IL 12 ELISA kits are assays designed to detect interleukin 12, a heterodimeric cytokine encoded by the genes IL-12A (p35) and IL-12B (p40). Also known as T-cell stimulating factor, it aids in the differentiation of naïve T cells into Th1 cells. It also stimulates the production of IFN-γ, TNF-α, and natural killer cells. It is secreted by dendritic and phagocytic cells. IL-12 is involved in immune resistance against a variety of microbial diseases, including HIV and influenza. IL 12 ELISA kits can be useful in studying cytokine signaling and immune responses. Visit the supplier page for more information about detection target, range, origin, and reactivity.
