression vectors useful herein may be synthesized by techniques well known to those skilled in this art. 
     The components of such vectors, e.g. replicons, selection genes, enhancers, promoters, signal sequences and the like, may be obtained from commercial or natural sources or synthesized by known procedures for use in directing the expression and/or secretion of the product of the recombinant DNA in a selected host. Other appropriate expression vectors of which numerous types are known in the art for mammalian, bacterial, insect, yeast, and fungal expression may also be selected for this purpose. 
     The present invention also encompasses a cell line transfected with a recombinant plasmid containing the coding sequences of the antigen binding proteins of the present invention. Host cells useful for the cloning and other manipulations of these cloning vectors are also conventional. However, cells from various strains of  E. Coli  may be used for replication of the cloning vectors and other steps in the construction of antigen binding proteins of this invention. 
     Suitable host cells or cell lines for the expression of the antigen binding proteins of the invention include mammalian cells such as NS0, Sp2/0, CHO (e.g. DG44), COS, HEK, a fibroblast cell (e.g., 3T3), and myeloma cells, for example it may be expressed in a CHO or a myeloma cell. Human cells may be used, thus enabling the molecule to be modified with human glycosylation patterns. Alternatively, other eukaryotic cell lines may be employed. The selection of suitable mammalian host cells and methods for transformation, culture, amplification, screening and product production and purification are known in the art. See, e.g., Sambrook et al., cited above. 
     Bacterial cells may prove useful as host cells suitable for the expression of the recombinant Fabs or other embodiments of the present invention (see, e.g., Plückthun, A., Immunol. Rev., 130:151-188 (1992)). However, due to the tendency of proteins expressed in bacterial cells to be in an unfolded or improperly folded form or in a non-glycosylated form, any recombinant Fab produced in a bacterial cell would have to be screened for retention of antigen binding ability. If the molecule expressed by the bacterial cell was produced in a properly folded form, that bacterial cell would be a desirable host, or in alternative embodiments the molecule may express in the bacterial host and then be subsequently re-folded. For example, various strains of  E. coli  used for expression are well-known as host cells in the field of biotechnology. Various strains of  B. subtilis, Streptomyces , other bacilli and the like may also be employed in this method. 
     Where desired, strains of yeast cells known to those skilled in the art are also available as host cells, as well as insect cells, e.g.  Drosophila  and  Lepidoptera  and viral expression systems. See, e.g. Miller et al., Genetic Engineering, 8:277-298, Plenum Press (1986) and references cited therein. 
     The general methods by which the vectors may be constructed, the transfection methods required to produce the host cells of the invention, and culture methods necessary to produce the antigen binding protein of the invention from such host cell may all be conventional techniques. Typically, the culture method of the present invention is a serum-free culture method, usually by culturing cells serum-free in suspension. Likewise, once produced, the antigen binding proteins of the invention may be purified from the cell culture contents according to standard procedures of the art, including ammonium 21eroxidi precipitation, affinity columns, column chromatography, gel electrophoresis and the like. Such techniques are within the skill of the art and do not limit this invention. For example, preparations of altered antibodies are described in WO 99/58679 and WO 96/16990. 
     Yet another method of expression of the antigen binding proteins may utilize expression in a transgenic animal, such as described in U.S. Pat. No. 4,873,316. This relates to an expression system using the animals casein promoter which when transgenically incorporated into a mammal permits the female to produce the desired recombinant protein in its milk. In a further embodiment of the invention there is provided a method of producing an antibody of the invention which method comprises the step of culturing a host cell transformed or transfected with a vector encoding the light and/or heavy chain of the antibody of the invention and recovering the antibody thereby produced. 
     In accordance with the present invention there is provided a method of producing an anti-BCMA antibody of the present invention which binds to and neutralises the activity of human BCMA which method comprises the steps of; 
     providing a first vector encoding a heavy chain of the antibody; 
     providing a second vector encoding a light chain of the antibody; 
     transforming a mammalian host cell (e.g. CHO) with said first and second vectors; culturing the host cell of step (c) under conditions conducive to the secretion of the antibody from said host cell into said culture media; 
     recovering the secreted antibody of step (d). 
     Once expressed by the desired method, the antibody is then examined for in vitro activity by use of an appropriate assay. Presently conventional ELISA assay formats are employed to assess qualitative and quantitative binding of the antibody to BCMA. Additionally, other in vitro assays may also be used to verify neutralizing efficacy prior to subsequent human clinical studies performed to evaluate the persistence of the antibody in the body despite the usual clearance mechanisms. 
     The dose and duration of treatment relates to the relative duration of the molecules of the present invention in the human circulation, and can be adjusted by one of skill in the art depending upon the condition being treated and the general health of the patient. It is envisaged that repeated dosing (e.g. once a week or once every two weeks or once every 3 weeks) over an extended time period (e.g. four to six months) may be required to achieve maximal therapeutic efficacy. 
     In one embodiment of the present invention there is provided a recombinant transformed, transfected or transduced host cell comprising at least one expression cassette, for example where the expression cassette comprises a polynucleotide encoding a heavy chain of an antigen binding protein according to the invention described herein and further comprises a polynucleotide encoding a light chain of an antigen binding protein according to the invention described herein or where there are two expression cassettes and the 1 st  encodes the light chain and the second encodes the heavy chain. For example in one embodiment the first expression cassette comprises a polynucleotide encoding a heavy chain of an antigen binding protein comprising a constant region or antigen binding fragment thereof which is linked to a constant region according to the invention described herein and further comprises a second cassette comprising a polynucleotide encoding a light chain of an antigen binding protein comprising a constant region or antigen binding fragment thereof which is linked to a constant region according to the invention described herein for example the first expression cassette comprises a polynucleotide encoding a heavy chain selected from SEQ. ID. NO:56, or SEQ. ID. NO: 60 or SEQ. ID. NO: 62 and a second expression cassette comprising a polynucleotide encoding a light chain selected from SEQ. ID. NO: 64 or SEQ. ID. NO: 66.

ID. NO: 55, or SEQ. ID. NO: 59 or SEQ. ID. NO: 61 and a second vector encoding a light chain for example the light chain of SEQ ID NO: 63 or SEQ. ID. NO: 65. In one such example the first vector encodes a heavy chain selected from SEQ. ID. NO: 55 and a second vector encoding a light chain for example the light chain of SEQ ID NO: 63.

In one embodiment the suspension or solution is buffered at physiological pH. In one embodiment the compositions for parenteral administration will comprise a solution of the antigen binding protein of the invention or a cocktail thereof dissolved in a pharmaceutically acceptable carrier. In one embodiment the carrier is an aqueous carrier. A variety of aqueous carriers may be employed, e.g., 0.9% saline, 0.3% glycine, and the like. These solutions may be made sterile and generally free of particulate matter. These solutions may be sterilized by conventional, well known sterilization techniques (e.g., filtration). The compositions may contain pharmaceutically acceptable auxiliary substances as required to approximate physiological conditions such as pH adjusting and buffering agents, etc. The concentration of the antigen binding protein of the invention in such pharmaceutical formulation can vary widely, i.e., from less than about 0.5%, usually at or at least about 1% to as much as about 15 or 20% by weight and will be selected primarily based on fluid volumes, viscosities, etc., according to the particular mode of administration selected.

     Definitions 
     As used herein, the terms “cancer,” “neoplasm,” and “tumor” are used interchangeably and, in either the singular or plural form, refer to cells that have undergone a malignant transformation that makes them pathological to the host organism. Primary cancer cells can be readily distinguished from non-cancerous cells by well-established techniques, particularly histological examination. The definition of a cancer cell, as used herein, includes not only a primary cancer cell, but any cell derived from a cancer cell ancestor. This includes metastasized cancer cells, and in vitro cultures and cell lines derived from cancer cells. When referring to a type of cancer that normally manifests as a solid tumor, a “clinically detectable” tumor is one that is detectable on the basis of tumor mass; e.g., by procedures such as computed tomography (CT) scan, magnetic resonance imaging (MRI), X-ray, ultrasound or palpation on physical examination, and/or which is detectable because of the expression of one or more cancer-specific antigens in a sample obtainable from a patient. Tumors may be a hematopoietic (or hematologic or hematological or blood-related) cancer, for example, cancers derived from blood cells or immune cells, which may be referred to as “liquid tumors.” Specific examples of clinical conditions based on hematologic tumors include leukemias such as chronic myelocytic leukemia, acute myelocytic leukemia, chronic lymphocytic leukemia and acute lymphocytic leukemia; plasma cell malignancies such as multiple myeloma, MGUS and Waldenström&#39;s macroglobulinemia; lymphomas such as non-Hodgkin&#39;s lymphoma, Hodgkin&#39;s lymphoma; and the like. 
     The cancer may be any cancer in which an abnormal number of blast cells or unwanted cell proliferation is present or that is diagnosed as a hematological cancer, including both lymphoid and myeloid malignancies. Myeloid malignancies include, but are not limited to, acute myeloid (or myelocytic or myelogenous or myeloblastic) leukemia (undifferentiated or differentiated), acute promyeloid (or promyelocytic or promyelogenous or promyeloblastic) leukemia, acute myelomonocytic (or myelomonoblastic) leukemia, acute monocytic (or monoblastic) leukemia, erythroleukemia and megakaryocytic (or megakaryoblastic) leukemia. These leukemias may be referred together as acute myeloid (or myelocytic or myelogenous) leukemia (AML). Myeloid malignancies also include myeloproliferative disorders (MPD) which include, but are not limited to, chronic myelogenous (or myeloid) leukemia (CML), chronic myelomonocytic leukemia (CMML), essential thrombocythemia (or thrombocytosis), and polcythemia vera (PCV). Myeloid malignancies also include myelodysplasia (or myelodysplastic syndrome or MDS), which may be referred to as refractory anemia (RA), refractory anemia with excess blasts (RAEB), and refractory anemia with excess blasts in transformation (RAEBT); as well as myelofibrosis (MFS) with or without agnogenic myeloid metaplasia. 
     Hematopoietic cancers also include lymphoid malignancies, which may affect the lymph nodes, spleens, bone marrow, peripheral blood, and/or extranodal sites. Lymphoid cancers include B-cell malignancies, which include, but are not limited to, B-cell non-Hodgkin&#39;s lymphomas (B-NHLs). B-NHLs may be indolent (or low-grade), intermediate-grade (or aggressive) or high-grade (very aggressive). Indolent Bcell lymphomas include follicular lymphoma (FL); small lymphocytic lymphoma (SLL); marginal zone lymphoma (MZL) including nodal MZL, extranodal MZL, splenic MZL and splenic MZL with villous lymphocytes; lymphoplasmacytic lymphoma (LPL); and mucosa-associated-lymphoid tissue (MALT or extranodal marginal zone) lymphoma. Intermediate-grade B-NHLs include mantle cell lymphoma (MCL) with or without leukemic involvement, diffuse large cell lymphoma (DLBCL), follicular large cell (or grade 3 or grade 3B) lymphoma, and primary mediastinal lymphoma (PML). High-grade B-NHLs include Burkitt&#39;s lymphoma (BL), Burkitt-like lymphoma, small non-cleaved cell lymphoma (SNCCL) and lymphoblastic lymphoma. Other B-NHLs include immunoblastic lymphoma (or immunocytoma), primary effusion lymphoma, HIV associated (or AIDS related) lymphomas, and post-transplant lymphoproliferative disorder (PTLD) or lymphoma. B-cell malignancies also include, but are not limited to, chronic lymphocytic leukemia (CLL), prolymphocytic leukemia (PLL), Waldenström&#39;s macroglobulinemia (WM), hairy cell leukemia (HCL), large granular lymphocyte (LGL) leukemia, acute lymphoid (or lymphocytic or lymphoblastic) leukemia, and Castleman&#39;s disease. NHL may also include T-cell non-Hodgkin&#39;s lymphoma s(T-NHLs), which include, but are not limited to T-cell non-Hodgkin&#39;s lymphoma not otherwise specified (NOS), peripheral T-cell lymphoma (PTCL), anaplastic large cell lymphoma (ALCL), angioimmunoblastic lymphoid disorder (AILD), nasal natural killer (NK) cell/T-cell lymphoma, gamma/delta lymphoma, cutaneous T cell lymphoma, mycosis fungoides, and Sezary syndrome. 
     Hematopoietic cancers also include Hodgkin&#39;s lymphoma (or disease) including classical Hodgkin&#39;s lymphoma, nodular sclerosing Hodgkin&#39;s lymphoma, mixed cellularity Hodgkin&#39;s lymphoma, lymphocyte predominant (LP) Hodgkin&#39;s lymphoma, nodular LP Hodgkin&#39;s lymphoma, and lymphocyte depleted Hodgkin&#39;s lymphoma. Hematopoietic cancers also include plasma cell diseases or cancers such as multiple myeloma (MM) including smoldering MM, monoclonal gammopathy of undetermined (or unknown or unclear) significance (MGUS), plasmacytoma (bone, extramedullary), lymphoplasmacytic lymphoma (LPL), Waldenström&#39;s Macroglobulinemia, plasma cell leukemia, and primary amyloidosis (AL). Hematopoietic cancers may also include other cancers of additional hematopoietic cells, including polymorphonuclear leukocytes (or neutrophils), basophils, eosinophils, dendritic cells, platelets, erythrocytes and natural killer cells. Tissues which include hematopoietic cells referred herein to as “hematopoietic cell tissues” include bone marrow; peripheral blood; thymus; and peripheral lymphoid tissues, such as spleen, lymph nodes, lymphoid tissues associated with mucosa (such as the gut-associated lymphoid tissues), tonsils, Peyer&#39;s patches and appendix, and lymphoid tissues associated with other mucosa, for example, the bronchial linings. 
     The term “antigen binding protein” as used herein refers to antibodies, antibody fragments and other protein constructs which are capable of binding to and neutralising human BCMA. 
     The terms Fv, Fc, Fd, Fab, or F(ab)2 are used with their standard meanings (see, e.g., Harlow et al., Antibodies A Laboratory Manual, Cold Spring Harbor Laboratory, (1988)). 
     The term “antibody” is used herein in the broadest sense and specifically covers monoclonal antibodies (including full length monoclonal antibodies), polyclonal antibodies, multispecific antibodies (e.g. bispecific antibodies) 
     The term “monoclonal antibody” as used herein refers to an antibody obtained from a population of substantially homogenous antibodies i.e. the individual antibodies comprising the population are identical except for possible naturally occurring mutations that may be present in minor amounts. Monoclonal antibodies are highly specific being directed against a single antigenic binding site. Furthermore, in contrast to polyclonal antibody preparations which typically include different antibodies directed against different determinants (epitopes), each monoclonal antibody is directed against a single determinant on the antigen. 
     A “chimeric antibody” refers to a type of engineered antibody in which a portion of the heavy and/or light chain is identical with or homologous to corresponding sequences in antibodies derived from a particular donor antibody class or subclass, while the remainder of the chain(s) is identical with or homologous to corresponding sequences in antibodies derived from another species or belonging to another antibody class or subclass, as well as fragments of such antibodies, so long as they exhibit the desired biological activity (U.S. Pat. No. 4,816,567 and Morrison et al.  Proc. Natl. Acad. Sci. USA  81:6851-6855) (1984)). 
     A “humanised antibody” refers to a type of engineered antibody having its CDRs derived from a non-human donor immunoglobulin, the remaining immunoglobulin-derived parts of the molecule being derived from one (or more) human immunoglobulin(s). In addition, framework support residues may be altered to preserve binding affinity (see, e.g., Queen et al., Proc. Natl Acad Sci USA, 86:10029-10032 (1989), Hodgson et al., Bio/Technology, 9:421 (1991)). A suitable human acceptor antibody may be one selected from a conventional database, e.g., the KABAT® database, Los Alamos database, and Swiss Protein database, by homology to the nucleotide and amino acid sequences of the donor antibody. A human antibody characterized by a homology to the framework regions of the donor antibody (on an amino acid basis) may be suitable to provide a heavy chain constant region and/or a heavy chain variable framework region for insertion of the donor CDRs. A suitable acceptor antibody capable of donating light chain constant or variable framework regions may be selected in a similar manner. It should be noted that the acceptor antibody heavy and light chains are not required to originate from the same acceptor antibody. The prior art describes several ways of producing such humanised antibodies—see for example EP-A-0239400 and EP-A-054951. 
     For nucleic acids, the term “substantial identity” indicates that two nucleic acids, or designated sequences thereof, when optimally aligned and compared, are identical, with appropriate nucleotide insertions or deletions, in at least about 80% of the nucleotides, at least about 90% to about 95%, or at least about 98% to about 99.5% of the nucleotides. Alternatively, substantial identity exists when the segments will hybridize under selective hybridization conditions, to the complement of the strand. 
     “Identity,” means, for polynucleotides and polypeptides, as the case may be, the comparison calculated using an algorithm provided in (1) and (2) below:
         (1) Identity for polynucleotides is calculated by multiplying the total number of nucleotides in a given sequence by the integer defining the percent identity divided by 100 and then subtracting that product from said total number of nucleotides in said sequence, or: nn≤xn−(xn·y), wherein nn is the number of nucleotide alterations, xn is the total number of nucleotides in a given sequence, y is 0.95 for 95%, 0.97 for 97% or 1.00 for 100%, and · is the symbol for the multiplication operator, and wherein any non-integer product of xn and y is rounded down to the nearest integer prior to subtracting it from xn. Alterations of a polynucleotide sequence encoding a polypeptide may create nonsense, missense or frameshift mutations in this coding sequence and thereby alter the polypeptide encoded by the polynucleotide following such alterations.   (2) Identity for polypeptides is calculated by multiplying the total number of amino acids by the integer defining the percent identity divided by 100 and then subtracting that product from said total number of amino acids, or:       

