NOVEL INTERFERON ALPHAS

摘要

Novel IFN alpha S51B10 and IFN alpha S17H9 of this invention are prepared from BALL-1 cell induced with Sendai virus according to the well known recombinant DNA technique. Further, this invention relates to a DNA encoding interferon alpha S51B10 or alpha S17H9, a recombinant plasmid enabling an expression of interferon alpha S51B10 or alpha S17H9 in a host microorganism and a microorganism transformed by the recombinant plasmid. These two IFN alpha s have antiviral and anti-tumor activity as other subtypes of IFN alpha and are useful as medicines for human and animal.
