IL12 His Recombinant Protein

Source : Baculovirus. IL12 Human Recombinant produced in a baculovirus expression system is a glycosylated disulfide linked (through cysteines in bold) heterodimer comprised of IL12A (23-219aa, total of 203 aa, MW 23.3kDa) and IL12B (23-328aa, total of 306 aa, MW 34.6kDa), having a total predicted molecular mass of 57.9kDa (Molecular weight on SDS-PAGE will appear higher) .IL12A is fused to a 6 amino acid His-Tag at C-terminus and purified by proprietary chromatographic techniques. IL-12 is a heterodimeric cytokine that stimulates the production of interferon gamma from T-cells and natural killer cells, and also induces differentiation of Th1 helper cells. IL-12 is an initiator of cell-mediated immunity.
