IL-12 IL-23

Ustekinumab is a human monoclonal antibody that prevents human IL-12 and IL-23 from binding to the IL-12Rβ1 receptor chain of IL-12 (IL-12Rβ1/β2) and IL-23 (IL-12Rβ1/23R) receptor complexes on the surface of natural killer cells and T-cells. Ustekinumab is a human IgG1 kappa (κ) monoclonal antibody against the IL-12/IL-23 p40 subunit that prevents its interaction with IL-12Rβ1, thereby blocking subsequent signaling. The FcRn affinities at pH 6.0 fell in a narrow range for all 11 antibodies. The equilibrium dissociation constant (KD) is calculated relative to Ustekinumab (Ustekinumab=1.0). has not independently confirmed the accuracy of these methods. They are for reference only.
