Mouse IL-12(p40) ELISA Kit - 1 Kit (96 Wells)Our Mouse IL-12(p40) ELISA Kit is a sandwich ELISA intended for the quantitative determination of mouse IL-12 (p40) in cell culture supernates, serum and plasma (heparin, EDTA, citrate).
Interleukin-12(IL12, formerly NKSF, for natural killer cell stimulatory factor, or CLMF, for cytotoxic lymphocyte maturation factor) is a novel cytokine cloned from B-cell lines. IL-12 is a heterodimeric molecule composed of p35 and p40 subunits.1 The larger 40-kDa subunit(p40) is a member of the cytokine receptor family, and the smaller 35-kDa subunit(p35) is related to IL6 and GCSF.2 Both IL-12 p40(-/-) and p35(-/-) mice fail to produce IL-12 p70 heterodimer.3 Interleukin(IL)-12 has been cloned on the basis of its ability to activate natural killer(NK) cells and promote the development of cytolytic T cells. With further understanding of its activities, IL-12 has emerged as an important cytokine, affecting both immune and hematologic functions. It has been shown to be necessary for the T cell independent induction of interferon(IFN)-gamma, critical for the initial suppression of bacterial and parasitic infection; for the development of a Th1 response, critical for effective host defense against intracellular pathogens; and for the activation of differentiated T lymphocytes of both CD4 and CD8 phenotype.
