Ustekinumab antibody | AbD17829
Human anti Ustekinumab
Anti-ustekinumab antibody is a recombinant, neutralizing anti-idiotypic antibody in monovalent Fab format; it is ideal for bioanalytical assay development for ustekinumab and biosimilars. This antibody is recommended as capture antibody in PK bridging ELISA format with HCA210/HCA210P for detection.

A pair of anti-ustekinumab antibodies can be used to develop a pharmacokinetic (PK) bridging assay to measure free drug. This antibody, in monovalent Fab format, is recommended as a capture antibody, paired with an HRP conjugated Anti-Ustekinumab Antibody in full immunoglobulin format, clone AbD17827_hIgG1 (HCA210) as the detection antibody.
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.
