Recombinant Mouse IL-12 Protein Summary
A full-length protein corresponding to IL12A.
Method
Insect cells infected with baculovirus: mouse p40, amino acids met 1-ser 335, (accession # NM_008352) was co-expressed with mouse p35, amino acids met 1-ala 215, (accession # NM_008351).
This protein has been tested in bioassay for induction of IFN-gamma; production, yielding an ED50 of less than 0.3 ng/ml, corresponding to a specific activity of approximately 3.0×10^6 Units/mg.

Background
Interleukin-12 (IL-12) is a heterodimeric 70 kD (p70) cytokine composed of two covalently linked, glycosylated chains, 40kD (p40) and 35-kD (p35). IL-12 is mainly produced by monocytes, macrophages, and dendritic cells in response to bacterial products such as lipopolysaccharides (LPS), to intracellular pathogens or upon interaction with activated T cells. IL-12 was originally discovered because of its ability to induce interferon-gamma (IFN-g) production, cell proliferation, and cytotoxicity mediated by natural killer cells and T cells. It is now established that IL-12 also plays a key role in the development of Th1 responses, leading to IFN-g and IL-2 production. These cytokines can in turn promote T-cell responses and macrophage activation. sciences recombinant mouse IL-12 p70 is produced in baculovirus-infected insect cells as an authentic heterodimer of precursor p35 and p40 subunits using a dual promoter expression system. It is distinct from other available forms of the protein in that it is expressed as a true heterodimer, as opposed to a single-chain, pseudo-heterodimer in which the subunits are joined by an artificial linker.
