LINEAR AND BRANCHED PEPTIDES EFFECTIVE IN DIAGNOSING AND DETECTING NON-A, NON-B HEPATITIS

摘要

The present invention relates to novel linear and branched peptides specific for the diagnosis and prevention of non-A, non-B hepatitis (NANBH), as well as hepatitis C virus (HCV) infection. More particularly, the present invention is directed to linear peptides diagnostic for NS-3 of HCV as well as branched synthetic substituted and hybrid peptides containing at least one epitope which is effective in detecting NANBH-associated antibodies in patients with NANBH using immunoassay techniques. In addition, this invention provides immunoassays for the detection and diagnosis of NANBH using the subject peptides, vaccine compositions for prevention and treatment of NANBH of HCV infection as well as a method of treating or preventing NANBH and HCV infection.
