Human anti cetuximab specificity ELISA

A microtiter plate was coated over night with various antigens at a concentration of 5 µg/ml. After washing and blocking with PBST+5% BSA, detection was performed using Human anti cetuximab (clone AbD19834) at a concentration of 2 µg/ml, followed by Mouse anti histidine tag:HRP (MCA5995P) in HISPEC assay diluent (BUF049A) and QuantaBlu™ fluorogenic peroxidase substrate

Human anti cetuximab specificity titration ELISA

A microtiter plate was coated over night with human IgG1/kappa, human IgG1/lambda, rituximab or cetuximab at a concentration of 5 µg/ml. After washing and blocking with PBST+5% BSA, detection was performed using Human anti cetuximab (clone AbD19834) titrated to the given concentrations in PBST+10% human serum, followed by Mouse anti histidine tag:HRP (MCA5995P) in HISPEC assay diluent (BUF049A) and QuantaBlu™ fluorogenic peroxidase substrate

Cetuximab bridging ELISA for Pharmacokinetic (PK) assay development

A microtiter plate was coated over night with Human anti cetuximab (clone AbD19834) 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 cetuximab. Detection was performed using HRP-conjugated Human anti cetuximab (clone AbD19830_hIgG1, HCA221) at a concentration of 2 µg/ml in HISPEC assay diluent (BUF049A) and QuantaBlu™ fluorogenic peroxidase substrate. HRP-conjugation of the antibody used in this assay was performed using a LYNX Rapid HRP Antibody Conjugation Kit®

Cetuximab bridging ELISA for Pharmacokinetic (PK) assay development with Type 2 detection antibody

A microtiter plate was coated over night with Human anti cetuximab (clone AbD19834, HCA220) at a concentration of 5 µg/ml. After washing and blocking with PBST+5% BSA, 10% human serum was added spiked with increasing concentrations of cetuximab. Detection was performed using HRP-conjugated Human anti cetuximab (Type 2 clone AbD19376_hIgG1, HCA228) at a concentration of 2 µg/ml in HISPEC assay diluent (BUF049A) and QuantaBlu™ fluorogenic peroxidase substrate. HRP-conjugation of the antibody used in this assay was performed using a LYNX Rapid HRP Antibody Conjugation Kit®.

Cetuximab inhibition ELISA

A microtiter plate was coated over night with EGFR at a concentration of 1 µg/ml. After washing and blocking with PBST+5% BSA, a pre-incubated mixture of cetuximab (CTX, 0.3 µg/ml) plus increasing concentrations of Human anti cetuximab (HCA220, HCA221 or HCA223 or the non-inhibitory HCA228) was added. For this assay, HCA221, HCA223 and HCA228 were used in their monovalent Fab format. Free cetuximab, still capable of binding to the EGFR-coated plate, was detected using Goat anti Human IgG F(ab')2:HRP (STAR126P)

      • Human anti Cetuximab, clone AbD19834, is an anti-idiotypic antibody that binds specifically to cetuximab and inhibits the binding of the drug to its target, epidermal growth factor receptor (EGFR). It can be used in bioanalytical assays to measure the levels of cetuximab and biosimilar products in preclinical research and clinical trials.

        Clone AbD19834 is particularly suited as a capture antibody in a pharmacokinetic (PK) assay when used in combination with HRP-conjugated detection antibody. With anti cetuximab clone AbD19830 (HCA221), another inhibitory antibody, free drug can be measured. Alternatively, when used with a non-inhibitory anti cetuximab antibody, clone AbD19376 (HCA228), total drug can be measured (free, partially bound and fully bound).

        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 is directed against EGFR and inhibits tumor cell proliferation by blocking the interaction of epidermal growth factor (EGF) with its receptor.
