Interferon omega, Recombinant, Human (IFN alpha II-1, IFNW1, IFN omega)

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-alpha, IFN-beta, and IFN-omega, signal through IFNAR-1/IFNAR-2 receptor complex, and exert antiviral and antiproliferative activities.IFN-omega exhibits about 75% sequence homology with IFN-alpha, and contains two conserved disulfide bonds, which are necessary for full biological activity. Recombinant Human IFN-omega is a 19.9kD protein consisting of 172 amino acid residues.\n\nBiological Activity:\nThe ED50 was determined by a cytotoxicity assay using Human TF-1 cells is ~0.01ng/ml, corresponding to a specific activity of ~1x10e8 units/mg.\n\nAA Sequence:\nCDLPQNHGL LSRNTLVLLH QMRRISPFLC LKDRRDFRFP QEMVKGSQLQ KAHVMSVLHE MLQQIFSLFH TERSSAAWNM TLLDQLHTGL HQQLQHLETC LLQVVGEGES AGAISSPALT LRRYFQGIRV YLKEKKYSDC AWEVVRMEIM KSLFLSTNMQ ERLRSKDRDL GSS\n\nQuality Control:\nVerified by N-terminal and Mass Spectrometry analyses (when applicable).\n\nEndotoxin:\n<0.1ng/ug of protein (<1EU/ug).\n\nProtein Content:\nVerified by UV Spectroscopy and/or SDS-PAGE gel.\n\nStorage and Stability:\nStore lyophilized products at -20 degrees C. For reconstituted solutions of most products, we recommend short-term storage at 4 degrees C. For longer term storage the protein solution should be stored with a carrier protein (eg. 0.1% BSA) in working aliquots and stored frozen at -20 degrees C. Additional freeze/thaw cycles may cause some denaturation of the protein.
