HCA207 Antigen-Capture Assay using the Adalimumab/TNFa complex binder HCA207 for detection. Human TNFα was used as the coating antigen followed by Adalimumab spiked into 10% human serum. Human anti-Adalimumab/TNFα antibody HCA207 (conjugated to HRP) was used as the detection reagent
Anti-adalimumab drug-target complex antibody specifically recognizes the adalimumab-TNF alpha complex exclusively and detects adalimumab or biosimilars only when bound to TNF alpha. This antibody is in full immunoglobulin format and is suitable for a PK antigen capture format assay.

Human anti Adalimumab, clone AbD18754_hIgG1, is an antibody that specifically recognizes the adalimumab monoclonal antibody while complexed with TNFα. As clone AbD18754_hIgG1 is a complex-specific antibody that recognizes adalimumab bound to its target, TNFα, it does not recognize either free adalimumab or unbound TNFα.
Clone AbD18754_hIgG1 can be used in assays to measure adalimumab that has been captured via immobilised TNFα. It can also be used to measure adalimumab/TNFα and biosimilar products using bioanalytical assays.
Adalimumab (branded as Humira®) is a fully human monoclonal antibody (IgG1/kappa) approved for the treatment of ankylosing spondylitis, Crohn’s disease, psoriasis and several forms of arthritis. The antibody is specific for TNFα, and acts by blocking the activation of TNF receptors by TNFα. This inactivation down-regulates the inflammatory reactions associated with autoimmune diseases.
Human IgG1 antibody selected from the HuCAL® phage display library and expressed in a human cell line. This antibody is supplied as a liquid.
Purified IgG prepared by affinity chromatography on Protein A from tissue culture supernatant
The monovalent intrinsic affinity of this antibody was measured as KD=67 nM by real time, label-free molecular interaction analysis on immobilized adalimumab/TNFα.
