Interleukin 12 (subunit beta/alpha), IL12b/IL12a, Il-12b/Il-12a, IL-12p40/Il-12p35, Il12p40/Il12p35, p40/p35, Sf9.
interleukin 12 subunit beta/alpha or IL12b/IL12a is a growth factor cytokine which increases the lytic activity of NK/lymphokine-activated killer cells, activated T and NK cells and prompt IFN-gamma production (through resting PBMC). IL12b/IL12a is a crucial part to the process of cellular-immunity and activates the differentiation of Th1 cells originates from the precursor T helper cells. The protein is linked to IL23A and creates the IL-23 interleukin, by that, the autoimmune inflammation is induced and autoimmune inflammatory diseases and tumorigenesis are being affected.
IL12 Mouse Recombinant produced in a baculovirus expression system is a glycosylated disulfide linked (through cysteines in bold) heterodimer comprised of IL12A (23-335aa, total of 319 aa, MW 35.7kDa) and IL12B (23-215aa, total of 199 aa, MW 22.5kDa), having a total predicted molecular mass of 58.3kDa (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.
