An efficient method for the isolation, purification, and renaturation
of human recombinant gamma-interferon from biomass of transformed E. c
oil cells was developed. It involves the extraction of the protein fro
m the inclusion bodies, preliminary purification of the protein, and t
hree stages of ion-exchange chromatography with an intermediate renatu
ration between the second and the third stages. A highly active (2 x 1
0(7) U/mg) recombinant protein of up to 99% purity (according to SDS-P
AGE and HPLC) was obtained with a 30% overall yield.
