Human anti Cetuximab, clone AbD19830_hIgG1, is an anti-idiotypic antibody that binds specifically to cetuximab and inhibits the binding of the drug to its target. Human anti Cetuximab, clone AbD19830_hIgG1 can be used to measure the levels of cetuximab and biosimilar products using bioanalytical assays.

In the HRP-conjugated format clone AbD19830_hIgG1 is ideal for use as detection antibody in pharmacokinetic (PK) assays. It is a fully human antibody and therefore may also be used as a calibrator in immune response assays to measure the anti-drug-antibody (ADA) response in patient sera.

Cetuximab (brand name Erbitux®) is a chimeric monoclonal antibody drug (IgG1/kappa) approved for treatment of KRAS wild-type metastatic colorectal cancers and squamous cell carcinoma of the head and neck. This therapeutic antibody, directed against the Epidermal Growth Factor Receptor (EGFR), inhibits tumor cell proliferation by blocking the interaction of Epidermal Growth Factor (EGF) with its receptor.
