Abstract

A method of screening a substance inhibiting the binding of hepatitis C virus E2/NS1 protein to an antibody having an affinity for the protein, which involves: (1) the step of bringing the hepatitis C virus E2/NS1 protein into contact with the above-described antibody in the presence and absence of a test substance; and (2) the step of comparing the binding of the hepatitis C virus E2/NS1 protein to the antibody in the presence and absence of a test substance. Thus, it becomes possible to provide novel drugs having antiviral effects of, for example, preventing infection with HCV.
