Recombinant muis IL-12 p70 eiwit

IL12b/IL12a, also known as interleukin 12 (subunit beta/alpha), is a cytokine that can act as a growth factor for activated T and NK cells, enhance the lytic activity of NK/lymphokine-activated killer cells, and stimulate the production of IFN-gamma by resting PBMC. It is a key mediator of cellular-immunity and induces the differentiation of Th1 cells from precursor T helper cells. As it is associated with IL23A to form the IL-23 interleukin, it induces autoimmune inflammation and is responsible for autoimmune inflammatory diseases and may be important for tumorigenesis. Recombinant mouse IL12b/IL12a protein, fused to His-tag at C-terminus, was expressed in insect cell and purified by using conventional chromatography techniques.

Mouse IL12 stimulates IFN-g secretion of the NK-92 human natural killer cells. The ED50 range is less or equal to 10 ng/mL.
