Catalog Number:
210-12
Synonyms:
NKSF, CTL maturation factor （TCMF）, Cytotoxic lymphocyte maturation factor （CLMF）, TSF
Description:
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）.
