Abstract

Recombinant human (rh) renin was expressed in Sf-9 insect cells. Baculovirus-infected Sf-9 cells produced active rh-renin in the late stage of cultivation. The rh-renin was purified after 5 d of culture by two steps of column chromatography. Approximately 0.61 mg of pure rh-renin was obtained from 200 ml of culture medium with a yield of 35.3%.
