Recombinant human IFN-omega protein
IFN-omega, also known as interferon-omega, is a member of a family of proteins with antiviral, growth inhibitory and immunomodulatory activity. Type I IFNs consist of IFN alpha, beta, tau, and omega and bind to the type I IFN receptor, whereas IFN-gamma is the only type II IFN and is specific for the type II IFN receptor. IFN-omega is produced primarily in leukocytes in response to viral infection, and it has biological activities. Also, it was reported that IFN-omega could inhibit the growth of human tumors in vivo. Recombinant human IFN-omega, fused to His-tag at C-terminus, was expressed in HEK293 cell and purified by using conventional chromatography techniques.
