文摘The recombinant GBV-C/HGV NS3 protein was expressed in Sf9 insect cells and analyzed by SDS-PAGE. A protein band about Mr 43810 was demonstrated on polyacrylamide gel electrophoresis and this protein amounted to more than 30% of the total cell proteins. Recombinant NS3 protein was purified by Ni-NTA column. Western blot showed that this recombinant protein could react with GBV-C/HGV RNA positive mixed sera. The recombinant GBV-C/HGV NS3 protein could be used to detect GBV-C/HGV infection and will supply material for study of structure and function of this protein.
