title: [Detection of antibodies to the nucleocapsid protein of Hepatitis C virus by immunoenzyme analysis using synthetic peptides of nucleocapsid N-terminal part].
abstract: Solid-phase synthesis of 7 linear peptides overlapping the immunodominant N-terminal region of hepatitis C virus (HCV) core protein (aa 7-75) was carried out. Their antigen reactivity was studied by non-competitive ELISA with sera from patients with chronic HCV infection. Three B-epitopes located within aa 7-19, 20-34, and 39-75 appeared to be the most immunoreactive. Use of the set of synthetic peptides in ELISA detected anti-HCV core antibodies with 93% efficiency in comparison with ELISA and commercial anti-HCV Recomblot based on the use of commercial recombinant HCV core protein.
