Human Anti-Infliximab, clone AbD17841_hIgG1 is an anti-idiotypic antibody that specifically recognizes the infliximab monoclonal antibody and inhibits the binding of infliximab to its target. It can be used in bioanalytical assays to measure the levels of infliximab and biosimilar products, such as Inflectra and Renflexis, in patient samples.

Human anti Infliximab, clone AbD17841_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 AbD17841_IgG1 is suitable as a detection antibody in pharmacokinetic (PK) assays.

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.
