Abstract: Multimer peptides (e.g. 30- to 45-mer peptides) derived from hepatitis C virus envelope proteins reacting with the majority of anti-HCV antibodies present in patient sera are described. The usage of the latter peptides to diagnose, and to vaccinate against, an infection with hepatitis C virus is also disclosed.
Abstract: Antibodies to two new epitopes on the HCV envelope proteins were identified which allow routine detection of native HCV envelope antigens, in tissue or cells derived from the host. The new epitopes are: the E1 region aa 307-326 and the N-terminal hyper variable region of E2 aa 395-415. Surprisingly, we characterised an antibody that reacts with various sequences of the hypervariable domain of E2. Specific monoclonal antibodies directed against these epitopes and allowing routine detection of viral antigen are described.
