Antibody Quality and Performance Guarantee
A microtiter plate was coated overnight with various antigens at a concentration of 5μg/ml. After washing and blocking with PBST + 5% BSA, detection was performed using HRP conjugated Human anti-belimumab antibody, clone AbD60138ia (HCA429) at a concentration of 2μg/ml in HISPEC assay diluent (BUF049A) followed by QuantaBlu fluorogenic peroxidase substrate. HRP conjugation of the antibody used in this assay was performed using a LYNX Rapid HRP Antibody Conjugation Kit (LNK002P).
A microtiter plate was coated overnight with belimumab, human IgG1 kappa control, human IgG1 lambda control at a concentration of 5μg/ml or 10% human normal serum (NHS). After washing and blocking with PBST + 5% BSA, detection was performed using HRP conjugated Human anti belimumab antibody, clone AbD60138ia (HCA429) titrated to the given concentrations in HISPEC assay diluent (BUF049A) followed by QuantaBlu fluorogenic peroxidase substrate.
Data for belimumab is shown as the mean of three measurements. HRP conjugation of the antibody used in this assay was performed using a LYNX Rapid HRP Antibody Conjugation Kit (LNK002P).
A microtiter plate was coated overnight with BAFF at a concentration of 1μg/mL. After washing and blocking with PBST + 5% BSA, a pre-incubated mixture of biotin conjugated belimumab (0.15μg/mL) plus increasing concentrations of Human anti belimumab antibody, clone AbD60138ia (HCA429) in the monovalent Fab format was added. Free biotin conjugated belimumab, still capable of binding to the BAFF coated plate, was detected using HRP conjugated neutravidin followed by QuantaBlu fluorogenic peroxidase substrate. The non-inhibitory Human anti belimumab antibody, clone AbD59897ad (TZA0102) was used as a negative control.
Data is shown as the mean of three measurements.
A microtiter plate was coated overnight with belimumab at a concentration of 1μg/ml. After washing and blocking with PBST + 5% BSA, PBST with 10% human serum was added spiked with increasing concentrations of Human anti belimumab antibody, clone AbD60138ia (HCA429, blue), clone AbD60136ia (HCA430, red), and clone AbD60132ia (HCA431, black). Detection was performed using biotin conjugated belimumab followed by HRP conjugated neutravidin and QuantaBlu fluorogenic peroxidase substrate.
Data is shown as the mean of three measurements.
Filter by Application:
E Reset| Human Anti-Belimumab Antibody, clone AbD60138ia is a paratope specific, inhibitory, anti-idiotypic antibody (Type 1) that specifically recognizes the free human monoclonal antibody drug belimumab, and its biosimilar products. It does not recognize the drug target, the B-cell activating factor BAFF (CD257), nor belimumab in complex with BAFF. HCA429 is a fully human recombinant monoclonal antibody with IgG1 isotype and is suitable as a surrogate positive control or calibrator in an anti-drug antibody (ADA) assay. This antibody has a monovalent intrinsic affinity of 16nM for belimumab and is one of the three antibodies offered for ADA assays. Antibody HCA430 has an affinity of 3nM and HCA431 has an affinity of 0.2nM for belimumab. Belimumab (trade name Benlysta) is a fully human monoclonal antibody of the IgG1/lambda isotype that binds to the B-cell activating factor BAFF to prevent its binding to B cells. Although part of the normal immune system, B cells are also responsible for the over-aggressive immune response observed in autoimmune diseases, such as systemic lupus erythematosus (SLE). Through its binding to BAFF, belimumab makes BAFF unavailable to B cells, which induces B cells apoptosis and therefore, a reduction in the overall number of circulating B cells. Therefore, belimumab acts as an immunosuppressant drug and is approved for the treatment of systemic lupus erythematosus. View a summary of all anti-belimumab antibodies |
