Inhibition of HCV-LP binding by purified human anti-HCV IgG. (A) Inhibition of cellular HCV-LP binding by anti-HCV-positive or control serum (dilution, 1:25). (B) Inhibition of cellular HCV-LP binding by purified anti-HCV or control IgG (1 mg/ml) from the same sera shown in panel A. (C) Concentration-dependent inhibition of HCV-LP binding by purified anti-HCV IgG (squares) and serum containing anti-HCV antibodies (circles). Analysis of inhibition of HCV-LP binding was performed as described in the legend to Fig. 2. Serum IgG concentrations were determined as described in Materials and Methods.
