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 Human IL-12 p70, derived from HEK293 cells, is a heterodimeric glycoprotein consisting of disulfide-linked p35 and p40 subunits (503 total amino acid residues) . The calculated molecular weight of Human IL-12 p70 is 57.2 kDa; however, due to glycosylation, it migrates at an apparent molecular weight of 65-70 kDa based on SDS-PAGE gel, under non-reducing conditions.