         na≤xa −( xa·y ),
 
     wherein na is the number of amino acid alterations, xa is the total number of amino acids in the sequence, y is 0.95 for 95%, 0.97 for 97% or 1.00 for 100%, and · is the symbol for the multiplication operator, and wherein any non-integer product of xa and y is rounded down to the nearest integer prior to subtracting it from xa 
     For nucleotide and amino acid sequences, the term “identical” indicates the degree of identity between two nucleic acid or amino acid sequences when optimally aligned and compared with appropriate insertions or deletions. 
     “Isolated” means altered “by the hand of man” from its natural state, has been changed or removed from its original environment, or both. For example, a polynucleotide or a polypeptide naturally present in a living organism is not “isolated,” but the same polynucleotide or polypeptide separated from the coexisting materials of its natural state is “isolated”, including but not limited to when such polynucleotide or polypeptide is introduced back into a cell, even if the cell is of the same species or type as that from which the polynucleotide or polypeptide was separated. 
     Throughout the present specification and the accompanying claims the term “comprising” and “comprises” incorporates “consisting of” and “consists of”. That is, these words are intended to convey the possible inclusion of other elements or integers not specifically recited, where the context allows. 
     The term “specifically binds” as used throughout the present specification in relation to antigen binding proteins of the invention means that the antigen binding protein binds human BCMA (hBCMA) with no or insignificant binding to other human proteins. The term however does not exclude the fact that antigen binding proteins of the invention may also be cross-reactive with other forms of BCMA, for example primate BCMA. For example in one embodiment the antigen binding protein does not bind to TACI or BAFF-R. 
     The term “inhibits” as used throughout the present specification in relation to antigen binding proteins of the invention means that the biological activity of BCMA is reduced in the presence of the antigen binding proteins of the present invention in comparison to the activity of BCMA in the absence of such antigen binding proteins. Inhibition may be due but not limited to one or more of blocking ligand binding, preventing the ligand activating the receptor, and/or down regulating the BCMA. Inhibits can also refer to an antigen binding protein binding to BCMA and causing cell apoptosis or ADCC. The antibodies of the invention may neutralise the activity of the BCMA ligands BAFF and/or APRIL binding to BCMA. Levels of neutralisation can be measured in several ways, for example by use of the assays as set out in the examples below, for example in 4.4 in an H929 cell NFkB signalling assay. The BCMA ligands BAFF and APRIL are able to induce NFkB signalling and downstream events following binding to BCMA. The neutralisation of BCMA in this assay is measured by assessing the ability of anti-BCMA monoclonal antibodies to inhibit BAFF or APRIL driven NFkB induction. 
     If an antibody or antigen binding fragment thereof is capable of neutralisation then this is indicative of inhibition of the interaction between human BAFF or APRIL and BCMA. Antibodies which are considered to have neutralising activity against human BCMA would have an IC50 of less than 30 micrograms/ml, or less than 20 micrograms/ml, or less than 10 micrograms/ml, or less than 5 micrograms/ml or less than 1 micrograms/ml or less than 0.1 micrograms/ml in the H929 stimulation assay as set out in Example 4.4 
     “CDRs” are defined as the complementarity determining region amino acid sequences of an antibody which are the hypervariable domains of immunoglobulin heavy and light chains. There are three heavy chain and three light chain CDRs (or CDR regions) in the variable portion of an immunoglobulin. Thus, “CDRs” as used herein may refer to all three heavy chain CDRs, or all three light chain CDRs (or both all heavy and all light chain CDRs, if appropriate). 
     CDRs provide the majority of contact residues for the binding of the antibody to the antigen or epitope. CDRs of interest in this invention are derived from donor antibody variable heavy and light chain sequences, and include analogs of the naturally occurring CDRs, which analogs also share or retain the same antigen binding specificity and/or neutralizing ability as the donor antibody from which they were derived. 
     The CDR sequences of antibodies can be determined by the Kabat numbering system (Kabat et al; (Sequences of proteins of Immunological Interest NIH, 1987), alternatively they can be determined using the Chothia numbering system (Al-Lazikani et al., (1997) JMB 273,927-948), the contact definition method (MacCallum R. M., and Martin A. C. R. and Thornton J. M, (1996), Journal of Molecular Biology, 262 (5), 732-745) or any other established method for numbering the residues in an antibody and determining CDRs known to the skilled man in the art 
     Other numbering conventions for CDR sequences available to a skilled person include “AbM” (University of Bath) and “contact” (University College London) methods. The minimum overlapping region using at least two of the Kabat, Chothia, AbM and contact methods can be determined to provide the “minimum binding unit”. The minimum binding unit may be a sub-portion of a CDR. 
     Table A below represents one definition using each numbering convention for each CDR or binding unit. The Kabat numbering scheme is used in Table X to number the variable domain amino acid sequence. It should be noted that some of the CDR definitions may vary depending on the individual publication used.

