Objectives To develop a new method for detecting the antibody corresponding to hypervariable region 1 (HVR1) in HCV infectious sera and explore the relation of anti HVR1 to viremia.
Objective To study the immunogenicity of multiple antigen peptide (MAP) corresponding to the hypervariable region 1(HVR1) within the putative envelope glycoprotein E2/NS1 of hepatitis C virus(HCV).
