A putative core protein derived from hepatitis C virus was expressed in E. coli. More than 5% of the total protein expressed in the bacteria after induction by isopropylthio-beta-D-galactoside was shown to be the expected protein. Western blotting with this E. coli lysate proved to be more efficient than ELISA with a non-structural viral protein, C100, to detect infection of hepatitis C virus in the sera of patients with non-A, non-B chronic hepatitis, hepatocellular carcinoma as well as in sera from healthy persons.
