A RECOMBINANT HUMAN INTERFERONϖ, THE METHOD FOR EXPRESSING IT AND THE USES OF IT

摘要

A recombinant human interferon ϖ, the method for expressing it and the uses thereof are disclosed. The interferon ϖ is a protein having the amino acids residuals of SEQ ID NO: 2 in the sequence listing, or a protein derived from the protein of SEQ ID NO: 2 by substitution, deletion or addition of one or several amino acids in the amino acid sequence and having the same activity. The experiment studies demonstrated the interferon ϖ is safe for human body, and helpful for preventing SARS infection effectively. The method for expressing interferon ϖ has given higher yields, expressed and purified simply and conveniently, lower costs.
