Abstract:
A peptide-based enzyme immunoassay (PBEIA) has been developed using synthetic peptides whose sequences were selected from the core, envelope and non-structural regions of the prototype hepatitis C virus (HCV) genome. Results of PBEIA of sera obtained from several patients with various liver disorders were compared to those of commercial enzyme-linked immunosorbent assays (ELISA) and reverse transcription-polymerase chain reaction (RT-PCR). A large number of samples, which were repeatedly negative in commercial ELISA, were positive in PBEIA. There was a good correlation between the results of PBEIA and RT-PCR. The developed PBEIA proved to be a sensitive assay that had high specificity and was capable of detecting antibodies in various HCV-related liver disorders including the acute phase of the infection.
