Human Anti-Trastuzumab Antibody, clone AbD18018, is a paratope specific, high affinity, anti-idiotypic antibody that 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 AbD18018 is a fully human recombinant monoclonal antibody in monovalent Fab format and is suitable as a capture or detection antibody paired with antibody clone AbD16712 (HCA166) in a pharmacokinetic (PK) bridging ELISA, to measure free drug in preclinical research and clinical trials using patient sera.Human Anti-Trastuzumab Antibody, clone AbD18018 is also available in full immunoglobulin format as IgG1 isotype (HCA177) or IgG4 isotype (HCA270) in order to offer assay developers increased flexibility in assay design.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.
- Product Form
- A monovalent human recombinant Fab (lambda light chain) selected from the HuCAL® phage display library, expressed in E. coli. The antibody is tagged with a DYKDDDDK tag and a HIS-tag (HHHHHH) at the C-terminus of the antibody heavy chain. This antibody is supplied as a liquid.
- Preparation
- Metal chelate affinity chromatography
- Buffer Solution
- Phosphate buffered saline.
- Preservative Stabilisers
- 0.01% Thiomersal
- Immunogen
- Trastuzumab
- Affinity
- HCA168 is an ultra-high affinity idiotype antibody that specifically recognises the Herceptin humanised monoclonal antibody. The monovalent intrinsic affinity of HCA168 was measured as 0.02nM by real time, label-free molecular interaction analysis using an Attana A200 instrument on immobilized Herceptin.
