Human anti Infliximab, clone AbD20436, is an affinity matured anti-idiotypic antibody in monovalent Fab format that specifically recognizes free infliximab but not infliximab bound to its target, Tumor Necrosis Factor Alpha (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.

Human anti Infliximab, clone AbD20436 inhibits the binding of infliximab to TNFα and can be used as a capture antibody in a pharmacokinetic (PK) assay in the bridging format to measure free drug.

Infliximab (branded as Remicade®) is a chimeric IgG1 kappa monoclonal antibody approved for the treatment of psoriasis, Crohn's disease, ankylosing spondylitis, psoriatic arthritis, rheumatoid arthritis and ulcerative colitis. Infliximab is directed against TNFα and acts by blocking the binding of TNFα to its receptors, resulting in a down-regulation of the inflammatory response associated with autoimmune diseases.
