商品描述
Human Anti-Golimumab Antibody, clone AbD25455 is an anti-idiotypic antibody that specifically recognizes the monoclonal antibody drug golimumab. This antibody binds to both free golimumab and to golimumab bound to its target tumor necrosis factor alpha (TNFα). Clone AbD25455 does not inhibit the binding of golimumab to its target TNFα and can be used to measure total golimumab and biosimilar products in bioanalytical assays.Clone AbD25455 is an affinity-matured variant of clone AbD20897 (HCA242), with about 7-fold affinity improvement.A pair of anti golimumab antibodies can be used to develop a pharmacokinetic (PK) bridging assay to measure free drug. This antibody, in monovalent Fab format, is recommended as the capture antibody, paired with an antibody in full immunoglobulin format, clone AbD25451_hIgG1 (HCA290), as the detection antibody.Golimumab, marketed under the brand name Simponi is a recombinant human IgG1/kappa monoclonal antibody approved for the treatment of rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis. This therapeutic antibody, directed against TNFα, acts by blocking the binding of TNFα to its receptors, resulting in a down-regulation of the inflammatory response associated with autoimmune diseases.View a summary of all anti-golimumab antibodies
