Mouse interleukin-12p70 (IL-12p70) is a disulfide-linked heterodimer consisting of IL-12a (p35 subunit) and IL-12b (p40 subunit) that is mainly produced by macrophages and T lymphocytes. The IL-12a subunit also dimerizes with Ebi3 to form IL-35, and the IL-12b subunit dimerizes with IL-23a to form IL-23. IL-12, IL-23, IL-27, and IL-35 are all heterodimeric proteins and members of IL-12 cytokine family. IL-12p70 activates T cells and natural killer cells that stimulate the production of IFN-γ. It is involved in a number of disorders including peritonitis and chronic toxoplasmosis.The Mouse IL-12p70 Kit provides assay-specific components for the quantitative determination of endogenous IL-12p70 in mouse urine, serum, plasma, and cell culture supernatants.
