Biological ActivityAssay #1: The ED50 as determined by the induction of IFN-γ from NK cells co-stimulated with IL-18 is ≤ 1.0 ng/ml, corresponding to a specific activity of ≥ 1 x 106 units/mg. Assay #2: Determined by its ability to increase IFN-γ production by anti-TCR mAb-stimulated PBMCs. The expected ED50 for this effect is 4.0-8.0 ng/ml.
Species ReactivityMonkley, Mouse, Human, Leech
SynonymsInterleukin-12, NKSF, CTL Maturation Factor (TCMF), Cytotoxic Lymphocyte Maturation Factor (CLMF), TSF
DescriptionIL-12 is a potent regulator of cell mediated immune responses and it induces IFN-gamma 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-gamma producing Th1 cells. Recombinant Human IL-12 is a 75.0 kDa heterodimeric glycoprotein consisting of disulfide-linked 35 kDa (p35) and 40 kDa (p40) subunits (503 total amino acid residues).
