概要
Interleukin 12 (IL-12p70) is a heterodimeric cytokine composed of p35 and p40 subunits. IL-12 is produced by monocytes, macrophages, dendritic cells, neutrophils, and B cells in response to bacterial products and cytokines such as IFN-γ. The IL-12 receptor is expressed on T, NK, and dendritic cells. Upon binding, IL-12 initiates signaling via the JAK/STAT signaling pathway and stimulates NK, B, and T cells to produce IFN-γ (Watford et al.). It also regulates cytokine synthesis, proliferation of T and NK cells, and stimulates differentiation of CD4+ and CD8+ T cells (Germann & Rüde). Mice that are deficient in IL-12 are susceptible to many intracellular pathogens and have impaired IFN-γ secretion, Th1 differentiation, and NK cytolytic activity; however, Th2 development and IL-4 production are enhanced (Watford et al.).

Data
(A) The biological activity of Human Recombinant IL-12 was tested by its ability to produce IFN-gamma in NK cells co-stimulated with
IL18.
The EC50 is defined as the effective concentration of the growth factor at which IFN-gamma production is at 50% of maximum. The
EC50 in the above example is less than 2 ng/mL.
(B) 2 μg of Human Recombinant IL-12 was resolved with SDS-PAGE under reducing (+) and non-reducing (-) conditions and visualized
by Coomassie Blue staining. Human Recombinant IL-12 has a predicted molecular mass of 22.5 - 34.7 kDa.
