Mouse IL-12

Mouse IL-12

IL-12 stands for interleukin 12. Mouse IL-12 is a recombinant protein optimized for use in cell culture, differentiation studies, and functional assays.


Mouse IL-12 can be used for a variety of applications, including:
  • In vitro activation and proliferation of NK and T cells.
  • In vitro differentiation of naive CD4+ T cells towards TH 1 cells.
  • In vitro stimulation of cytotoxic activity of NK cells and T cells.

Background information

Interleukin 12 (IL-12) is a heterodimeric proinflammatory cytokine and a modulator of cell-mediated immunity, which is mainly produced by macrophages, dendritic cells, and B cells. IL-12 stimulates the production and secretion of several cytokines, in particular IFN-γ, by NK cells and T cells, induces proliferation, and enhances the cytotoxic activity within these cell populations. Another important activity of IL-12, acting together with IFN-γ and IL-2, is to drive T helper cell responses toward the T
1 rather than the T
2 phenotype. Moreover, IL-12 is also important in resistance to viral disease and has significant antitumor activity. It has been shown that single chain fusion proteins of naturally occurring heterodimeric cytokines such as IL-12 or IL-23 are bioactive

in vivo

Quality description

cytokines are suitable for a wide variety of cell culture applications. They are sterile-filtered prior to lyophilization. Generally, endotoxin levels are <0.1 ng/μg (<1 EU/μg), and purities are >95%. The biological activity is tested in appropriate bioassays.