     Throughout this specification, amino acid residues in antibody sequences are numbered according to the Kabat scheme. Similarly, the terms “CDR”, “CDRL1”, “CDRL2”, “CDRL3”, “CDRH1”, “CDRH2”, “CDRH3” follow the Kabat numbering system as set forth in Kabat et al; Sequences of proteins of Immunological Interest NIH, 1987. 
     The terms “Variant” refers to at least one, two or three amino acid changes in the sequence. These amino acid changes may be deletion, substitution or addition but are preferably substitution. In one such embodiment the substitutions are conservative substitutions. 
     In an alternative embodiment the variant sequence contains at least one substitution whilst retaining the canonical of the antigen binding protein. 
     The complementarity determining regions (CDRs) L1, L2, L3, H1 and H2 tend to structurally exhibit one of a finite number of main chain conformations. The particular canonical structure class of a CDR is defined by both the length of the CDR and by the loop packing, determined by residues located at key positions in both the CDRs and the framework regions (structurally determining residues or SDRs). Martin and Thornton (1996; J Mol Biol 263:800-815) have generated an automatic method to define the “key residue” canonical templates. Cluster analysis is used to define the canonical classes for sets of CDRs, and canonical templates are then identified by analysing buried hydrophobics, hydrogen-bonding residues, and e.g. conserved glycines. The CDRs of antibody sequences can be assigned to canonical classes by comparing the sequences to the key residue templates and scoring each template using identity or similarity matrices. 
     The terms “VH” and “VL” are used herein to refer to the heavy chain variable domain and light chain variable domain respectively of an antibody. 
     As used herein the term “domain” refers to a folded protein structure which has tertiary structure independent of the rest of the protein. Generally, domains are responsible for discrete functional properties of proteins and in many cases may be added, removed or transferred to other proteins without loss of function of the remainder of the protein and/or of the domain. An “antibody single variable domain” is a folded polypeptide domain comprising sequences characteristic of antibody variable domains. It therefore includes complete antibody variable domains and modified variable domains, for example, in which one or more loops have been replaced by sequences which are not characteristic of antibody variable domains, or antibody variable domains which have been truncated or comprise N- or C-terminal extensions, as well as folded fragments of variable domains which retain at least the binding activity and specificity of the full-length domain. 
     The phrase “immunoglobulin single variable domain” refers to an antibody variable domain (VH, VHH, VL) that specifically binds an antigen or epitope independently of a different V region or domain. An immunoglobulin single variable domain can be present in a format (e.g., homo- or hetero-multimer) with other, different variable regions or variable domains where the other regions or domains are not required for antigen binding by the single immunoglobulin variable domain (i.e., where the immunoglobulin single variable domain binds antigen independently of the additional variable domains). A “domain antibody” or “dAb” is the same as an “immunoglobulin single variable domain” which is capable of binding to an antigen as the term is used herein. An immunoglobulin single variable domain may be a human antibody variable domain, but also includes single antibody variable domains from other species such as rodent (for example, as disclosed in WO 00/29004), nurse shark and Camelid VHH dAbs. Camelid VHH are immunoglobulin single variable domain polypeptides that are derived from species including camel, llama, alpaca, dromedary, and guanaco, which produce heavy chain antibodies naturally devoid of light chains. Such VHH domains may be humanised according to standard techniques available in the art, and such domains are still considered to be “domain antibodies” according to the invention. As used herein “VH includes camelid VHH domains. NARV are another type of immunoglobulin single variable domain which were identified in cartilaginous fish including the nurse shark. These domains are also known as Novel Antigen Receptor variable region (commonly abbreviated to V(NAR) or NARV). For further details see Mol. Immunol. 44, 656-665 (2006) and US20050043519A. 
     The term “Epitope-binding domain” refers to a domain that specifically binds an antigen or epitope independently of a different V region or domain, this may be a domain antibody (dAb), for example a human, camelid or shark immunoglobulin single variable domain or it may be a domain which is a derivative of a scaffold selected from the group consisting of CTLA-4 (Evibody); lipocalin; Protein A derived molecules such as Z-domain of Protein A (Affibody, SpA), A-domain (Avimer/Maxibody); Heat shock proteins such as GroEl and GroES; 38eroxidise38g (trans-body); ankyrin repeat protein (DARPin); peptide aptamer; C-type lectin domain (Tetranectin); human γ-crystallin and human ubiquitin (affilins); PDZ domains; scorpion toxinkunitz type domains of human protease inhibitors; and fibronectin (adnectin); which has been subjected to protein engineering in order to obtain binding to a ligand other than the natural ligand. 
     CTLA-4 (Cytotoxic T Lymphocyte-associated Antigen 4) is a CD28-family receptor expressed on mainly CD4+ T-cells. Its extracellular domain has a variable domain-like Ig fold. Loops corresponding to CDRs of antibodies can be substituted with heterologous sequence to confer different binding properties. CTLA-4 molecules engineered to have different binding specificities are also known as Evibodies. For further details see Journal of Immunological Methods 248 (1-2), 31-45 (2001) 
     Lipocalins are a family of extracellular proteins which transport small hydrophobic molecules such as steroids, bilins, retinoids and lipids. They have a rigid β-sheet secondary structure with a number of loops at the open end of the conical structure which can be engineered to bind to different target antigens. Anticalins are between 160-180 amino acids in size, and are derived from lipocalins. For further details see Biochim Biophys Acta 1482: 337-350 (2000), U.S. Pat. No. 7,250,297B1 and US20070224633 
     An affibody is a scaffold derived from Protein A of  Staphylococcus aureus  which can be engineered to bind to antigen. The domain consists of a three-helical bundle of approximately 58 amino acids. Libraries have been generated by randomisation of surface residues. For further details see Protein Eng. Des. Sel. 17, 455-462 (2004) and EP1641818A1 
     Avimers are multidomain proteins derived from the A-domain scaffold family. The native domains of approximately 35 amino acids adopt a defined disulphide bonded structure. Diversity is generated by shuffling of the natural variation exhibited by the family of A-domains. For further details see Nature Biotechnology 23(12), 1556-1561 (2005) and Expert Opinion on Investigational Drugs 16(6), 909-917 (June 2007) 
     A Transferrin is a monomeric serum transport glycoprotein. Transferrins can be engineered to bind different target antigens by insertion of peptide sequences in a permissive surface loop. Examples of engineered transferrins scaffolds include the Trans-body. For further details see J. Biol. Chem 274, 24066-24073 (1999). 
     Designed Ankyrin Repeat Proteins (DARPins) are derived from Ankyrin which is a family of proteins that mediate attachment of integral membrane proteins to the cytoskeleton. A single ankyrin repeat is a 33 residue motif consisting of two α-helices and a β-turn. They can be engineered to bind different target antigens by randomising residues in the first α-helix and a β-turn of each repeat. Their binding interface can be increased by increasing the number of modules (a method of affinity maturation). For further details see J. Mol. Biol. 332, 489-503 (2003), PNAS 100(4), 1700-1705 (2003) and J. Mol. Biol. 369, 1015-1028 (2007) and US20040132028A1. 
     Fibronectin is a scaffold which can be engineered to bind to antigen. Adnectins consists of a backbone of the natural amino acid sequence of the 10 th  domain of the 15 repeating units of human fibronectin type III (FN3). Three loops at one end of the β-sandwich can be engineered to enable an Adnectin to specifically recognize a therapeutic target of interest. For further details see Protein Eng. Des. Sel. 18, 435-444 (2005), US20080139791, WO2005056764 and U.S. Pat. No. 6,818,418B1. 
     Peptide aptamers are combinatorial recognition molecules that consist of a constant scaffold protein, typically thioredoxin (TrxA) which contains a constrained variable peptide loop inserted at the active site. For further details see Expert Opin. Biol. Ther. 5, 783-797 (2005). 
     Microbodies are derived from naturally occurring microproteins of 25-50 amino acids in length which contain 3-4 cysteine bridges—examples of microproteins include KalataB1 and conotoxin and knottins. The microproteins have a loop which can be engineered to include up to 25 amino acids without affecting the overall fold of the microprotein. For further details of engineered knottin domains, see WO2008098796. 
     Other epitope binding domains include proteins which have been used as a scaffold to engineer different target antigen binding properties include human γ-crystallin and human ubiquitin (affilins), kunitz type domains of human protease inhibitors, PDZ-domains of the Ras-binding protein AF-6, scorpion toxins (charybdotoxin), C-type lectin domain (tetranectins) are reviewed in Chapter 7—Non-Antibody Scaffolds from Handbook of Therapeutic Antibodies (2007, edited by Stefan Dubel) and Protein Science 15:14-27 (2006). Epitope binding domains of the present invention could be derived from any of these alternative protein domains. 
     As used herein, the term “antigen-binding site” refers to a site on a protein which is capable of specifically binding to antigen, this may be a single domain, for example an epitope-binding domain, or it may be paired VH/VL domains as can be found on a standard antibody. In some embodiments of the invention single-chain Fv (ScFv) domains can provide antigen-binding sites. 
     The terms “mAbdAb” and dAbmAb” are used herein to refer to antigen-binding proteins of the present invention. The two terms can be used interchangeably, and are intended to have the same meaning as used herein. 
     The term “antigen binding protein” as used herein refers to antibodies, antibody fragments for example a domain antibody (dAb), ScFv, Fab, Fab2, and other protein constructs. Antigen binding molecules may comprise at least one Ig variable domain, for example antibodies, domain antibodies (dAbs), Fab, Fab′, F(ab′)2, Fv, ScFv, diabodies, mAbdAbs, affibodies, heteroconjugate antibodies or bispecific antibodies. In one embodiment the antigen binding molecule is an antibody. In another embodiment the antigen binding molecule is a dAb, i.e. an immunoglobulin single variable domain such as a VH, VHH or VL that specifically binds an antigen or epitope independently of a different V region or domain. Antigen binding molecules may be capable of binding to two targets, i.e. they may be dual targeting proteins. Antigen binding molecules may be a combination of antibodies and antigen binding fragments such as for example, one or more domain antibodies and/or one or more ScFvs linked to a monoclonal antibody. Antigen binding molecules may also comprise a non-Ig domain for example a domain which is a derivative of a scaffold selected from the group consisting of CTLA-4 (Evibody); lipocalin; Protein A derived molecules such as Z-domain of Protein A (Affibody, SpA), A-domain (Avimer/Maxibody); Heat shock proteins such as GroEl and GroES; 41eroxidise41g (trans-body); ankyrin repeat protein (DARPin); peptide aptamer; C-type lectin domain (Tetranectin); human γ-crystallin and human ubiquitin (affilins); PDZ domains; scorpion toxinkunitz type domains of human protease inhibitors; and fibronectin (adnectin); which has been subjected to protein engineering in order to obtain binding to OSM. As used herein “antigen binding protein” will be capable of antagonising and/or neutralising human OSM. In addition, an antigen binding protein may inhibit and or block OSM activity by binding to OSM and preventing a natural ligand from binding and/or activating the gp130 receptor. 
     The term “Effector Function” as used herein is meant to refer to one or more of Antibody dependent cell mediated cytotoxic activity (ADCC), Complement-dependent cytotoxic activity (CDC) mediated responses, Fc-mediated phagocytosis and antibody recycling via the FcRn receptor. For IgG antibodies, effector functionalities including ADCC and ADCP are mediated by the interaction of the heavy chain constant region with a family of Fcγ receptors present on the surface of immune cells. In humans these include FcγRI (CD64), FcγRII (CD32) and FcγRIII (CD16). Interaction between the antigen binding protein bound to antigen and the formation of the Fc/Fcγ complex induces a range of effects including cytotoxicity, immune cell activation, phagocytosis and release of inflammatory cytokines. The interaction between the constant region of an antigen binding protein and various Fc receptors (FcR) is believed to mediate the effector functions of the antigen binding protein. Significant biological effects can be a consequence of effector functionality, in particular, antibody-dependent cellular cytotoxicity (ADCC), fixation of complement (complement dependent cytotoxicity or CDC), and half-life/clearance of the antigen binding protein. Usually, the ability to mediate effector function requires binding of the antigen binding protein to an antigen and not all antigen binding proteins will mediate every effector function. 
     Effector function can be measured in a number of ways including for example via binding of the FcγRIII to Natural Killer cells or via FcγR1 to monocytes/macrophages to measure for ADCC effector function. For example an antigen binding protein of the present invention can be assessed for ADCC effector function in a Natural Killer cell assay. Examples of such assays can be found in Shields et al, 2001 The Journal of Biological Chemistry, Vol. 276, p6591-6604; Chappel et al, 1993 The Journal of Biological Chemistry, Vol 268, p25124-25131; Lazar et al, 2006 PNAS, 103; 4005-4010. 
     Examples of assays to determine CDC function include that described in 1995 J Imm Meth 184:29-38. 
     Some isotypes of human constant regions, in particular IgG4 and IgG2 isotypes, essentially lack the functions of a) activation of complement by the classical pathway; and b) antibody-dependent cellular cytotoxicity. Various modifications to the heavy chain constant region of antigen binding proteins may be carried out depending on the desired effector property. IgG1 constant regions containing specific mutations have separately been described to reduce binding to Fc receptors and therefore reduce ADCC and CDC (Duncan et al. Nature 1988, 332; 563-564; Lund et al. J. Immunol. 1991, 147; 2657-2662; Chappel et al. PNAS 1991, 88; 9036-9040; Burton and Woof, Adv. Immunol. 1992, 51; 1-84; Morgan et al., Immunology 1995, 86; 319-324; Hezareh et al., J. Virol. 2001, 75 (24); 12161-12168). 
     In one embodiment of the present invention there is provided an antigen binding protein comprising a constant region such that the antigen binding protein has reduced ADCC and/or complement activation or effector functionality. In one such embodiment the heavy chain constant region may comprise a naturally disabled constant region of IgG2 or IgG4 isotype or a mutated IgG1 constant region. Examples of suitable modifications are described in EP0307434. One example comprises the substitutions of alanine residues at positions 235 and 237 (EU index numbering). 
     Human IgG1 constant regions containing specific mutations or altered glycosylation on residue Asn297 have also been described to enhance binding to Fc receptors. In some cases these mutations have also been shown to enhance ADCC and CDC (Lazar et al. PNAS 2006, 103; 4005-4010; Shields et al. J Biol Chem 2001, 276; 6591-6604; Nechansky et al. Mol Immunol, 2007, 44; 1815-1817). 
     In one embodiment of the present invention, such mutations are in one or more of positions selected from 239, 332 and 330 (IgG1), or the equivalent positions in other IgG isotypes. Examples of suitable mutations are S239D and I332E and A330L. In one embodiment the antigen binding protein of the invention herein described is mutated at positions 239 and 332, for example S239D and I332E or in a further embodiment it is mutated at three or more positions selected from 239 and 332 and 330, for example S239D and I332E and A330L. (EU index numbering). 
     In an alternative embodiment of the present invention, there is provided an antigen binding protein comprising a heavy chain constant region with an altered glycosylation profile such that the antigen binding protein has enhanced effector function. For example, wherein the antigen binding protein has enhanced ADCC or enhanced CDC or wherein it has both enhanced ADCC and CDC effector function. Examples of suitable methodologies to produce antigen binding proteins with an altered glycosylation profile are described in WO2003011878, WO2006014679 and EP1229125, all of which can be applied to the antigen binding proteins of the present invention. 
     The present invention also provides a method for the production of an antigen binding protein according to the invention comprising the steps of: 
     a) culturing a recombinant host cell comprising an expression vector comprising the isolated nucleic acid as described herein, wherein the FUT8 gene encoding alpha-1,6-fucosyltransferase has been inactivated in the recombinant host cell; and 
     b) recovering the antigen binding protein. 
     Such methods for the production of antigen binding proteins can be performed, for example, using the POTELLIGENT™ technology system available from BioWa, Inc. (Princeton, N.J.) in which CHOK1SV cells lacking a functional copy of the FUT8 gene produce monoclonal antibodies having enhanced antibody dependent cell mediated cytotoxicity (ADCC) activity that is increased relative to an identical monoclonal antibody produced in a cell with a functional FUT8 gene. Aspects of the POTELLIGENT™ technology system are described in U.S. Pat. Nos. 7,214,775, 6,946,292, WO0061739 and WO0231240 all of which are incorporated herein by reference. Those of ordinary skill in the art will also recognize other appropriate systems. 
     In one embodiment of the present invention there is provided an antigen binding protein comprising a chimaeric heavy chain constant region for example an antigen binding protein comprising a chimaeric heavy chain constant region with at least one CH2 domain from IgG3 such that the antigen binding protein has enhanced effector function, for example wherein it has enhanced ADCC or enhanced CDC, or enhanced ADCC and CDC functions. In one such embodiment, the antigen binding protein may comprise one CH2 domain from IgG3 or both CH2 domains may be from IgG3. 
     Also provided is a method of producing an antigen binding protein according to the invention comprising the steps of: 
     a) culturing a recombinant host cell comprising an expression vector comprising an isolated nucleic acid as described herein wherein the expression vector comprises a nucleic acid sequence encoding an Fc domain having both IgG1 and IgG3 Fc domain amino acid residues; and 
     b) recovering the antigen binding protein. 
     Such methods for the production of antigen binding proteins can be performed, for example, using the COMPLEGENT™ technology system available from BioWa, Inc. (Princeton, N.J.) and Kyowa Hakko Kogyo (now, Kyowa Hakko Kirin Co., Ltd.) Co., Ltd. In which a recombinant host cell comprising an expression vector in which a nucleic acid sequence encoding a chimeric Fc domain having both IgG1 and IgG3 Fc domain amino acid residues is expressed to produce an antigen binding protein having enhanced complement dependent cytotoxicity (CDC) activity that is increased relative to an otherwise identical antigen binding protein lacking such a chimeric Fc domain. Aspects of the COMPLEGENT™ technology system are described in WO2007011041 and US20070148165 each of which are incorporated herein by reference. In an alternative embodiment CDC activity may be increased by introducing sequence specific mutations into the Fc region of an IgG chain. Those of ordinary skill in the art will also recognize other appropriate systems. 
     It will be apparent to those skilled in the art that such modifications may not only be used alone but may be used in combination with each other in order to further enhance effector function. 
     In one such embodiment of the present invention there is provided an antigen binding protein comprising a heavy chain constant region which comprises a mutated and chimaeric heavy chain constant region for example wherein an antigen binding protein comprising at least one CH2 domain from IgG3 and one CH2 domain from IgG1, wherein the IgG1 CH2 domain has one or more mutations at positions selected from 239 and 332 and 330 (for example the mutations may be selected from S239D and I332E and A330L) such that the antigen binding protein has enhanced effector function, for example wherein it has one or more of the following functions, enhanced ADCC or enhanced CDC, for example wherein it has enhanced ADCC and enhanced CDC. In one embodiment the IgG1 CH2 domain has the mutations S239D and I332E. 
     In an alternative embodiment of the present invention there is provided an antigen binding protein comprising a chimaeric heavy chain constant region and which has an altered glycosylation profile. In one such embodiment the heavy chain constant region comprises at least one CH2 domain from IgG3 and one CH2 domain from IgG1 and has an altered glycosylation profile such that the ratio of fucose to mannose is 0.8:3 or less, for example wherein the antigen binding protein is defucosylated so that said antigen binding protein has an enhanced effector function in comparison with an equivalent antigen binding protein with an immunoglobulin heavy chain constant region lacking said mutations and altered glycosylation profile, for example wherein it has one or more of the following functions, enhanced ADCC or enhanced CDC, for example wherein it has enhanced ADCC and enhanced CDC. 
     In an alternative embodiment the antigen binding protein has at least one IgG3 CH2 domain and at least one heavy chain constant domain from IgG1 wherein both IgG CH2 domains are mutated in accordance with the limitations described herein. 
     In one aspect of the invention there is provided a method of producing an antigen binding protein according to the invention described herein comprising the steps of: 
     a) culturing a recombinant host cell containing an expression vector containing an isolated nucleic acid as described herein, said expression vector further comprising a Fc nucleic acid sequence encoding a chimeric Fc domain having both IgG1 and IgG3 Fc domain amino acid residues, and wherein the FUT8 gene encoding alpha-1,6-fucosyltransferase has been inactivated in the recombinant host cell; and 
     b) recovering the antigen binding protein. 
     Such methods for the production of antigen binding proteins can be performed, for example, using the ACCRETAMAB™ technology system available from BioWa, Inc. (Princeton, N.J.) which combines the POTELLIGENT™ and COMPLEGENT™ technology systems to produce an antigen binding protein having both ADCC and CDC enhanced activity that is increased relative to an otherwise identical monoclonal antibody lacking a chimeric Fc domain and which has fucose on the oligosaccharide. 
     In yet another embodiment of the present invention there is provided an antigen binding protein comprising a mutated and chimeric heavy chain constant region wherein said antigen binding protein has an altered glycosylation profile such that the antigen binding protein has enhanced effector function, for example wherein it has one or more of the following functions, enhanced ADCC or enhanced CDC.

