IL-12 p70

IL-12 is a potent regulator of cell-mediated immune responses and it induces IFN-γ production by NK and T cells. It is produced by activated monocytes/macrophage cells, B lymphocytes and connective tissue-type mast cells. Among its biological activities, IL-12 promotes the growth and activity of activated NK, CD4+ and CD8+ cells, and induces the development of IFN-γ-producing Th1 cells. Recombinant Murine IL-12 is a 75.0 kDa heterodimeric glycoprotein consisting of disulfide-linked 35 kDa (p35) and 40 kDa (p40) subunits (506 total amino acid residues) .

< 0.1 ng/µg of protein (< 1EU/µg)

≥ 98% by SDS-PAGE gel and HPLC analyses

Determined by its ability to induce cell proliferation in T-cell enriched PBMCs. The expected ED50 is ≤ 0.1 ng/ml, corresponding to a specific activity of ≥ 1 x 107 units/mg.
