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-Tremelimumab Antibody, clone AbD64580ad (TZA0127) at a concentration of 2 μg/mL in PBST followed by an HRP labelled anti-DYKDDDDK tag antibody in HISPEC Assay Diluent (BUF049A) and QuantaBlu fluorogenic peroxidase substrate.
A microtiter plate was coated overnight with Tremelimumab, human CTLA-4, 10% NHS, 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 Human Anti-Tremelimumab Antibody, clone AbD64580ad (TZA0127) titrated to the given concentrations in PBST followed by an HRP conjugated Anti-DYKDDDDK tag Antibody in HISPEC diluent (BUF049A) and QuantaBlu Fluorogenic Peroxidase Substrate. Data for tremelimumab are shown as the mean of three measurements.
A microtiter plate was coated overnight with Human Anti-Tremelimumab Antibody, clone AbD64576ad (TZA0126) 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 tremelimumab. Detection was performed using HRP conjugated Human Anti-Tremelimumab Antibody, clone AbD64580pap (TZA127P) at a concentration of 0.5 µg/mL in HISPEC Assay Diluent (BUF049A) and QuantaBlu fluorogenic peroxidase substrate. Data are shown as the mean of three measurements.
Filter by Application:
E Reset| Human Anti-Tremelimumab Antibody, clone AbD64580 is a paratope specific, inhibitory anti-idiotypic antibody (Type 1) that specifically recognizes the humanized monoclonal antibody drug tremelimumab. It does not recognize the drug target CTLA-4, nor tremelimumab in complex with CTLA-4. This antibody can be used to measure free tremelimumab levels in serum from patients. TZA0127 is available as a monovalent Fab antibody incorporating a SpyTag at the C-terminus end of the antibody heavy chain for conversion by the end user into alternative formats using any of the SpyCatchers available in our catalog under product code TZA0127. It is also available as a bivalent Fab antibody already conjugated to HRP via coupling to the HRP conjugated BiSpyCatcher2 (TZC002P) for use in direct ELISA under product code TZA0127P. A pair of anti-tremelimumab antibodies can be used to develop a pharmacokinetic (PK) bridging assay to measure free drug; clone AbD64580 is recommended as a detection antibody, paired with Human Anti-Tremelimumab Antibody, clone AbD64576ad (TZA0126) as the capture antibody. Tremelimumab (trade name Imjudo) is a fully humanized monoclonal IgG2/kappa antibody with allotype IGHG2*01. It binds to cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) to enhance T cell-mediated killing of tumours and reduces tumour growth. Tremelimumab in combination with durvalumab and platinum-based chemo-therapy is indicated for the first-line treatment of adults with metastatic non-small cell lung cancer (NSCLC) with no sensitising EGFR mutations or ALK positive mutations.
