Interleukin-10 (IL-10), originally known as Cytokine Synthesis Inhibitory Factor (CSIF) shares over 80% sequence homology with the Epstein-Barr Virus protein BCRFI. The reported biological activities of IL-10, which may be interrelated, include inhibition of macrophage-mediated cytokine synthesis, suppression of the delayed type hypersensitivity response, and stimulation of the TH2 cell response, which results in elevated antibody production. The net effect of IL-10 action appears to be the inhibition of pro-inflammatory T cell mediated immunity. Mouse IL-10 is an 18.8 kD protein containing 160 amino acid residues.  Recombinant mouse IL-10 (Cat. No. 550070) is supplied as a frozen liquid comprised of 0.22 µm sterile-filtered aqueous buffered solution, glycerol and bovine serum albumin, with no preservatives.  Recombinant mouse IL-10 is ≥ 95% pure as determined by SDS-PAGE, and an absorbance assay based on the Beers-Lambert law.  The endotoxin level is ≤ 0.1 ng/µg of mouse IL-10, as measured in a chromogenic LAL assay.