In one embodiment the heavy chain constant region has an altered glycosylation profile such that the ratio of fucose to mannose is 0.8:3 or less for example the antigen binding protein is defucosylated, so that said antigen binding protein has an enhanced effector function in comparison with an equivalent non-chimaeric antigen binding protein or with an immunoglobulin heavy chain constant region lacking said mutations and altered glycosylation profile. 
     Immunoconjugates 
     Also provided is an immunoconjugate (interchangeably referred to as “antibody-drug conjugates,” or “ADCs”) comprising an antigen binding protein according to the invention as herein described including, but not limited to, an antibody conjugated to one or more cytotoxic agents, such as a chemotherapeutic agent, a drug, a growth inhibitory agent, a toxin (e.g., a protein toxin, an enzymatically active toxin of bacterial, fungal, plant, or animal origin, or fragments thereof), or a radioactive isotope (i.e., a radioconjugate). 
     Immunoconjugates have been used for the local delivery of cytotoxic agents, i.e., drugs that kill or inhibit the growth or proliferation of cells, in the treatment of cancer (Lambert, J. (2005) Curr. Opinion in Pharmacology 5:543-549; Wu et al. (2005) Nature Biotechnology 23(9):1137-1146; Payne, G. (2003) i 3:207-212; Syrigos and Epenetos (1999) Anticancer Research 19:605-614; Niculescu-Duvaz and Springer (1997) Adv. Drug Deliv. Rev. 26:151-172; U.S. Pat. No. 4,975,278). Immunoconjugates allow for the targeted delivery of a drug moiety to a tumor, and intracellular accumulation therein, where systemic administration of unconjugated drugs may result in unacceptable levels of toxicity to normal cells as well as the tumor cells sought to be eliminated (Baldwin et al., Lancet (Mar. 15, 1986) pp. 603-05; Thorpe (1985) “Antibody Carriers Of Cytotoxic Agents In Cancer Therapy: A Review,” in Monoclonal Antibodies &#39;84: Biological And Clinical Applications (A. Pinchera et al., eds) pp. 475-506. Both polyclonal antibodies and monoclonal antibodies have been reported as useful in these strategies (Rowland et al., (1986) Cancer Immunol. Immunother. 21:183-87). Drugs used in these methods include daunomycin, doxorubicin, methotrexate, and vindesine (Rowland et al., (1986) supra). Toxins used in antibody-toxin conjugates include bacterial toxins such as diphtheria toxin, plant toxins such as ricin, small molecule toxins such as geldanamycin (Mandler et al (2000) J. Nat. Cancer Inst. 92(19):1573-1581; Mandler et al (2000) Bioorganic &amp; Med. Chem. Letters 10:1025-1028; Mandler et al (2002) Bioconjugate Chem. 13:786-791), maytansinoids (EP 1391213; Liu et al., (1996) Proc. Natl. Acad. Sci. USA 93:8618-8623), and calicheamicin (Lode et al (1998) Cancer Res. 58:2928; Hinman et al (1993) Cancer Res. 53:3336-3342). 
     In one embodiment, the present invention includes immunoconjugates having the following general structure: 
       ABP-((Linker) n -Ctx) m    
     Wherein ABP is an antigen binding protein 
     Linker is either absent or any a cleavable or non-cleavable linker described herein 
     Ctx is any cytotoxic agent described herein 
     n is 0, 1, 2, or 3 and 
     m is 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10. 
     Examples of antibodies linked by an MC linker with auristatins such as MMAE and MMAF are depicted in the following structures: 
     
       
         
         
             
             
         
       
     
     In certain embodiments, an immunoconjugate comprises an antigen binding protein, including but not limited to, an antibody and a chemotherapeutic agent or other toxin. Chemotherapeutic agents useful in the generation of immunoconjugates are described herein. Enzymatically active toxins and fragments thereof that can be used include diphtheria A chain, nonbinding active fragments of diphtheria toxin, exotoxin A chain (from  Pseudomonas aeruginosa ), ricin A chain, abrin A chain, modeccin A chain, alpha-sarcin,  Aleurites fordii  proteins, dianthin proteins,  Phytolaca americana  proteins (PAPI, PAPII, and PAP-S),  Momordica charantia  inhibitor, curcin, crotin,  Sapaonaria officinalis  inhibitor, gelonin, mitogellin, restrictocin, phenomycin, enomycin, and the tricothecenes. See, e.g., WO 93/21232 published Oct. 28, 1993. A variety of radionuclides are available for the production of radioconjugated antibodies. Examples include  211 At,  212 Bi,  131 I,  131 In,  90 Y, and  186 Re. 
     Antigen binding proteins of the present invention may also be conjugated to one or more toxins, including, but not limited to, a calicheamicin, maytansinoids, dolastatins, aurostatins, a trichothecene, and CC1065, and the derivatives of these toxins that have toxin activity. Suitable cytotoxic agents include, but are not limited to, an auristatin including dovaline-valine-dolaisoleunine-dolaproine-phenylalanine (MMAF) and monomethyl auristatin E (MMAE) as well as ester forms of MMAE, a DNA minor groove binding agent, a DNA minor groove alkylating agent, an enediyne, a lexitropsin, a duocarmycin, a taxane, including paclitaxel and docetaxel, a puromycin, a dolastatin, a maytansinoid, and a vinca alkaloid. Specific cytotoxic agents include topotecan, morpholino-doxorubicin, rhizoxin, cyanomorpholino-doxorubicin, dolastatin-10, echinomycin, combretatstatin, chalicheamicin, maytansine, DM-1, DM-4, netropsin. Other suitable cytotoxic agents include anti-tubulin agents, such as an auristatin, a vinca alkaloid, a podophyllotoxin, a taxane, a baccatin derivative, a cryptophysin, a maytansinoid, a combretastatin, or a dolastatin. Antitubulin agent include dimethylvaline-valine-dolaisoleuine-dolaproine-phenylalanine-p-phenylened-iamine (AFP), MMAF, MMAE, auristatin E, vincristine, vinblastine, vindesine, vinorelbine, VP-16, camptothecin, paclitaxel, docetaxel, epothilone A, epothilone B, nocodazole, colchicines, colcimid, estramustine, cemadotin, discodermolide, maytansine, DM-1, DM-4 or eleutherobin. 
     Antibody drug conjugates were produced by conjugating the small molecule anti-tubulin agent monomethylauristatin E (MMAE) or monomethylauristatin F (MMAF) to the antibodies. In the case of MMAE the linker consists of a thiol-reactive maleimide, a caproyl spacer, the dipeptide valine-citrulline, and p-aminobenzyloxycarbonyl, a self-immolative fragmenting group. In the case of MMAF a protease-resistant maleimidocaproyl linker is used. The conjugation process leads to heterogeneity in drug-antibody attachment, varying in both the number of drugs bound to each antibody molecule (mole ratio [MR]), and the site of attachment. The most prevalent species is the material with an MR=4; less prevalent are materials with MR of 0, 2, 6, and 8. The overall average drug-to-antibody MR is approximately 4. 
     Production of Immunoconjugates 
     The points of attachment are cysteines produced by mild reduction of the interchain disulfides of the antibody which is carried out whilst antibodies are immobilised on Protein G affinity resin (thus enabling the use of large reagent excesses without intermediate purifications). While immobilized, a large excess of TCEP will fully reduce the interchain disulfides but has no impact upon the binding of the antibody to the resin.
         The number of thiols per antibody generated by this procedure depends upon the source and isotype of the antibodies. For example, human (and mouse-human chimeric) IgG1s have 4 reducible disulfides, and thus generate 8 thiols upon full reduction, whereas murine IgG1s have 5 reducible disulfides and produce 10 thiols. If ADCs with the maximal drug loading (e.g., 10 drugs per antibody for the murine IgG1s) are desired, then the maleimido-drug-linker can simply be added to the immobilized antibodies in sufficient excess to ensure complete conjugation. However, ADCs with fewer drugs per antibody can also be prepared from fully reduced antibodies by including a biologically inert capping agent such as N-ethyl maleimide (NEM) which occupies some of the available thiols on the antibody. When the maleimido-drug-linker and the capping agent are added simultaneously to the fully reduced antibody and in large excess (at least 3-fold), the two maleimide electrophiles compete for the limiting number of available thiols. In this fashion, the drug loading is determined by the relative thiol reaction rates of the drug-linker and capping agent, and thus can be considered to be under kinetic control. The relative reaction rates of maleimido-drug-linkers do vary significantly, and thus the molar ratio of drug-linker to NEM present in a reaction mix must be determined empirically to arrive at a panel of ADCs with a desired level of drug loading. The mole fraction of the drug linkers SGD-1006 (vcMMAE) and SGD-1269 (mcMMAF) in NEM mixtures which yield ADCs with approximately 4 drugs per antibody are summarized in Table 2 for common human and murine IgG isotypes.       

     Auristatins and Dolastatins 
     In some embodiments, the immunoconjugate comprises an antigen binding protein or antibody conjugated to dolastatins or dolostatin peptidic analogs and derivatives, the auristatins (U.S. Pat. Nos. 5,635,483; 5,780,588). Dolastatins and auristatins have been shown to interfere with microtubule dynamics, GTP hydrolysis, and nuclear and cellular division (Woyke et al. (2001) Antimicrob. Agents and Chemother. 45(12):3580-3584) and have anticancer (U.S. Pat. No. 5,663,149) and antifungal activity (Pettit et al. (1998) Antimicrob. Agents Chemother. 42:2961-2965). The dolastatin or auristatin (which are pentapeptide derivatives of dolastatins) drug moiety may be attached to the antibody through the N (amino) terminus or the C (carboxyl) terminus of the peptidic drug moiety (WO 02/088172). 
     Exemplary auristatin embodiments include the N-terminus linked monomethylauristatin drug moieties DE and DF, disclosed in “Monomethylvaline Compounds Capable of Conjugation to Ligands,” U.S. Pat. No. 7,498,298, the disclosure of which is expressly incorporated by reference in its entirety. As used herein, the abbreviation “MMAE” refers to monomethyl auristatin E. As used herein the abbreviation “MMAF” refers to dovaline-valine-dolaisoleuine-dolaproine-phenylalanine. 
     Typically, peptide-based drug moieties can be prepared by forming a peptide bond between two or more amino acids and/or peptide fragments. Such peptide bonds can be prepared, for example, according to the liquid phase synthesis method (see E. Schroder and K. Lubke, “The Peptides,” volume 1, pp 76-136, 1965, Academic Press) that is well known in the field of peptide chemistry. The auristatin/dolastatin drug moieties may be prepared according to the methods of: U.S. Pat. Nos. 5,635,483; 5,780,588; Pettit et al. (1989) J. Am. Chem. Soc. 111:5463-5465; Pettit et al. (1998) Anti-Cancer Drug Design 13:243-277; Pettit, G. R., et al. Synthesis, 1996, 719-725; and Pettit et al. (1996) J. Chem. Soc. Perkin Trans. 15:859-863. See also Doronina (2003) Nat Biotechnol 21(7):778-784; “Monomethylvaline Compounds Capable of Conjugation to Ligands,” U.S. Pat. No. 7,498,298, filed Nov. 5, 2004, hereby incorporated by reference in its entirety (disclosing, e.g., linkers and methods of preparing monomethylvaline compounds such as MMAE and MMAF conjugated to linkers). Biologically active organic compounds which act as cytotoxic agents, specifically pentapeptides, are disclosed in U.S. Pat. Nos. 6,884,869; 7,498,298; 7,098,308; 7,256,257; and 7,423,116. Monoclonal antibodies linked with MMAE and MMAF as well as various derivatives of auristatins and methods of making them are described in U.S. Pat. No. 7,964,566. 
     Examples of auristatins include MMAE and MMAF the structures of which are shown below: 
     
       
         
         
             
             
         
       
     
