HUMAN ANTI ETANERCEPT

Human anti etanercept, clone AbD25940_hIgG4_Pro is an antibody that specifically recognizes etanercept as well as the extracellular ligand-binding portion of the 75 kDa (p75) human tumor necrosis factor receptor 2 (TNFR2). Clone AbD25940_hIgG4_Pro inhibits the binding of etanercept to its target tumour necrosis factor alpha (TNFα). The antibody binds to free etanercept but not to etanercept bound to its target TNFα. The antibody binds to an epitope which is also part of the TNFα binding site and can be used to measure the levels of etanercept and biosimilar products (e.g. Etacept, Intacept) in bioanalytical assays.CloneAbD25940_hIgG4_Pro is a fully human recombinant monoclonal antibody with an IgG4 isotype and is suitable as a reference standard in an anti-drug antibody (ADA) assay. Additionally the antibody can be used to develop a pharmacokinetic (PK) bridging assay to measure free drug. This antibody, in full immunoglobulin format, is recommended as the detection antibody, paired with the antibody clone AbD25939 (HCA276) in monovalent Fab format, as the capture antibody.Etanercept (Enbrel^®) is a dimeric fusion protein consisting of the extracellular ligand-binding portion of the human 75 kDa (p75) TNFR2 linked to the Fc portion of human IgG1. The Fc component of etanercept contains the CH2 domain, the CH3 domain and hinge region, but not the CH1 domain of IgG1. It is used to treat autoimmune diseases by interfering with TNF, acting as a TNF inhibitor. It binds to both TNFα and TNFβ (Lymphotoxin A).View a summary of all anti-etanercept antibodies.
