Expression in E. coli and purification of a chimeric p22-NS3 recombinant antigen of hepatitis C virus (HCV)

FEBS Lett. 1993 Jun 21;324(3):253-7. doi: 10.1016/0014-5793(93)80128-h.

Abstract

A recombinant antigen (p22-NS3), possessing putative HCV nucleocapsid protein (p22) and non-structural protein 3 (NS3) epitopes, was heavily expressed in E. coli and purified. The p22-NS3 purified recombinant antigen strongly reacts with sera containing human antibodies directed against p22 and NS3 providing a starting point for the design of an HCV single all-encompassing antigen for a blood screening assay.
