Recombinant Human IL-12 p70 (CHO derived)

Product Details

Catalog Number: 200-12
Description:

IL-12 is a potent regulator of cell-mediated immune responses and it induces IFN-γ production by NK and T cells.  It is produced by activated monocytes/macrophage cells, B lymphocytes and connective tissue-type mast cells.  Among its biological activities, IL-12 promotes the growth and activity of activated NK, CD4+ and CD8+ cells, and induces the development of IFN-γ-producing Th1 cells.  Recombinant Human IL-12 is a 75.0 kDa heterodimeric glycoprotein consisting of disulfide-linked 35 kDa (p35) and 40 kDa (p40) subunits (503 total amino acid residues).

Purity: ≥ 98% by SDS-PAGE gel and HPLC analyses.

Biological Activity: Assay #1: Determined by its ability to induce IFN-γ production from NK cells co-stimulated with IL-18. The expected ED50 is ≤ 1.0 ng/ml, corresponding to a specific activity of ≥ 1 x 106 units/mg.

Assay #2: Determined by its ability to increase IFN-γ production by anti-TCR mAb-stimulated PBMCs. The expected ED50 for this effect is 4.0-8.0 ng/ml.

Calculated Molecular Weight: 75 kDa

Accession Number: p35: P29459 p40: P29460

Gene ID: p35: 3592 p40: 3593
