Extra Details:: IFN-omega is a type I interferon, which can be induced by virus-infected leukocytes. Members of the type I interferon family, which includes IFN-a, IFN-B, and IFN-w, signal through IFNAR-1/IFNAR-2 receptor complex, and exert anti-viral and anti-proliferative activities. IFN-omega exhibits about 75% sequence homology with IFN-a, and contains two conserved disulfide bonds, which are necessary for full biological activity. Recombinant Human IFN-omega is a 19.9kD protein consisting of 172aa. Source: Recombinant protein corresponding to human IFN-omega, expressed in E.coli. Biological Activity: Determined by a cytotoxicity assay using Human TF-1 cells. The ED50 was found to be 0.01ng/ml.