     Maytansine and Maytansinoids 
     Maytansinoids are mitototic inhibitors which act by inhibiting tubulin polymerization. Maytansine was first isolated from the east African shrub  Maytenus serrata  (U.S. Pat. No. 3,896,111). Subsequently, it was discovered that certain microbes also produce maytansinoids, such as maytansinol and C-3 maytansinol esters (U.S. Pat. No. 4,151,042). Highly cytotoxic maytansinoid drugs can be prepared from ansamitocin precursors produced by fermentation of microorganisms such as  Actinosynnema . Methods for isolating ansamitocins are described in U.S. Pat. No. 6,573,074. Synthetic maytansinol and derivatives and analogues thereof are disclosed, for example, in U.S. Pat. Nos. 4,137,230; 4,248,870; 4,256,746; 4,260,608; 4,265,814; 4,294,757; 4,307,016; 4,308,268; 4,308,269; 4,309,428; 4,313,946; 4,315,929; 4,317,821; 4,322,348; 4,331,598; 4,361,650; 4,364,866; 4,424,219; 4,450,254; 4,362,663; and 4,371,533. 
     Antibody-maytansinoid conjugates are prepared by chemically linking an antibody to a maytansinoid molecule without significantly diminishing the biological activity of either the antibody or the maytansinoid molecule. See, e.g., U.S. Pat. No. 5,208,020. An average of 3-4 maytansinoid molecules conjugated per antibody molecule has shown efficacy in enhancing cytotoxicity of target cells without negatively affecting the function or solubility of the antibody, although even one molecule of toxin/antibody would be expected to enhance cytotoxicity over the use of naked antibody. Maytansinoids are well known in the art and can be synthesized by known techniques or isolated from natural sources. Suitable maytansinoids are disclosed, for example, in U.S. Pat. No. 5,208,020 and in the other patents and nonpatent publications referred to hereinabove. Maytansinoids are maytansinol and maytansinol analogues modified in the aromatic ring or at other positions of the maytansinol molecule, such as various maytansinol esters. Methods for preparing matansinoids for linkage with antibodies are disclosed in U.S. Pat. Nos. 6,570,024 and 6,884,874. 
     Calicheamicin 
     The calicheamicin family of antibiotics is capable of producing double-stranded DNA breaks at sub-picomolar concentrations. For the preparation of conjugates of the calicheamicin family, see U.S. Pat. Nos. 5,712,374, 5,714,586, 5,739,116, 5,767,285, 5,770,701, 5,770,710, 5,773,001, 5,877,296 (all to American Cyanamid Company). Structural analogues of calicheamicin which may be used include, but are not limited to, .gamma.1I, .alpha.2I, .alpha.3I, N-acetyl-.gamma.1I, PSAG and .theta.I1 (Hinman et al., Cancer Research 53:3336-3342 (1993), Lode et al., Cancer Research 58:2925-2928 (1998) and the aforementioned U.S. patents to American Cyanamid). Another anti-tumor drug that the antibody can be conjugated is QFA which is an antifolate. Both calicheamicin and QFA have intracellular sites of action and do not readily cross the plasma membrane. Therefore, cellular uptake of these agents through antibody mediated internalization greatly enhances their cytotoxic effects. 
     Other Cytotoxic Agents 
     Other antitumor agents that can be conjugated to the antibodies include BCNU, streptozoicin, vincristine and 5-fluorouracil, the family of agents known collectively LL-E33288 complex described in U.S. Pat. Nos. 5,053,394, 5,770,710, as well as esperamicins (U.S. Pat. No. 5,877,296). 
     Enzymatically active toxins and fragments thereof which can be used include diphtheria A chain, nonbinding active fragments of diphtheria toxin, exotoxin A chain (from  Pseudomonas aeruginosa ), ricin A chain, abrin A chain, modeccin A chain, alpha-sarcin,  Aleurites fordii  proteins, dianthin proteins,  Phytolaca americana  proteins (PAPI, PAPII, and PAP-S),  Momordica charantia  inhibitor, curcin, crotin,  Sapaonaria officinalis  inhibitor, gelonin, mitogellin, restrictocin, phenomycin, enomycin and the tricothecenes. See, for example, WO 93/21232 published Oct. 28, 1993. 
     The present invention further contemplates an immunoconjugate formed between an antibody and a compound with nucleolytic activity (e.g., a ribonuclease or a DNA endonuclease such as a deoxyribonuclease; DNase). 
     For selective destruction of the tumor, the antibody may comprise a highly radioactive atom. A variety of radioactive isotopes are available for the production of radioconjugated antibodies. Examples include At211, I131, I125, Y90, Re186, Re188, Sm153, Bi212, P32, Pb212 and radioactive isotopes of Lu. When the conjugate is used for detection, it may comprise a radioactive atom for scintigraphic studies, for example tc99m or 1123, or a spin label for nuclear magnetic resonance (NMR) imaging (also known as magnetic resonance imaging, mri), such as iodine-123 again, iodine-131, indium-111, fluorine-19, carbon-13, nitrogen-15, oxygen-17, gadolinium, manganese or iron. 
     The radio- or other labels may be incorporated in the conjugate in known ways. For example, the peptide may be biosynthesized or may be synthesized by chemical amino acid synthesis using suitable amino acid precursors involving, for example, fluorine-19 in place of hydrogen. Labels such as tc99m or 1123, Re186, Re188 and In111 can be attached via a cysteine residue in the peptide. Yttrium-90 can be attached via a lysine residue. The IODOGEN method (Fraker et al. (1978) Biochem. Biophys. Res. Commun. 80: 49-57) can be used to incorporate iodine-123. “Monoclonal Antibodies in Immunoscintigraphy” (Chatal, CRC Press 1989) describes other methods in detail. 
     Preparation of ADCs 
     In antibody drug conjugates, the antibody can be conjugated directly to the cytotoxic agent or via a linker. Suitable linkers include, for example, cleavable and non-cleavable linkers. A cleavable linker is typically susceptible to cleavage under intracellular conditions. Suitable cleavable linkers include, for example, a peptide linker cleavable by an intracellular protease, such as lysosomal protease or an endosomal protease. In exemplary embodiments, the linker can be a dipeptide linker, such as a valine-citrulline (val-cit) or a phenylalanine-lysine (phe-lys) linker. Other suitable linkers include linkers hydrolyzable at a pH of less than 5.5, such as a hydrazone linker. Additional suitable cleavable linkers include disulfide linkers. 
     Bristol-Myers Squibb has described particular lysosomal enzyme-cleavable antitumor drug conjugates. See, for example, U.S. Pat. No. 6,214,345. Seattle Genetics has published applications U.S. Pat. Appl. 2003/0096743 and U.S. Pat. Appl. 2003/0130189, which describe p-aminobenzylethers in drug delivery agents. The linkers described in these applications are limited to aminobenzyl ether compositions. 
     Conjugates of the antigen binding protein and cytotoxic agent may be made using a variety of bifunctional protein coupling agents such as N-succinimidyl-3-(2-pyridyldithio)propionate (SPDP), succinimidyl-4-(N-maleimidomethyl) cyclohexane-1-carboxylate (SMCC), iminothiolane (IT), bifunctional derivatives of imidoesters (such as dimethyl adipimidate HCl), active esters (such as disuccinimidyl suberate), aldehydes (such as glutaraldehyde), bis-azido compounds (such as bis(p-azidobenzoyl) hexanediamine), bis-diazonium derivatives (such as bis-(p-diazoniumbenzoyl)-ethylenediamine), diisocyanates (such as toluene 2,6-diisocyanate), and bis-active fluorine compounds (such as 1,5-difluoro-2,4-dinitrobenzene). 
     Additionally the linker may be composed of one or more linker components. Exemplary linker components include 6-maleimidocaproyl (“MC”), maleimidopropanoyl (“MP”), valine-citrulline (“val-cit”), alanine-phenylalanine (“ala-phe”), p-aminobenzyloxycarbonyl (“PAB”), N-Succinimidyl 4-(2-pyridylthio)pentanoate (“SPP”), N-Succinimidyl 4-(N-maleimidomethyl)cyclohexane-1 carboxylate (“SMCC”), and N-Succinimidyl (4-iodo-acetyl)aminobenzoate (“SIAB”). Additional linker components are known in the art and some are described herein. See also “Monomethylvaline Compounds Capable of Conjugation to Ligands,” U.S. Pat. No. 7,498,298, filed Nov. 5, 2004, the contents of which are hereby incorporated by reference in its entirety. 
     Linkers may also comprises amino acids and/or amino acid analogs. Amino acid linker components include a dipeptide, a tripeptide, a tetrapeptide or a pentapeptide. Exemplary dipeptides include: valine-citrulline (vc or val-cit), alanine-phenylalanine (af or ala-phe). Exemplary tripeptides include: glycine-valine-citrulline (gly-val-cit) and glycine-glycine-glycine (gly-gly-gly). Amino acid residues which comprise an amino acid linker component include those occurring naturally, as well as minor amino acids and non-naturally occurring amino acid analogs, such as citrulline. Amino acid linker components can be designed and optimized in their selectivity for enzymatic cleavage by a particular enzyme, for example, a tumor-associated protease, cathepsin B, C and D, or a plasmin protease. 
     Antigen binding proteins and antibodies may be made reactive for conjugation with linker reagents. Nucleophilic groups on antibodies include, but are not limited to: (i) N-terminal amine groups, (ii) side chain amine groups, e.g., lysine, (iii) side chain thiol groups, e.g. cysteine, and (iv) sugar hydroxyl or amino groups where the antibody is glycosylated. Amine, thiol, and hydroxyl groups are nucleophilic and capable of reacting to form covalent bonds with electrophilic groups on linker moieties and linker reagents including: (i) active esters such as NHS esters, HOBt esters, haloformates, and acid halides; (ii) alkyl and benzyl halides such as haloacetamides; (iii) aldehydes, ketones, carboxyl, and maleimide groups. Certain antibodies have reducible interchain disulfides, i.e. cysteine bridges. Antibodies may be made reactive for conjugation with linker reagents by treatment with a reducing agent such as DTT (dithiothreitol). Each cysteine bridge will thus form, theoretically, two reactive thiol nucleophiles. Additional nucleophilic groups can be introduced into antibodies through the reaction of lysines with 2-iminothiolane (Traut&#39;s reagent) resulting in conversion of an amine into a thiol. Reactive thiol groups may be introduced into the antibody (or fragment thereof) by introducing one, two, three, four, or more cysteine residues (e.g., preparing mutant antibodies comprising one or more non-native cysteine amino acid residues). 
     Antigen binding proteins and antibodies may also be modified to introduce electrophilic moieties, which can react with nucleophilic substituents on the linker reagent or drug. The sugars of glycosylated antibodies may be oxidized, e.g. with periodate oxidizing reagents, to form aldehyde or ketone groups which may react with the amine group of linker reagents or drug moieties. The resulting imine Schiff base groups may form a stable linkage, or may be reduced, e.g., by borohydride reagents to form stable amine linkages. In one embodiment, reaction of the carbohydrate portion of a glycosylated antibody with either galactose oxidase or sodium meta-periodate may yield carbonyl (aldehyde and ketone) groups in the protein that can react with appropriate groups on the drug (Hermanson, Bioconjugate Techniques). In another embodiment, proteins containing N-terminal serine or threonine residues can react with sodium meta-periodate, resulting in production of an aldehyde in place of the first amino acid (Geoghegan &amp; Stroh, (1992) Bioconjugate Chem. 3:138-146; U.S. Pat. No. 5,362,852). Such aldehydes can be reacted with a drug moiety or linker nucleophile. 
     Nucleophilic groups on a drug moiety include, but are not limited to: amine, thiol, hydroxyl, hydrazide, oxime, hydrazine, thiosemicarbazone, hydrazine carboxylate, and arylhydrazide groups capable of reacting to form covalent bonds with electrophilic groups on linker moieties and linker reagents including: (i) active esters such as NHS esters, HOBt esters, haloformates, and acid halides; (ii) alkyl and benzyl halides such as haloacetamides; (iii) aldehydes, ketones, carboxyl, and maleimide groups. 
     In some embodiments, the linker is cleavable by a cleaving agent that is present in the intracellular environment (e.g., within a lysosome or endosome or caveolea). The linker can be, e.g., a peptidyl linker that is cleaved by an intracellular peptidase or protease enzyme, including, but not limited to, a lysosomal or endosomal protease. Typically, the peptidyl linker is at least two amino acids long or at least three amino acids long. Cleaving agents can include cathepsins B and D and plasmin, all of which are known to hydrolyze dipeptide drug derivatives resulting in the release of active drug inside target cells (see, e.g., Dubowchik and Walker, 1999, Pharm. Therapeutics 83:67-123). Peptidyl linkers may be cleavable by enzymes that are present cells. For example, a peptidyl linker that is cleavable by the thiol-dependent protease cathepsin-B, which is highly expressed in cancerous tissue, can be used (e.g., a Phe-Leu or a Gly-Phe-Leu-Gly (SEQ ID NO:50) linker). Other such linkers are described, e.g., in U.S. Pat. No. 6,214,345. In specific embodiments, the peptidyl linker cleavable by an intracellular protease is a Val-Cit linker or a Phe-Lys linker (see, e.g., U.S. Pat. No. 6,214,345, which describes the synthesis of doxorubicin with the val-cit linker). One advantage of using intracellular proteolytic release of the therapeutic agent is that the agent is typically attenuated when conjugated and the serum stabilities of the conjugates are typically high. 
     In other embodiments, the cleavable linker is pH-sensitive, i.e., sensitive to hydrolysis at certain pH values. Typically, the pH-sensitive linker hydrolyzable under acidic conditions. For example, an acid-labile linker that is hydrolyzable in the lysosome (e.g., a hydrazone, semicarbazone, thiosemicarbazone, cis-aconitic amide, orthoester, acetal, ketal, or the like) can be used. (See, e.g., U.S. Pat. Nos. 5,122,368; 5,824,805; 5,622,929; Dubowchik and Walker, 1999, Pharm. Therapeutics 83:67-123; Neville et al., 1989, Biol. Chem. 264:14653-14661.) Such linkers are relatively stable under neutral pH conditions, such as those in the blood, but are unstable at below pH 5.5 or 5.0, the approximate pH of the lysosome. In certain embodiments, the hydrolyzable linker is a thioether linker (such as, e.g., a thioether attached to the therapeutic agent via an acylhydrazone bond (see, e.g., U.S. Pat. No. 5,622,929)). 
     In yet other embodiments, the linker is cleavable under reducing conditions (e.g., a disulfide linker). A variety of disulfide linkers are known in the art, including, for example, those that can be formed using SATA (N-succinimidyl-5-acetylthioacetate), SPDP (N-succinimidyl-3-(2-pyridyldithio)propionate), SPDB (N-succinimidyl-3-(2-pyridyldithio)butyrate) and SMPT (N-succinimidyl-oxycarbonyl-alpha-methyl-alpha-(2-pyridyl-dithio)toluene)-, SPDB and SMPT (See, e.g., Thorpe et al., 1987, Cancer Res. 47:5924-5931; Wawrzynczak et al., In Immunoconjugates: Antibody Conjugates in Radioimagery and Therapy of Cancer (C. W. Vogel ed., Oxford U. Press, 1987. See also U.S. Pat. No. 4,880,935.) 
     In yet other specific embodiments, the linker is a malonate linker (Johnson et al., 1995, Anticancer Res. 15:1387-93), a maleimidobenzoyl linker (Lau et al., 1995, Bioorg-Med-Chem. 3(10):1299-1304), or a 3′-N-amide analog (Lau et al., 1995, Bioorg-Med-Chem. 3(10): 1305-12). 
     Typically, the linker is not substantially sensitive to the extracellular environment. As used herein, “not substantially sensitive to the extracellular environment,” in the context of a linker, means that no more than about 20%, typically no more than about 15%, more typically no more than about 10%, and even more typically no more than about 5%, no more than about 3%, or no more than about 1% of the linkers, in a sample of ADC or ADC derivative, are cleaved when the ADC or ADC derivative present in an extracellular environment (e.g., in plasma). Whether a linker is not substantially sensitive to the extracellular environment can be determined, for example, by incubating independently with plasma both (a) the ADC or ADC derivative (the “ADC sample”) and (b) an equal molar amount of unconjugated antibody or therapeutic agent (the “control sample”) for a predetermined time period (e.g., 2, 4, 8, 16, or 24 hours) and then comparing the amount of unconjugated antibody or therapeutic agent present in the ADC sample with that present in control sample, as measured, for example, by high performance liquid chromatography. 
     In other, non-mutually exclusive embodiments, the linker promotes cellular internalization. In certain embodiments, the linker promotes cellular internalization when conjugated to the therapeutic agent (i.e., in the milieu of the linker-therapeutic agent moiety of the ADC or ADC derivate as described herein). In yet other embodiments, the linker promotes cellular internalization when conjugated to both the therapeutic agent and the antigen binding protein or antibody or derivative thereof (i.e., in the milieu of the ADC or ADC derivative as described herein). 
     A variety of linkers that can be used with the present compositions and methods are described in WO 2004010957 entitled “Drug Conjugates and Their Use for Treating Cancer, An Autoimmune Disease or an Infectious Disease” filed Jul. 31, 2003, and U.S. Provisional Application No. 60/400,403, entitled “Drug Conjugates and their use for treating cancer, an autoimmune disease or an infectious disease”, filed Jul. 31, 2002 (the disclosure of which is incorporated by reference herein). 
     Alternatively, a fusion protein comprising the antigen binding protein and cytotoxic agent may be made, e.g., by recombinant techniques or peptide synthesis. The length of DNA may comprise respective regions encoding the two portions of the conjugate either adjacent one another or separated by a region encoding a linker peptide which does not destroy the desired properties of the conjugate. 
     In yet another embodiment, the antibody may be conjugated to a “receptor” (such as streptavidin) for utilization in tumor pre-targeting wherein the antibody-receptor conjugate is administered to the patient, followed by removal of unbound conjugate from the circulation using a clearing agent and then administration of a “ligand” (e.g., avidin) which is conjugated to a cytotoxic agent (e.g., a radionucleotide). 
     The term “Non Human antibody or antibody fragment thereof” as used herein is meant to refer to antibodies or fragments thereof which originate from any species other than human wherein human includes chimeric antibodies. 
     The term “donor antibody” refers to an antibody (monoclonal, and/or recombinant) which contributes the amino acid sequences of its variable domains, CDRs, or other functional fragments or analogs thereof to a first immunoglobulin partner, so as to provide the altered immunoglobulin coding region and resulting expressed altered antibody with the antigenic specificity and neutralizing activity characteristic of the donor antibody. 
     The term “acceptor antibody” refers to an antibody (monoclonal and/or recombinant) heterologous to the donor antibody, which contributes all (or any portion, but preferably all) of the amino acid sequences encoding its heavy and/or light chain framework regions and/or its heavy and/or light chain constant regions to the first immunoglobulin partner. The human antibody is the acceptor antibody. 
     The term “Human acceptor sequence” as used herein is meant to refer to a framework of an antibody or antibody fragment thereof comprising the amino acid sequence of a VH or VL framework derived from a human antibody or antibody fragment thereof or a human consensus sequence framework into which CDR&#39;s from a non-human species may be incorporated. 
     The term “incorporation” of CDR&#39;s or hypervariable regions as used herein encompasses any means by which the non-human CDR&#39;s are situated with the human acceptor framework. It will be appreciated that this can be achieved in various ways, for example, nucleic acids encoding the desired amino acid sequence can be generated by mutating nucleic acids encoding the non-human variable domain sequence so that the framework residues thereof are changed to human acceptor framework residues, or by mutating nucleic acid encoding the human variable domain sequence so that the CDR&#39;s are changed to non-human residues, or by synthesizing nucleic acids encoding the desired sequence. In one embodiment the final sequence is generated in silico. 
     The present invention is now described by way of example only. The appended claims may include a generalisation of one of more of the following examples. 
     EXAMPLES 
     Example 1 Monoclonal Antibody Generation and Selection 
     1.1 Immunisation Strategies 
     The anti human BCMA mAb murine parental CA8 was identified from hybridomas derived from mice immunized with full length human BCMA. A BALB/c mouse was immunized i.p. with 25 μg of recombinant (rBCMA) protein combined with CFA. The mouse was boosted three times at one-month intervals with 25 μg of full length rBCMA protein+10 μg monophosphoryl lipid A-stable emulsion (MPL-SE) (Corixa Corporation, Seattle, Wash.) and given a pre-fusion boost of 30 μg rBCMA protein i.v. 3 days prior to fusion. Hybridomas were either generated and cloned using the ClonaCell-HY hybridoma cloning kit (StemCell Technologies, Vancouver, BC) or using a conventional method. In the conventional method, B cells from the spleens of the immunized animals were fused with Sp2/0 myeloma cells in the presence of PEG (Sigma-Aldrich, St. Louis, Mo.). After overnight recovery, fused cells were plated at limiting dilution in 96-well plates and subjected to hypoxanthine-aminopterin-thymidine selection. Hybridoma culture supernatants were examined for the presence of anti-BCMA antibodies by ELISA and flow cytometry 
     The anti human BCMA mAb murine parental S307118G03 was identified from hybridomas derived from SJL mice immunized with recombinant human BCMA/TNFRSF17-Fc chimera (R&amp;D 193-Fc) using the RIMMS method (Rapid immunisation multiple sites). At Day 0, 5 ug protein per mouse was emulsified in AS02a adjuvant at 2 sites on back (over haunches and over shoulders) and subjacent to the major lymph nodes at 4 sites on front.

