Trastuzumab antibody | AbD18018_hIgG1
A microtiter plate was coated overnight with trastuzumab at a concentration of 0.5 µg/ml. After washing and blocking with PBST+5% BSA, Human Anti-Trastuzumab Antibody clone AbD18018_hIgG1 (HCA177) in PBST + 10% Human Serum was added. Detection was performed using HRP conjugated trastuzumab at a concentration of 2 µg/ml in HISPEC Assay Diluent (BUF049A) and QuantaBlu Fluorogenic Peroxidase Substrate.
A microtiter plate was coated overnight with Human Anti-Trastuzumab Antibody, clone AbD16712 (HCA166) (black) and Human Anti-Trastuzumab Antibody, clone AbD18141 (HCA169) (red) 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 trastuzumab. Detection was performed using HRP conjugated Human Anti-Trastuzumab Antibody, clone AbD18018_hIgG1 (HCA177P) at a concentration of 2 µg/ml in HISPEC Assay Diluent (BUF049A) and QuantaBlu Fluorogenic Peroxidase Substrate.
A microtiter plate was coated overnight with various antigens at a concentration of 5 μg/ml. After washing and blocking with PBST + 5% milk powder, detection was performed using HRP conjugated Human Anti-Trastuzumab Antibody, clone AbD18018_hIgG1 (HCA177P) at a concentration of 1 μg/ml in HISPEC Assay Diluent (BUF049A) followed by QuantaBlu Fluorogenic Peroxidase Substrate.

Antibody Quality and Performance Guarantee
| Human Anti-Trastuzumab Antibody, clone AbD18018_hIgG1, is a paratope specific, high affinity, anti-idiotypic antibody that specifically recognizes the monoclonal antibody drug trastuzumab and inhibits it binding to its target. The antibody can be used to measure the levels of trastuzumab and biosimilar products in bioanalytical assays. Clone AbD18018_hIgG1 is a fully human recombinant monoclonal antibody with IgG1 isotype and is suitable as a reference standard in an anti-drug antibody (ADA) assay. Additionally the antibody can be used to develop a pharmacokinetic (PK) bridging assay to measure free drug in preclinical research and clinical trials using patient sera. This antibody, in full immunoglobulin format and conjugated to HRP, is recommended as the detection antibody, paired with antibody clone AbD16712 (HCA166) or clone AbD18141 (HCA169), both monovalent Fab format, as the capture antibody. This clone is also available in IgG4 isotype format (HCA270) in order to offer assay developers increased flexibility in assay design. When used as an ELISA detection antibody, a secondary anti-human IgG4 antibody is required, which can be labeled according to the needs of the user's preferred assay platform. Trastuzumab, also known as Herceptin, is a drug used in the treatment of HER2 positive breast cancer and other HER2 over-expressing cancers including HER2-positive metastatic cancers of the gastrointestinal tract. Trastuzumab binds to the HER2 (or c-erbB2) proto-oncogene, an EGF receptor-like protein found on 20-30% of breast cancer cells. The binding leads to antibody mediated (complement mediated) killing of the HER2 positive cells. View a summary of all Anti-Trastuzumab Antibodies |
