Ipilimumab antibody | AbD34428ia
A microtiter plate was coated overnight with various antigens at a concentration of 5 μg/ml. After washing and blocking with PBST + 5% milk, detection was performed using HRP conjugated Human Anti-Ipilimumab Antibody, clone AbD34428ia (HCA328) at a concentration of 2 μg/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 ipilimumab, human IgG1 kappa, human IgG1 lambda or hCTLA-4 at a concentration of 5 µg/ml. After washing and blocking with PBST + 5% BSA, detection was performed using HRP conjugated Human Anti-Ipilimumab Antibody, clone AbD34428ia (HCA328) titrated to the given concentrations in HISPEC Assay Diluent (BUF049A) followed by QuantaBlu Fluorogenic Peroxidase Substrate. Data for ipilimumab are 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 recombinant human CTLA-4 at a concentration of 1 µg/ml. After washing and blocking with PBST + 5% BSA, a pre-incubated mixture of HRP conjugated ipilimumab (0.3 µg/ml) plus increasing concentrations of Human Anti-Ipilimumab Antibody, clone AbD34428 (HCA328) in the monovalent Fab format was added. Free HRP conjugated ipilimumab, still capable of binding to the human CTLA-4 coated plate, was detected using QuantaBlu Fluorogenic Peroxidase Substrate. Data are shown as the mean of three measurements.
A microtiter plate was coated overnight with ipilimumab at a concentration of 1 µg/ml. After washing and blocking with PBST + 5% BSA, PBST with 10% human serum was added spiked with increasing concentrations of Human Anti-Ipilimumab Antibody, clone AbD34283ia (HCA327, black), clone AbD34428ia (HCA328, red) or clone AbD34429ia (HCA329, blue). Detection was performed using HRP conjugated ipilimumab followed by QuantaBlu Fluorogenic Peroxidase Substrate. Data are 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).

Antibody Quality and Performance Guarantee
| Human Anti-Ipilimumab Antibody, clone AbD34428ia is a paratope specific, inhibitory anti-idiotypic antibody that specifically recognizes the monoclonal antibody ipilimumab. It does not recognize free human CTLA-4 (cytotoxic T-lymphocyte antigen-4) or ipilimumab in complex with CTLA-4. Clone AbD34428ia is a fully human recombinant monoclonal antibody with IgG1 isotype and is suitable as a surrogate positive control or or reference standard in an anti-drug antibody (ADA) assay. This antibody has a monovalent intrinsic affinity of 0.3 nM, and is one of three antibodies with different affinities offered for ADA assays. Antibody HCA327 has affinity 16 nM and HCA329 has affinity 1 nM. Ipilimumab (Yervoy) is a human IgG1/kappa antibody developed from a transgenic mouse. It has been approved by the FDA for the treatment of metastatic melanoma, renal cell carcinoma, and in combination with nivolumab for the treatment of previously treated microsatellite instability-high/deficient mismatch repair (MSI-H/dMMR) metastatic colorectal cancer. Ipilimumab activates the immune system by targeting CTLA-4, a protein receptor that downregulates the immune system. The action of cytotoxic T lymphocytes (CTLs) to recognize and destroy cancer cells is subject to an inhibitory mechanism that interrupts this destruction. Ipilimumab turns off this inhibitory mechanism and allows CTLs to function. View a summary of all anti-ipilimumab antibodies |
