Neutralization activity and kinetics of two broad-range human monoclonal IgG1 derived from recombinant Fab fragments and directed against Hepatitis C virus E2 glycoprotein.

ABSTRACT

Hepatitis C virus (HCV) is the major cause of chronic liver disease worldwide. There is evidence that neutralizing anti-HCV antibodies may find potential applications in novel prophylactic and therapeutic strategies. This paper describes the very high neutralization activity and unique biological features of two broadly cross-reactive and cross-neutralizing anti-HCV human monoclonal IgG1 derived from human monoclonal recombinant Fab fragments.
