Lyophilized Standard Mix-Human Group 1 Panel A, 7-Plex. PN: NG10007. One vial containing lyophilized recombinant NHP IFNγ, IL-2, IL-4, IL-6, IL-10, IL-17A, and TNFα. Note: If multiple analyte kits on the above target list are ordered as a panel, only one vial of standard mix is supplied for those analyte kits.
STORAGE: 2-8 C in the dark.
IMPORTANT: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

IL-12 is a cytokine composed by two different subunits: IL-12p35 (MW 35 kDa) + IL-12p40 (MW 40 kDa). So, the entire cytokine is considered IL-12p70, its total MW is around 70 kDa. IL-12 is involved in the differentiation of naive T cells into Th1 cells. It is known as a T cell-stimulating factor, which can stimulate the growth and function of T cells. It stimulates the production of interferon-gamma (IFN-γ) and tumor necrosis factor-alpha (TNF-α) from T cells and natural killer (NK) cells, and reduces IL-4 mediated suppression of IFN-γ. T cells that produce IL-12 have a co-receptor, CD30, which is associated with IL-12 activity. IL-12 plays an important role in the activities of natural killer cells and T lymphocytes. IL-12 mediates enhancement of the cytotoxic activity of NK cells and CD8+ cytotoxic T lymphocytes.
