Human Anti-Certolizumab pegol Antibody, clone AbD34136ia, is a paratope specific, inhibitory anti-idiotypic antibody that specifically recognizes the free humanized Fab fragment antibody certolizumab pegol. The antibody does not recognize human Tumor Necrosis Factor alpha (TNFα) or certolizumab pegol in complex with human TNFα.

Clone AbD34136ia is a fully human recombinant monoclonal antibody with IgG1 isotype and is suitable as a surrogate positive control or reference standard in an anti-drug antibody (ADA) assay. This antibody has a monovalent intrinsic affinity of 3 nM, and is one of three antibodies with different affinities offered for ADA assays. Antibody HCA325 has affinity 1 nM and HCA326 has affinity 2 nM.

Certolizumab pegol (Cimzia) is a humanized Fab fragment antibody (50 kDa), covalently bound to two polyethylene glycol (PEG) chains (PEG2MAL, 40 kDa) via a thioether linkage; total molecular weight 90.8 kDa. PEG helps to delay the metabolism and elimination of the drug. The removal of the Fc region increases the half-life of the drug and prevents complement fixation and antibody-mediated cytotoxicity. The drug is approved for the treatment of Crohn's disease, rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis. It binds to free and membrane-bound human TNFα and neutralizes its activity by inhibiting the binding of TNFα to human p55 and p75 TNF receptors.
