Ustekinumab (branded as Stelara®) is a fully human monoclonal antibody drug (IgG1/kappa) that has been approved for treatment of moderate to severe psoriasis. Ustekinumab is also being investigated for the treatment of psoriatic arthritis, for multiple sclerosis and sarcoidosis. Studies indicate that it may also have potential for treating severe Crohns disease.
Ustekinumab is directed against the p40 subunit of interleukin-12 and interleukin-23 and acts by blocking the binding of these two cytokines to, and preventing activation of, T-lymphocytes.

Human anti Ustekinumab antibody, clone AbD17829_hIgG1 is an anti-idiotypic antibody that specifically recognises the Ustekinumab monoclonal antibody and inhibits the binding of Ustekinumab to its target. It can be used to measure Ustekinumab levels in serum from patients.
