Objective To study on the biological characteristic of recombinant E. coll strain expressing human interferon a2b, and ensure the stable quality of the expressed product. . Methods The biological characteristic of recombinant E. coli strain were detected by microbiological, molecular biological and immuno-logical methods. . Results The recombinant E. coli strain is of typical, morphologically, and the biological characteristics of it showed no significant change after being stored in glycerol for one year, or in a freeze-dried form for 2 years. Conclusion The biological characteristics of recombinant E. coli strain are stable.