The fusion was plated out into omnitrays containing semi solid medium prior to picking into 10×96 well plates and was screened directly from these 5 days later. 
     The anti human BCMA murine parental mAbs S332121F02 and S332126E04 were identified from hybridomas derived from SJL mice immunized with recombinant Fc fusion of the extracellular domain of human BCMA (4-53) BCMA using the RIMMS method (Rapid immunisation). At Day 0, 5 ug protein per mouse was emulsified in AS02a adjuvant at 2 sites on back (over haunches and over shoulders) and subjacent to the major lymph nodes at 4 sites on front. On day 6 5 ug recombinant cyno BCMA-Fc protein per mouse in RIBI adjuvant was injected subjacent to the major lymph nodes at 4 sites on front. On day 11 2.5 ug recombinant human BCMA-Fc and 2.5 ug recombinant cyno BCMA-Fc per mouse in RIBI adjuvant was injected subjacent to the major lymph nodes at 4 sites on front. On day 14 the animals were sacrificed and cells treated as for S307118G03. 
     The anti human BCMA murine parental mAb S322110D07 was identified from hybridomas derived from SJL mice immunised with recombinant Fc fusion of the extracellular domain of human BCMA (4-53) in complex with recombinant human April (R&amp;D 5860-AP/CF) premixed at 1:1 molar ratio. The mice were immunized i.p. with 5 ug April/Cyno BCMA-Fc complex in PBS, suspended in RIBI adjuvant, 100 ul dose per mouse and boosted 3 times at 3-4 week intervals with 2.5 ug April/Cyno BCMA-Fc complex in PBS, suspended in RIBI adjuvant, 100 ul dose per mouse injected via intraperitoneal route and given a pre-fusion boost of the same immunogen 1 day prior to fusion and treated as for 5307118G03. 
     The anti human BCMA mAb murine parental S335115G01 and 5335122F05 were identified from hybridomas derived from SJL mice immunized with a mixture of recombinant Fc fusion of the extracellular domain of human BCMA (4-53) and recombinant Fc fusion of the extracellular domain of cyno BCMA (4-52) using the RIMMS method (Rapid immunisation multiple sites). At Day 0, 2, 5 ug of each protein per mouse was emulsified in AS02a adjuvant and injected at 2 sites on the back (over haunches and over shoulders) and subjacent to the major lymph nodes at 4 sites on front. On day 6 and day 11 2.5 ug of each protein per mouse in RIBI adjuvant was injected subjacent to the major lymph nodes at 4 sites on front. On day 14 the animals were sacrificed. The lymph nodes and spleen were excised, disrupted and a Cytopulse electrofusion was performed using a 1:1 ratio with mouse myeloma cells X63 AG8 653.GFP.Bc1-2.11 (BioCat 112754; R17209/58). The fusion was plated out into omnitrays containing semi solid medium prior to picking into 32×96 well plates and was screened directly from these 5 days later. 
     Example 2 Humanisation 
     2.1 Cloning of CA8 Hybridoma Variable Regions 
     Total RNA was extracted from CA8 hybridoma cells, heavy and light variable domain cDNA sequence was then generated by reverse transcription and polymerase chain reaction (RT-PCR). The forward primer for RT-PCR was a mixture of degenerate primers specific for murine immunoglobulin gene leader-sequences and the reverse primer was specific for the antibody constant regions. Reverse primers specific for IgG1, IgG2a and IgG2b were used in this case as the isotype was unknown. To design the primers, DNA multiple sequence alignments of the leader sequences of the mouse V H  and V k  genes were generated. 
     2.2 Cloning of Chimeric CA8 
     The DNA expression constructs encoding the chimeric antibody were prepared de novo by build-up of overlapping oligonucleotides including restriction sites for cloning into mammalian expression vectors as well as a human signal sequence. HindIII and SpeI restriction sites were introduced to frame the VH domain containing the signal sequence for cloning into mammalian expression vectors containing the human yl constant region. HindIII and BsiWI restriction sites were introduced to frame the VL domain containing the signal sequence for cloning into mammalian expression vector containing the human kappa constant region. 
     2.3 Cloning of the Humanised CA8 Variants 
     The DNA expression constructs encoding the humanised antibody variants were prepared de novo by build-up of overlapping oligonucleotides including restriction sites for cloning into mammalian expression vectors as well as a human signal sequence. HindIII and SpeI restriction sites were introduced to frame the VH domain containing the signal sequence for cloning into mammalian expression vectors containing the human γ1 constant region. HindIII and BsiWI restriction sites were introduced to frame the VL domain containing the signal sequence for cloning into mammalian expression vector containing the human kappa constant region. 
     2.4 Expression of the Recombinant CA8 Antibodies (Including Antibody Quantification) 
     Expression plasmids encoding the heavy and light chains respectively were transiently co-transfected into HEK 293 6E cells and expressed at small scale to produce antibody. Antibodies were quantified by ELISA. ELISA plates were coated with anti human IgG (Sigma 13382) at 1 mg/ml and blocked with blocking solution (4% BSA in Tris buffered saline). Various dilutions of the tissue culture supernatants were added and the plate was incubated for 1 hour at room temperature. Dilutions of a known standard antibody were also added to the plate. The plate was washed in TBST and binding was detected by the addition of a peroxidise labelled anti human kappa light chain antibody (Sigma A7164) at a dilution of 1/1000 in blocking solution. The plate was incubated for 1 hour at room temp before washing in TBST. The plate was developed by addition of OPD substrate (Sigma P9187) and colour development stopped by addition of 2M H2SO4. Absorbance was measured at 490 nm and a standard curve plotted using data for the known standard dilutions. The standard curve was used to estimate the concentration of antibody in the tissue culture supernatants. Larger scale antibody preparations were purified using protein A and concentrations were measured using a Nanodrop (Thermo Scientific).

     2.5 Defucosylated Antibody Production 
     To generate defucosylated antibodies the heavy and light chains respectively were co-transfected into CHO DG44 MS705 BioWa cells and expressed at scale to produce antibody. Briefly, 30 μg DNA was linearised overnight with Not1, the DNA was ethanol precipitated and re-dissolved in TE buffer. From culture, 2.4×107 BioWa DG44 cells were obtained and washed in 14 ml of warmed PBS-sucrose. The cells were spun and the pellet resuspended in 1.6 ml of PBS-sucrose. Half (0.8 ml) of aforementioned cells, suspended in PBS-sucrose, were added to a BioRad cuvette with the 30 μg of linearised DNA (in 50 μl TE buffer). A BioRad GenePulser was programmed to 380V with a capacitance of 25 μF and the cuvette was entered for electroporation. The resulting 850 ul of electroporated cells and DNA were added to (80 ml) warmed SFM512 medium (including phenol red, 2XHT (nucleosides), glutamax and Gibco supplement4). Finally, the resulting 80 ml of cell suspension was transferred□ (150 μl/well) to each well of one of 4×96-well plates. After 48 hours, the medium was changed to nucleoside free by removing approximately 130 μl of conditioned and replacing with 150 μl of fresh selection medium SFM512 medium (including phenol red and glutamax). Every 3-4 days, 130-150 μl of conditioned medium was removed and replaced with fresh, selection medium. Wells were monitored for colour change and assayed for IgG concentration as discussed previously. 
     2.6 Additional Antibodies—Cloning of Hybridoma Variable Regions 
     Total RNA was extracted from 5307118G03, 5332121F02, S332126E04, 5322110D07, 5336105A07, 5335115G01 and 5335122F05 hybridoma cells. Heavy and light variable domain cDNA sequence was then generated by reverse transcription and polymerase chain reaction (RT-PCR). The forward primer for RT-PCR was a mixture of degenerate primers specific for murine immunoglobulin gene leader-sequences and the reverse primer was specific for the antibody constant regions, in this case isotype IgG2a. Primers were designed based on a strategy described by Jones and Bendig (Bio/Technology 9:88, 1991). RT-PCR was carried out for both V-region sequences to enable subsequent verification of the correct V-region sequences. DNA sequence data was obtained for the V-region products generated by the RT-PCR. 
     2.7 Additional Antibodies—Cloning of the Chimeras 
     The DNA expression constructs encoding the chimeric antibodies were prepared de novo by infusion advantage PCR cloning (Clonetech) of the V-gene PCR products into mammalian expression vectors. This cloning method enabled fusion the murine variable regions to human IgG1 H chain and kappa L chain constant regions. 
     2.8 S307118G03— Cloning of the Humanized Variants 
     Cloning was carried out as for paragraph 2.3. 
     2.9 S307118G03 Expression of the Recombinant Antibodies 
     Expression plasmids encoding the relevant heavy and light chains (listed in Table 8 below) were transiently co-transfected into HEK 293 6E cells and expressed at small scale to produce antibody. The antibodies were Protein A purified from the supernatants and quantified using the Nanodrop spectrophotometer.

     Gammabind Plus Protein G Sepharose (GE Healthcare) resin slurry (75 uL) was added to a each well of a deep well (2 mL capacity) filter plate. The antibodies to be conjugated were grouped by species and isotype and up to 0.5 mg of each antibody transferred to each well of the plate. Each antibody was transferred to two separate wells to facilitate the preparation of two conjugates, with the drug-linkers SGD-1006 and SGD-1269. The filter plate was then shaken at 1200 RPM for 2 hours at 5° C. to bind the antibodies to the resin. The filter plate was then centrifuged at 500×g for 3 minutes to ensure complete pulldown of all fluids and resin to the bottom of the each well. 
     The bound antibodies were then reduced by adding 500 uL of 10 mM TCEP in 100 mM KPO4, 150 mM NaCl, pH 7, 1 mM EDTA and shaking for 30 minutes at 22° C. Following reduction, the plate was again centrifuged to remove the TCEP solution and subsequently washed with PBS+1 mM EDTA, 1 mL per well. The wash solution was removed by centrifugation and the process repeated 3 times for a total of 4 washes. The bound and reduced antibodies were then conjugated using a mixture of NEM and drug linker prepared in accordance with the mole fractions indicated in Table 2.

     Separate mixtures of NEM and drug linker were thus prepared for each antibody species/isotype using 10 mM DMSO stock solutions of SGD-1006, SGD-1269 (See Table B) and NEM. When mixed at the appropriate ratio the total maleimide concentration was therefore still 10 mM, and this value was used to calculate the volume of maleimide solution to be added to each well. For example for a murine IgG1 with 5 reducible disulfides (10 available thiols when reduced) 0.5 mg of antibody at 150 kD is 3.33 nmol corresponding to 33.3 nmol of thiol. A 3-fold excess is therefore 100 nmol of total maleimide or 10 μl of the 10 mM drug linker/NEM mix. For the SGD-1269 conjugate this mix would then be prepared with 5.86 μL of SGD-1269 and 4.14 μL of NEM. The maleimide mix would then be diluted into 500 μL of PBS prior to addition to the immobilized reduced antibody. In practice, since multiple antibodies of each isotype were conjugated simultaneously a single SGD-1269/NEM mixed solution for each isotype was prepared by multiplying the number of wells containing that isotype by 104 per well then diluting into a volume of PBS equal to 500 μL times the number of wells. In like fashion a total of eight drug-linker/NEM mixes were prepared—four with SGD-1006 and four with SGD-1269—and diluted into PBS. These mixes were then added to the reduced antibodies (5004 per well) and the plate was shaken for 30 minutes at 22° C. The plate was then centrifuged as above to remove the excess reaction solution, and subsequently washed 4 times with PBS as before. 
     The bound ADCs were then eluted by adding 200 uL of 50 mM glycine pH 2.5 to each well and shaking the plate for 3 minutes at 1200 RPM. While shaking 20 uL of neutralization buffer (1M potassium phosphate, pH 7.4, 500 mM NaCl, 0.2% Tween-20) was added to each well of a 1 mL collection plate. The ADCs were then eluted into the collection plate by spinning at 1500×g for 6 minutes. The collection plate was then shaken briefly to ensure complete mixing of the neutralization buffer. 
     The concentration of each ADC was then determined with an absorbance plate reader by transferring the solutions into a UV assay plate (Costar model 3635, Corning) and measuring the optical density at 280 nm. An average IgG extinction coefficient of 1.45 mL mg-1 cm-1 was used to provide an adequate estimation of ADC concentration across the panel. To confirm successful conjugation, a reversed phase protein HPLC method (described below) was used to estimate the drug loading of the isotype controls. For the plate containing the humanization variants of CA8 this method was used to estimate the loading of all ADCs directly. 
     The reversed phase protein chromatography method for determining drug loading employs the PLRP-S polymeric stationary phase (Agilent Technologies). Since the antibodies were fully reduced during the conjugation process all of the antibody subunits elute from the column as single polypeptide chains allowing the subpopulations of light and heavy chain species with varying levels of drug loading to be evaluated separately. Thus, the analysis of these data allow for the calculation of the average light chain drug loading and the average heavy chain drug loading as independent factors which can then be combined to determine average antibody drug loading with the basic knowledge that each antibody is comprised of two light and two heavy chains. The chromatographic conditions were as follows: A PRLP-S column, 1000 Å, 50×2.1 mm, 8 um particle size (Agilent Technologies) with water+0.05% TFA as mobile phase A and acetonitrile+0.01% TFA as mobile phase B; elution with a linear gradient of 27% B to 42% B in 12.5 minutes. 
     Anti-BCMA antibodies were conjugated with SGD-1006 and SGD-1269 in three separate batches over a period of seven months. In the first batch a total of 29 antibodies were conjugated (resulting in 58 ADCs). The drug loading of each isotype control determined by PLRP chromatography and the data are summarized in Table 3.

