Background
IFN-ω is a type I interferon that can be induced by virus-infected leukocytes. Members of the type I interferon family, which includes IFN-α, IFN-β, and IFN-ω, signal through the IFNAR-1/IFNAR-2 receptor complex, and exert antiviral and antiproliferative activities. Mire-Sluis et al have described bioassays for IFN-α, IFN-β, and IFN-ω that exploit the ability of these factors to inhibit proliferation of TF-1 cells induced by GM-CSF. The bioassays can be used also with EPO and TF-1 cells, or EPO and EPO-transfected UT-7 cells; IFN-ω exhibits about 75% sequence homology with IFN-α, and contains two conserved disulfide bonds that are necessary for full biological activity. Recombinant Human IFN-ω is a 19.9kDa protein consisting of 172 amino acid residues.
