[Production of purified human recombinant alpha2b-interferon]

Technology for producing biologically active recombinant alpha2b-interferon is based on creating a bacterial producer strain containing the cDNA of human interferon alpha. The authors have obtained two producers of recombinant alpha2b-interferon, the synthesis of the target protein in them occurs in the inclusion bodies. The schemes of isolation and purification of biologically active recombinant alpha2b-interferon have been developed. The drug purity was approximately 97-98%. Biological activity in the culture of sensory cells in the cytopathic test was 4.2*10(8)ME/mg.
