recombinant Interleukin-12p40 comprises a 306 amino acid fragment (23-328) corresponding to the mature Interleukin-12p40 chain protein and is expressed in E. coli with an amino-terminal hexahistidine tag.
Active IL-12 is a p70 disulphide-linked dimer composed of p35 and p40 subunits. The protein is a pleiotropic cytokine produced primarily by antigen presenting cells and has multiple effects on T lymphocytes and natural killer cells in terms of stimulating cytotoxicity, proliferation, production of other cytokines and Th1 subset differentiation.,IL-12B, subunit p40, cytotoxic lymphocyte maturation factor 2, p40, natural killer cell stimulatory factor 2, CLMF, CLMF2, NKSF, NKSF2.