     Mean drug loading and % CV are indicated for each isotype series at the bottom. An uncharacteristically large variability in drug loading was observed for the SGD-1269 ADCs prepared with mIgG2b antibodies; the reason for this is unclear. Also, the Fc-enhanced CA8 antibodies yielded somewhat lower drug loading levels than the other CA8 human variants; to address this, additional Fc-enhanced CA8 was conjugated in a solution-phase reaction to better match the drug loading achieved for the other antibodies. 
     Example 4—Binding Data 
     4.1 FMAT Binding Assay to Show Binding of Chimeric CA8 to Cells Expressing Human or Cyno BCMA. 
     Cryopreserved transfected human, cyno BCMA and mock transfected HEK293 cells were recovered from LN2 storage. Assay wells were prepared with human chimeric CA8 antibody, at a range of different concentrations, mixed with human BCMA HEK293, cyno BCMA HEK293 and mock transfected cells respectively. Anti-human IgG FMAT Blue secondary conjugate was added for detection of human chimeric CA8. The assay plates were left for a minimum of 90 minutes before the result was read on the ABI8200 (FMAT) plate reader. This showed that the CA8 antibody in chimeric form binds well to both human and cyno BCMA proteins expressed on HEK293 cells. 
     Results are shown in  FIG.  1   . 
     4.2 ELISA Experiment Showing Binding of Chimeric CA8 to Recombinant BCMA Protein 
     Chimeric CA8 antibodies were tested for binding to human BCMA and cyno BCMA expressed as Fc fusions. Human BCMA-Fc and cyno BCMA-Fc were coated to ELISA plates and the plates were blocked using BSA to reduce non specific binding. CA8 chimeric antibodies were added in a concentration range from 5 ug/ml to 0.1 ug/ml to the human and cyno BCMA coated ELISA plates. Any bound human chimeric CA8 antibody was detected using anti-human IgG HRP conjugated secondary antibody as appropriate. HRP substrate (TMB) was added to develop the ELISA. This showed that CA8 antibody binds to recombinant human and cyno BCMA in an ELISA assay. 
     Results are shown in  FIG.  2   . 
     4.3 Biacore Experiment to Show CA8 Antibody Binding to BCMA and TACI Proteins to Determine Cross Reactivity with TACI Protein. 
     CA8 chimera antibody was injected and captured on protein A. (A protein A derivitised sensorchip was used). Residual protein A binding was blocked with an injection of a high concentration of human IgG solution. BCMA-Fc, TACI-Fc or BAFF-R-Fc solutions were then tested for binding to the antibody. The 3 proteins were injected in sequence and binding events were measured. The surface was regenerated between injection of each protein. 
     Sensorgrams were analysed in the Biaevaluation program. Double reference subtraction was done to remove instrument noise and any non-specific binding from the sensorgram curves. This showed that CA8 was specific for binding to BCMA binding and not to TACI and BAFFR. 
     Binding of the CA8 antibody to BCMA-Fc, TACI-Fc and BAFF-R-Fc was plotted out as shown in  FIG.  3   . 
     4.4 Cell Binding and Neutralisation Data 
     4.4.1 Binding of Murine Anti BCMA Antibodies to Multiple Myeloma Cells and BCMA Expressing Cells 
     Multiple myeloma cell line H929 and ARH77-hBCMA 10B5 BCMA expressing transfectant cells were stained with murine S332211D07, S3332121F02 or S332126E04 or murine isotype control at 5 μg/mL. Multiple myeloma cell line H929 was stained with murine S307118G03. Cells were incubated for 20 mins at room temperature (RT) and then washed with FACS buffer (PBS+0.5% BSA+0.1% sodium azide) to remove unbound antibody. Cells were incubated with a secondary PE labelled anti-mouse IgG antibody for 15 minutes at RT and then washed with FACS buffer to remove unbound antibody. Cells were analysed by FACS to detect antibody bound to the cells. 
     The results ( FIG.  4   ) showed that all 4 murine antibodies bound to the H929 multiple myeloma cell line and the three antibodies tested on ARH77 BCMA transfected cells bound to these. 
     4.4.2 Binding Curve of Chimeric CA8 to Multiple Myeloma Cells as Determined by FACS 
     A panel of multiple myeloma cell lines were used to determine the binding of chimeric CA8. Cell lines H929, OPM-2, JJN-3 and U266 were stained with either chimeric CA8 or irrelevant antibody (Synagis) at varying concentrations for 20 minutes at RT. Cells were then washed with FACS buffer (PBS+0.5% BSA+0.1% sodium azide) to remove unbound antibody. Cells were incubated with a secondary PE labelled anti-human IgG antibody for 15 minutes at RT and then washed with FACS buffer to remove unbound antibody. Cells were analysed by FACS and mean fluorescence intensity (MFI) values measured to determine binding. 
     Results showed that chimeric CA8 bound to multiple myeloma cell lines H929, OPM-2, JJN-3 &amp; U266 in a dose dependent manner ( FIG.  5   ). 
     4.4.3 Binding of Humanised CA8 to BCMA Transfected Cells as Determined by FACS 
     ARH77-hBCMA 10B5 BCMA expressing transfectant cells or H929 cells were stained with either chimeric CA8 or humanised variants of CA8 designated J6M0, J6M1, J6M2, J9M0, J9M1, J9M2 at varying concentrations for 20 minutes at RT. Cells were then washed with FACS buffer (PBS+0.5% BSA+0.1% sodium azide) to remove unbound antibody. Cells were incubated with a secondary PE labelled anti-human IgG antibody for 15 minutes at RT and then washed with FACS buffer to remove unbound antibody. Cells were analysed by FACS and mean fluorescence intensity (MFI) values measured to determine binding. Results showed that chimeric CA8 and all antibodies tested apart from J9M2 bound to ARH77-hBCMA 10B5 BCMA expressing transfectant cells and H929 cells in a dose dependent manner ( FIG.  6   ). 
     4.5 Demonstration of Ability of CA8 and the Humanised Version J6M0 to Neutralise Binding of BAFF or APRIL to Recombinant BCMA. 
     The aim of this assay was to assess the ability of antibody CA8, and humanised version J6M0 in both wild type and afucosylated (Potelligent) form, at various concentrations, to neutralise the binding ability of either BCMA ligand, BAFF or APRIL. 
     96 well flat bottomed plates were coated overnight with 1 μg/mL solution of recombinant human BCMA Fc 4-53 in PBS. Following a wash step using 0.05% TWEEN20, plates were blocked with 2% Bovine Serum Albumin solution in PBS for 1 hour at room temperature. Plates were washed as before and 404 of each antibody (murine IgG, murine CA8, and chimeric CA8), starting at 10 μg/mL, titrated at 1 in 2 in duplicate was added to the relevant wells and incubated for 1 hour at room temperature. 40 μL of 2% BSA was added to the relevant control wells. 104 of either recombinant human BAFF (2149-BF/CF, R&amp;D Systems) or recombinant human APRIL (5860-AP/CF, R&amp;D Systems) was added at 30 ng/mL and 750 ng/mL respectively, giving a final concentration of 6 ng/mL and 150 ng/mL respectively in each well. Equivalent volume of 2% BSA was added to the relevant control wells. Plates were allowed to incubate for 2 hours at room temperature, after which they were washed as before. Biotinylated anti-human ligand (BAFF BAF124 or APRIL BAF884, R&amp;D Systems) was added to the relevant wells at 50 ng/mL and incubated for 1 hour. Following a wash step, 504 of a 1:4000 dilution of Streptavidin-HRP (Amersham RPN4401) was added to each well and incubated for 30 minutes at room temperature. The wash process was repeated again followed by the addition of 1004 of Tetramethylbenzidine substrate solution (T8665, Sigma) into each well. Plates were incubated for 20-25 minutes at room temperature, wrapped in foil. The reaction was stopped with the addition of 1004 of 1M H 2 SO 4 . Optical density was determined at 450 nm using Spectromax reader. See  FIG.  7 A  and B. 
     In a plate based assay for neutralisation of binding of BAFF or APRIL to BCMA, the EC50 values calculated for chimeric CA8 were 0.695 μg/mL and 0.773 μg/mL respectively. The values for the humanised J6M0 were 0.776 ng/ml and 0.630 ng/ml. The values for the J6M0 potelligent version were 0.748 and 0.616 ng/ml respectively. 
     4.6 Effect of Chimerized CA8 and Humanised J6M0 BCMA Antibody on BAFF or APRIL Induced Phosphorylation of NFkB in H929 Cells. 
     In one set of experiments, H-929 cells were plated at 75,000 cells/well in a 96 well plate in serum free medium. The chimeric CA8 antibody was added 24 hours later to give final well concentrations up to 200 ug/ml. Ten minutes later, BAFF or APRIL ligand were added to the cells to give final well concentrations of 0.6 or 0.3 ug/ml respectively. After 30 minutes the cells were lysed and phosphorylated NfkappaB levels measured using a MSD pNFkappaB assay. 
     The chimeric BCMA antibody CA8 neutralised both BAFF and APRIL induced NfkappaB cell signalling in H-929 cells. It was particularly potent at neutralising BAFF induced NfkappaB cell signalling in this cell type with a mean IC50 of 10 nM, compared to 257 nM for APRIL induced NfkappaB cell signalling. 
     Meaned Data for 2 Experiments 
     IC50s were 10 nM for BAFF induced NfkappaB neutralisation and 257 nM for APRIL induced NfkappaB neutralisation (mean of 2 independent experiments) are shown in Table 7.

     A further set of experiments were carried out to aim to understand why there was such a discrepancy between the potency in neutralisation of APRIL and BAFF in the cell based system. Following the discovery of the soluble form of BCMA the experimental design was changed to include a step where the H929 cells were washed prior to the assay to reduce the interference from the antibody binding to soluble BCMA. H-929 cells were washed 3 times to remove any sBCMA and resuspended in serum free medium. J6M0 potelligent antibody was added to a 96 well plate to give a final well concentrations up to 100 ug/ml along with BAFF or APRIL ligand to give a final well concentration of 0.6 or 0.2 ug/ml respectively. H-929 cells were then plated at 7.5×104 cells/well in serum free medium. 30 minutes later the cells were lysed and phosphorylated NFkappaB levels measured using a MSD pNFkappaB assay. This is data from one experiment. Each data point is the mean/sd of two replicates. The data from this experiment is shown in  FIG.  7   c   . The IC50s for inhibition of BAFF and APRIL signalling were determined as 0.91 ug/ml and 2.43 ug/ml respectively. 
     4.7 ProteOn Analysis of Anti-BCMA CA8 Chimeric and Humanised Constructs 
     The initial screen of CA8 chimeric and humanised variants was carried out on the ProteOn XPR36 (Biorad). The method was as follows; Protein A was immobilised on a GLC chip (Biorad, Cat No: 176-5011) by primary amine coupling, CA8 variants were then captured on this surface and recombinant human BCMA (in house or commercial US Biological, B0410) materials (run 2 only)) passed over at 256, 64, 16, 4, 1 nM with a 0 nM injection (i.e. buffer alone) used to double reference the binding curves, the buffer used is the HBS-EP buffer. 50 mM NaOH was used to regenerate the capture surface. The data was fitted to the 1:1 model using the analysis software inherent to the ProteOn XPR36. Run 1 corresponds to the first screen of humanised CA8 variants (JO to J5 series) and run 2 to the second screen of humanised CA8 variants (J5 to J9 series). Both runs were carried out at 25° C. 
     The data obtained from run1 are set out in Table 8 and data from run 2 are set in Table 9 Several molecules in the Run 2 (Table 09) failed to give affinity values measurable by ProteOn, this was due to the off-rate being beyond the sensitivity of the machine in this assay, this does however indicate that all these molecules bind tightly to recombinant human BCMA. From Run 1 the data indicates that some constructs did not show any binding to recombinant cyno BCMA.

     4.8 BIAcore Analysis of Anti-BCMA CA8 Chimeric and Humanised Constructs (J7 to J9 Series) 
     Protein A was immobilised on a CMS chip (GE Healthcare, Cat No: BR-1005-30) by primary amine coupling and this surface was then used to capture the antibody molecules. Recombinant human BCMA (US Biological, B0410) was used as analyte at 256 nM, 64 nM, 16 nM, 4 nM and 1 nM. Regeneration of the capture surface was carried out using 50 mM NaOH. All binding curves were double referenced with a buffer injection (i.e. 0 nM) and the data was fitted to the using the 1:1 model inherent to T100 evaluation software. The run was carried out at 37° C., using HBS-EP as the running buffer. 
     The results showed the molecules tested with the exception of J9M2 bind to recombinant human BCMA, with similar affinity as the chimeric molecule. Data generated from this experiment are presented in table 10.

     4.9 BIAcore Analysis of Anti-BCMA CA8 Chimeric and Humanised Constructs J6M0 and J9M0 
     Protein A was immobilised on a CMS chip (GE Healthcare, Cat No: BR-1005-30) by primary amine coupling and this surface was then used to capture the antibody molecules. Recombinant human BCMA (US Biological, B0410) was used as analyte at 256 nM, 64 nM, 16 nM, 4 nM and 1 nM. Regeneration of the capture surface was carried out using 50 mM NaOH. All binding curves were double referenced with a buffer injection (i.e. 0 nM) the data was fitted to the using the 1:1 model inherent to T100 evaluation software. The run was carried out at 25° C. and 37° C. for experiment 1 and only 37° C. for experiment 2 using HBS-EP as the running buffer. 
     The both runs identified J9M0 as the best molecule in term of overall affinity to human BCMA. Data generated from this experiment are presented in table 11.

     4.10. ProteOn Analysis of New Anti-BCMA Chimeric Constructs 
     The initial screen of the new chimeric variants from the second batch of hybridomas was carried out on the ProteOn XPR36 (Biorad). The method was as follows; Protein A was immobilised on a GLM chip (Biorad, Cat No: 176-5012) by primary amine coupling, anti-BCMA variants were then captured on this surface and recombinant human BCMA (in house material) passed over at 256, 64, 16, 4, 1 nM with a 0 nM injection (i.e. buffer alone) used to double reference the binding curves, the buffer used is the HBS-EP buffer. Regeneration of the capture surface was carried out using 50 mM NaOH. The data was fitted to the 1:1 model using the analysis software inherent to the ProteOn XPR36. The run was carried out at 25° C. Data generated from this experiment are presented in table 12.

