Human anti Infliximab:HRP

Anti-infliximab antibody is a non-neutralizing anti-idiotypic antibody in IgG1 format, ideal for bioanalytical assays for infliximab and biosimilars. It does not inhibit the binding of infliximab to TNF alpha; it is ideal for PK bridging ELISA to measure total drug and as calibrator in ADA assay.

Human anti Infliximab, clone AbD19376_hIgG1, is an anti-idiotypic antibody that binds to both free infliximab and to infliximab bound to its target, TNFα. Clone AbD19376_hIgG1 does not inhibit the binding of infliximab to TNFα. It can be used in bioanalytical assays to measure the levels of infliximab and biosimilar products, such as Inflectra and Renflexis, in patient samples.

Clone AbD19376_hIgG1 binds to an epitope outside the infliximab binding site. This epitope is shared with other chimeric antibodies that are highly homologous to infliximab including the chimeric antibody cetuximab but not rituximab.

Human anti Infliximab, clone AbD19376_hIgG1 is a fully human antibody and may be used to develop and calibrate immune response assays to measure the anti-drug antibody (ADA) response in patient sera. In the HRP-conjugated format, clone AbD19376_IgG1 is suitable as a detection antibody in pharmacokinetic (PK) assays to measure total infliximab levels (free drug, partially bound and fully bound).

Infliximab (branded as Remicade®) is a chimeric monoclonal antibody drug (IgG1/kappa) that has been approved for treatment of psoriasis, Crohn's disease, ankylosing spondylitis, psoriatic arthritis, rheumatoid arthritis, and ulcerative colitis.

Infliximab is directed against Tumor Necrosis Factor Alpha (TNFα) and acts by blocking the binding of this cytokine to its receptors. Infliximab also induces apoptosis of TNFα expressing T-lymphocytes.
