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).
