Trastuzumab antibody | AbD18141
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, Human Anti-Trastuzumab Antibody clone AbD18141 (HCA169) was added at a concentration of 2 μg/ml. Detection was performed using Mouse Anti-Penta Histidine Tag:HRP Antibody (MCA5995P) in HISPEC Assay Diluent (BUF049A) and QuantaBlu Fluorogenic Peroxidase Substrate.
A microtiter plate was coated overnight with Human Anti-Trastuzumab Antibody, clone AbD18141 (HCA169) at a concentration of 5 μg/ml. After washing and blocking with PBST+5% BSA, increasing concentrations of trastuzumab in PBST was added. Detection was performed using Mouse Anti-Human IgG (Fc) CH2 Domain:HRP Antibody (MCA647P) in HISPEC Assay Diluent (BUF049A) and QuantaBlu Fluorogenic Peroxidase Substrate. Data is presented as the mean of three measurements.
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 Human Anti-Trastuzumab:HRP Antibody, clone AbD16712_hIgG1 (HCA176P) at a concentration of 2 µg/ml in HISPEC Assay Diluent (BUF049A) and QuantaBlu Fluorogenic Peroxidase Substrate.

Antibody Quality and 
Unrivaled 
| Human anti-Trastuzumab Antibody, clone AbD18141, 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. Human Anti-Trastuzumab Antibody, clone AbD18141 is a fully human recombinant monoclonal antibody in monovalent Fab format and is suitable as a capture antibody paired with antibody clone AbD16712_hIgG1 (HCA176P) in a pharmacokinetic (PK) bridging ELISA, to measure free drug in preclinical research and clinical trials using patient sera. 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. |
