Avelumab antibody | AbD40526ia
A microtiter plate was coated overnight with various antigens at a concentration of 5 μg/ml. After washing and blocking with PBST + 5% BSA, detection was performed using HRP conjugated Human Anti-Avelumab Antibody, clone AbD40526ia (HCA398) 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 avelumab, recombinant His-tagged human PD-L1, adalimumab, human IgG1 kappa control and human IgG1 lambda control at a concentration of 5 µg/ml. After washing and blocking with PBST + 5% BSA, detection was performed using HRP conjugated Human Anti-Avelumab Antibody, clone AbD40526ia (HCA398) titrated to the given concentrations in HISPEC Assay Diluent (BUF049A) 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).
A microtiter plate was coated overnight with recombinant His-tagged human PD-L1 at a concentration of 1 µg/ml. After washing and blocking with PBST + 5% BSA, a pre-incubated mixture of avelumab (0.15 µg/ml) plus increasing concentrations of Human Anti-Avelumab Antibody, clone AbD40526ia (HCA398) or Type 3 clone AbD42040ad (TZA042), both in the monovalent Fab format, were added. Free avelumab, still capable of binding to the human PD-L1 coated plate, was detected using HRP conjugated Mouse Anti-Human IgG (Fc) CH2 Domain Antibody (MCA647P) followed by QuantaBlu Fluorogenic Peroxidase Substrate. Data are shown as the mean of three measurements.
A microtiter plate was coated overnight with avelumab 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-Avelumab Antibody, clone AbD40519ia (HCA396, black), clone AbD40525ia (HCA397, blue) or clone AbD40526ia (HCA398, red). Detection was performed using HRP conjugated avelumab 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). Data are shown as the mean of three measurements.

Antibody Quality and Performance Guarantee
| Human Anti-Avelumab Antibody, clone AbD40526ia is a paratope specific, inhibitory anti-idiotypic antibody (Type 1) that specifically recognizes the free human monoclonal antibody drug avelumab. The antibody does not recognize free PD-L1 nor avelumab in complex with PD-L1. This antibody can be used to measure free avelumab levels in serum from patients. This antibody is available as a full length IgG1 antibody (HCA398) for use in ADA assays. Avelumab (Bavencio) is a human IgG1/lambda antibody with allotype IGHG1*05 (G1m17,1). It binds to programmed death-ligand 1 (PD-L1, CD274) on tumor cells, blocking its interaction with PD-1 and B7-1 receptors on T-lymphocytes. PD-L1 is an immune checkpoint protein expressed on tumor cells and tumor-infiltrating immune cells that down regulates T-cell function, so by blocking these receptors anti-tumor T-cell activity can be restored. In vitro, the drug has been shown to stimulate natural killer cell-mediated direct tumor cell lysis by inducing antibody-dependent cell-mediated cytotoxicity. Avelumab has been approved both as monotherapy for the treatment of adult patients with metastatic Merkel cell carcinoma (MCC) and for the treatment of advanced Renal Cell Carcinoma (RCC). |
