Pembrolizumab antibody | AbD30689
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 Human Anti-Pembrolizumab Antibody, clone AbD30689 (HCA296) at a concentration of 2 μg/ml and an HRP labeled anti-DYKDDDDK tag antibody in HISPEC Assay Diluent (BUF049A) followed by QuantaBlu Fluorogenic Peroxidase Substrate.
A microtiter plate was coated overnight with pembrolizumab or human IgG4-Pro, human PD-1, nivolumab, natalizumab or trastuzumab at a concentration of 5 µg/ml. After washing and blocking with PBST+5% BSA, detection was performed using Human Anti-Pembrolizumab Antibody, clone AbD30689 (HCA296) titrated to the given concentrations in PBST, followed by detection with an HRP labeled anti-DYKDDDDK tag antibody in HISPEC Assay Diluent (BUF049A) and QuantaBlu Fluorogenic Peroxidase Substrate. Data are shown as the mean of three measurements.
A microtiter plate was coated overnight with Human Anti-Pembrolizumab Antibody, clone AbD30689 (HCA296) at a concentration of 1 µg/ml. After washing and blocking with PBST+5% BSA, 10% human serum was added spiked with increasing concentrations of pembrolizumab. Detection was performed using HRP conjugated Human Anti-Pembrolizumab Antibody (HCA297) at a concentration of 2 µg/ml in HISPEC Assay Diluent (BUF049A) and 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 human PD-1 at a concentration of 1 µg/ml. After washing and blocking with PBST+5% BSA, a pre-incubated mixture of pembrolizumab (0.3 µg/ml), spiked with increasing concentrations of Human Anti-Pembrolizumab Antibody, clone AbD30689 (HCA296) was added. Free pembrolizumab, still capable of binding to the human PD-1 coated plate, was detected using a Mouse Anti-Human IgG (Fc) CH2 Domain:HRP Antibody (MCA647P) followed by QuantaBlu Fluorogenic Peroxidase Substrate. Data are shown as the mean of three measurements.

Antibody Quality and Performance Guarantee
| Human Anti-Pembrolizumab Antibody, clone AbD30689 is a paratope specific, inhibitory anti-idiotypic antibody that specifically recognizes the free humanized monoclonal antibody pembrolizumab. The antibody does not recognize recombinant human programmed cell death 1 (PD-1) or pembrolizumab in complex with recombinant human PD-1 and can be used to measure free pembrolizumab levels in serum from patients. A pair of anti-pembrolizumab antibodies can be used to develop a pharmacokinetic (PK) bridging assay to measure free drug. This antibody, in monovalent Fab format, is recommended as the capture antibody, paired with an HRP conjugated Anti-Pembrolizumab Antibody in full immunoglobulin format, clone AbD30685_hIgG1 (HCA297) as the detection antibody. Pembrolizumab (Keytruda) is a humanized (IgG4/kappa) antibody with the heavy chain mutation S228P (IgG4-Pro). Pembrolizumab is used to treat inoperable or metastatic melanoma, metastatic non-small cell lung cancer (NSCLC), and as a second-line treatment for head and neck squamous cell carcinoma (HNSCC). Pembrolizumab is a first line treatment for NSCLC if the cancer overexpresses PDL1 and has no mutations in EGFR or ALK. Pembrolizumab is a checkpoint inhibitor and acts as an immunomodulator by blocking ligand activation of PD-1 receptor on T cells, thereby activating T cells to attack the cancer. It blocks PD-1 interaction with PD-1 ligand (PD-L1) and PD-1 ligand 2 (PD-L2). View a summary of all anti-pembrolizumab antibodies |
