商品描述
Human Anti-Ustekinumab Antibody, clone AbD17827_hIgG1 is a paratope specific, high affinity, anti-idiotypic antibody that specifically recognizes the monoclonal antibody drug ustekinumab and inhibits binding to its target. The antibody can be used to measure the levels of ustekinumab and biosimilar products in bioanalytical assays.Clone AbD17827_hIgG1 is a fully human recombinant monoclonal antibody with IgG1 isotype and is suitable as a surrogate positive control or calibrator in an anti-drug antibody (ADA) assay. Additionally it can be used to develop a pharmacokinetic (PK) bridging assay to measure free drug. This antibody is recommended as the detection antibody, paired with an anti-ustekinumab antibody in monovalent Fab format as the capture antibody, clone AbD17829 (HCA208) or clone AbD18334 (HCA209).Ustekinumab (Stelara) is a fully human monoclonal antibody drug (IgG1/kappa) that has been approved in US, Canada, and Europe for the treatment of plaque psoriasis and psoriatic arthritis. The FDA approved the medication for the treatment of moderate-severe Crohn"s disease in 2016. The drug blocks interleukin IL-12 and IL-23 by binding with high affinity and specificity to the p40 subunit, preventing the binding of these two cytokines to T-lymphocytes, and thereby disrupting the proinflammatory pathway.View a summary of all anti-ustekinumab antibodies