     Example 5 Cell Killing Assays 
     5.1 ADCC Potencies of Chimeric CA8 and Defucosylated Chimeric CA8 Version in ARH77 Cells Expressing BCMA 
     Human natural killer (NK) cells were incubated with europium labelled ARH77 BCMA transfected target cells (10B5) in the presence of varying concentrations of antibody at an E:T ratio of 5:1 for 2 hours. Europium release from the target cells was measured and specific lysis calculated. 
     Result: Chimeric CA8 and defucosylated chimeric CA8 killed BCMA expressing target cells via ADCC. The defucosylated chimeric antibody showed more potent ADCC activity, as measured by a higher percent lysis achieved with all the target cells tested and a ten-fold lower EC 50  on the high BCMA expressing target cell line 10B5, compared to the parent chimeric antibody. See  FIGS.  8 A and  8 B . 
     5.2 ADCC Activity of CA8 Humanised Antibodies Using ARH77 BCMA Expressing Target Cells and PBMC as Effectors 
     Human PBMC were incubated with europium labelled ARH77 BCMA transfected target cells (10B5) in the presence of varying concentrations of humanised versions of CA8 antibody (5 ug/ml to 0.005 ug/ml) at an E:T ratio of 5:1 for 2 hours. Europium release from the target cells was measured and specific lysis calculated. 
     Result: 
     Result: All the J5, J6, J7 J8 &amp; J9 series of humanised variants of CA8 showed ADCC activity against the ARH77 high BCMA expressing cell line 10B5 in a dose dependent manner. ADCC was at a similar level as that found in the experiments using chimeric CA8 molecule. See  FIG.  9   . 
     5.3 ADCC Potencies of Chimeric 5322110F02, 5322110D07 and 5307118G03 and Humanised 5307118G03 H3L0 Against ARH77 10B5 Cells Expressing BCMA with Purified NK Cells as Effector Cells 
     Human natural killer (NK) target cells were incubated with europium labelled ARH77 BCMA transfected target cells (10B5) in the presence of varying concentrations of antibody at an E:T ratio of 5:1 for 2 hours. Europium release from the target cells was measured and specific lysis calculated. 
     Result: all 4 antibodies tested showed ADCC activity against ARH77 10B5 cells. See  FIG.  10   . 
     5.4 Antibody-Drug Conjugate (ADC) Activity of Chimeric CA8 ADCs. 
     Measuring ADC activity of chimeric CA8 antibody, chimeric CA8-mcMMAF antibody drug conjugates and chimeric CA8-vcMMAE antibody drug conjugates against human multiple myeloma cell lines. 
     Multiple Myeloma cell lines were treated with chimeric CA8 antibody-drug conjugates to determine the ADC concentrations required for growth inhibition and death. 
     The antibody drug conjugates tested were added to wells containing multiple myeloma cells at concentrations ranging from 1 ug/ml to 5 ng/ml. The plates were incubated at 37° C. for 96 hours at which point viable cells were quantitated using Cell titre Glo. The unconjugated chimeric CA8 antibody showed no significant growth inhibitory activity at the antibody concentrations that were tested. The chimeric CA8-mcMMAF antibody-drug conjugate showed greater growth inhibitory activity than the chimeric CA8-vcMMAE antibody-drug conjugate in all 4 of the multiple myeloma cell lines that were tested. See  FIG.  11    and Table 13

     5.5 Measuring Cell Cycle Arrest Activity of Chimeric CA8 Antibody, Chimeric CA8-mcMMAF Antibody Drug Conjugates and Chimeric CA8-vcMMAE Antibody Drug Conjugates Against Human Multiple Myeloma Cell Line H929. 
     To determine the mechanism that chimeric CA8 Antibody Drug Conjugates (ADC&#39;s) cause growth inhibition in multiple myeloma cells, the cell cycle of NCI-H929 cells was monitored by measuring cellular DNA content through fixed cell propidium iodide staining at multiple timepoints following chimeric CA8 antibody and chimeric CA8 ADC treatment. 
     At the chimeric CA8 ADC concentration tested (50 ng/mL), the chimeric CA8-mcMMAF ADC caused significant G2/M cell cycle arrest (4N DNA content) which peaked at 48 hours. At the later timepoints 48, 72 and 96 hours, treatment with the chimeric CA8-mcMMAF ADC resulted in accumulation of a cell population with sub-2N DNA content, which is representative of cell death. At the 50 ng/mL concentration tested the chimeric CA8-vcMMAE ADC had no significant effect on G2/M cell cycle arrest or sub-G1 accumulation. See  FIG.  12   . 
     5.6 Phospho-Histone-H3 (Thr11) Staining as a Marker for Chimeric CA8-mcMMAF Antibody Drug Conjugate and Chimeric CA8-vcMMAE Antibody Drug Conjugate Induced Mitotic Arrest. 
     To determine if the accumulation of cells with 4N DNA content is a specific result of mitotic arrest induced by the chimeric CA8 ADCs NCI-H929 cells were stained with an anti-phospho-Histone H3 antibody following treatment with increasing concentrations of unconjugated chimeric CA8, chimeric CA8-vcMMAE or chimeric CA8-mcMMAF for 48 hours. 
     Treatment with chimeric CA8 ADCs resulted in a dose-dependent accumulation of NCI-H929 cells that stained positive for 84eroxidi-Histone H3 (Thr11), a specific marker of mitotic cells. The chimeric CA8-mcMMAF ADC caused accumulation of 84eroxidi-Histone H3 positive cells at lower concentrations than the chimeric CA8-vcMMAE ADC. See  FIG.  13   . 
     5.7 Measuring Apoptosis in NCI-H929 Cells in Response to Chimeric CA8 ADCs by Staining for Annexin V. 
     To determine if the accumulation of cells with sub-2N DNA content is a specific result of apoptosis induced by the chimeric CA8 ADCs, NCI-H929 cells were stained with an anti-Annexin-V antibody following treatment with increasing concentrations of unconjugated chimeric CA8, chimeric CA8-vcMMAE or chimeric CA8-mcMMAF for 48 hours. Treatment with chimeric CA8 ADCs resulted in a dose-dependent accumulation of NCI-H929 cells that stained positive for Annexin-V, a specific marker of apoptosis. The chimeric CA8-mcMMAF ADC caused accumulation of Annexin-V positive cells at lower concentrations than the chimeric CA8-vcMMAE ADC. See  FIG.  14   . 
     5.8 Antibody-Drug Conjugate (ADC) Activity of Humanised Variants of CA8 Anti-BCMA Antibody-Drug Conjugates. 
     Cells were plated in 96-well plates (4,000 cells per well in 100 uL of RPMI+10% FBS) Naked antibody or ADC was added 6 hours after cell seeding and plates were incubated for 144 hours. Growth inhibition in the presence of the antibodies or ADCs was measured at 144 hours using Cell Titre glo. Data points represent the mean of triplicate CellTiterGlo measurements. Error bars represent standard error. 
     Multiple Myeloma cell lines NCI-H929 and OPM2 were treated with humanized CA8 anti-BCMA antibody-drug conjugates to determine the ADC concentrations required for growth inhibition and death. The mcMMAF and vcMMAE antibody-drug conjugate forms of these antibodies showed significant growth inhibitory activity comparable to that found with the CA8 chimera. Variant J6M0 showed higher potency than the chimera and data is shown in  FIG.  15    in H929 cells and OPM2 cells. The mcMMAF antibody-drug conjugate showed greater growth inhibitory activity than the vcMMAE antibody-drug conjugate for all antibodies in both cell lines tested. Results for all humanized variants are shown in Table 14.

     5.9 Antibody-Drug Conjugate (ADC) Activity of Other Murine Anti-BCMA Antibody-Drug Conjugates. 
     Cells were plated in 96-well plates (4,000 cells per well in 100 uL of RPMI+10% FBS) Antibody or ADC was added 6 hours after cell seeding and plates were incubated for 144 hours. Growth inhibition in the presence of the ADCs was measured at 144 hours using Cell Titre glo. The mean of triplicate CellTiterGlo measurements are shown. Table 15a and 15b are from experiments carried out at different times on different series of antibodies. Multiple Myeloma cell lines NCI-H929 and U266-B1 were used for antibodies in Table 15a. The mcMMAF and vcMMAE antibody-drug conjugate forms of murine antibodies S322110D07, S332121F02 and S332136E04 showed significant growth inhibitory activity. The mcMMAF antibody-drug conjugate showed greater growth inhibitory activity than the vcMMAE antibody-drug conjugate in all of the murine anti-BCMA antibodies tested where activity was seen. IC50 figures are shown in Table 15a. See  FIG.  16    for dose response curves for these three antibodies and also 5107118G03. Error bars represent standard error. NCI-H929, U266-B1, JJN3 and OPM2 cells for antibodies in Table 15b were treated with a different series of murine anti-BCMA antibody-drug conjugates to determine the ADC concentrations required for growth inhibition and death. IC50 figures are shown in Table 15b. All 5 antibodies shown on the table had significant ADC activity.

     5.10 ADCC Potency of Conjugated, Afucosylated J6M0 (Potelligent) 
     Afucosylated J6M0 conjugated to MMAE or MMAF was tested in ADCC assays using BCMA transfectants to ensure that its ADCC activity was not compromised by the conjugation. Europium labelled ARH77-10B5 cells were incubated with various J6M0 WT and Potelligent BCMA antibodies at concentrations up to 10000 ng/ml for 30 minutes prior to the addition of PBMCs (PBMC: target cell ratio 50:1). Two hours later an aliquot of cell media was sampled and mixed with enhancement solution. After 30 minutes on a plate shaker, europium release was monitored on the Victor 2 1420 multi-label reader. Datapoints represent means of triplicate values. This data is representative of 2 experiments. 
     There were no significant differences in ADCC potency between the unconjugated and ADC forms of J6M0 Potelligent. In the same experiment a wild type version of J6M0 was included to show how the potency compares to the afucosylated version. As expected, defucosylation resulted in a lower EC50 and higher maximal lysis. No lysis was observed with the Fc disabled form of J6M0. (FIG. 17) 
     5.11 ADCC Potency of Afucosylated J6M0 on MM Cell Lines 
     Human PBMC were incubated with multiple myeloma target cells at an E:T ratio of 50:1 in presence of varying concentrations of afucosylated (Potelligent) J6M0 The percentage of target cells remaining in the effector+target cell mixture after 18 hours was measured by FACS using a fluorescently labelled anti-CD138 antibody to detect the target cells and the percent lysis calculated. This is representative of several experiments. 
     J6M0 Potelligent antibody showed ADCC activity against all five multiple myeloma target cell lines tested. This was important to test since earlier studies were carried out using transfected cells. Results are shown in  FIG.  18   . Full dataset with multiple donors is shown in Table 16 The potencies were all in a similar range as those found with the transfectants. The ADCC activity was not directly related to BCMA surface expression on these cell lines.

     Example 6. Xenograft Data 
     6.1 Murine xenografts of human MM cell lines were tested to ensure that antibody potency detected in vitro can also be demonstrated in vivo. The cell line selected for xenograft studies was NCI-H929 which is sensitive to ADC and ADCC killing in vitro. Studies were carried out in immunocompromised CB.17 SCID mice which lack T and B cells but maintain NK cells to allow for ADCC activity. However it should be noted that although human IgG1 can engage murine Fc receptors, the Potelligent enhancement does not improve the affinity as it does with human Fc receptors. 
     6.2 Impact of Unconjugated and MMAE or MMAF Conjugated J6M0 on NCI-H929 Tumour Growth. 
     In order to independently analyze both the ADCC and ADC activities of J6M0 we tested J6M0 antibody in the presence and absence of MMAF or MMAE conjugation. By testing the unconjugated J6M0, any anti-tumour effects could be attributed to some combination of ADDC and functional inhibitory activity. 
     Mice with NCI-H929 tumours that had reached a volume of 200 mm 3  on average were treated with a human IgG1 control or the J6M0 antibody (unconjugated, MMAE or MMAF) twice weekly at a dose of 50 ug or 100 ug, for 2 weeks. Results from this study show that a 100 ug dose of the J6M0-MMAF conjugate resulted in elimination of tumours in those mice which have completed the dosing. The J6M0-MMAF mice were maintained for 40 days after the last dose with no recurrence of tumour occurring. These results from this experiment demonstrate that MMAF conjugation had increased anti-tumour activity over both unconjugated J6M0 antibody and J6M0-MMAE conjugate See  FIG.  19   . 
     Example 7 Evaluation of Soluble BCMA Levels from MM Patient Serum 
     7.1 It is currently unknown whether BCMA is present extracellularly and can be detected in the blood. In this work, we determined the serum level of human BCMA from MM patients. Serum samples from 54 MM and plasma cell dyscrasia patients and 20 normal control samples were analyzed by ELISA. Human Subject Approval was obtained from Western Institutional Review Board. 
     7.2 Assessment of Serum Human BCMA Levels 
     Blood, from patients and normal controls in the clinic, were collected in serum collection tubes. MM patient samples were from a variety of stages (progressive disease, remission, relapsed, newly diagnosed, and others). The Blood samples were spun at 10,000 rpm for 10 minutes and serum transferred into sterile micro-centrifuge plastic tubes. 
     A Human BCMA/TNFRSF17 ELISA kit from R&amp; D Systems (catalog # DY193E) which measures soluble human BCMA levels was used to detect BCMA following the standard protocol supplied with the kit. 
     Briefly, 96 well micro-plates were coated with 100 ul per well capture antibody and incubated overnight at 4° C. The plates were washed three times with wash buffer (0.05% Tween 20 in PBS, pH 7.2) and blocked with 300 ul of 1% BSA in PBS at room temperature for 2 hours. The plates were washed three times with washing buffer. 100 ul of serum sample or standard was added into each well and incubated for 2 hours at room temperature. The plates were washed three times with washing buffer and then 100 ul of the detection antibody was added to each well and incubated 2 hours at room temperature. 100 ul of Streptavidin-HRP was added in each well after washing plates three times and incubated in dark room for 20 minutes. The plates were washed three times and added 50 ul stop solution and then determined by micro-plate reader with 570 nM wavelength. 
     A series of assays were carried out in order to determine the serum dilution factor appropriate for the levels of BCMA which were present. A dilution factor of 1:500 was found to be suitable for the majority of samples and is the dilution factor used in the data shown in  FIG.  20   . The full data set is shown in Table 17. 
     Patient and normal control serum samples diluted and run in triplicates had BCMA levels determined. The serum levels of BCMA were significantly elevated in the sera from MM patients compared with normal controls in this study. When the disease subset was divided further there was a trend towards elevated serum levels of BCMA in the sera from progressing MM patients compared with those in remission. This is the first report identifying serum BCMA in any human disease and suggests that these levels may be a novel biomarker for monitoring disease status and therapeutic response of MM patients and for other patients with plasma cell mediated diseases.
