title: [Antigenic activity of delta-antigen peptides corresponding to three genotypes of the delta hepatitis virus].
abstract: Six synthetic peptides from immunodominant region 65-80 aa derived from the sequences of delta-antigen corresponding to 3 HDV genotypes were obtained. Their antigenic activities were assessed by indirect enzyme immunoassay with sera of patients with hepatitis D and of asymptomatic carriers of anti-delta antibodies. Differences in antigenic characteristics of full-size 65-80 and truncated 71-80 aa peptides corresponding to three HDV genotypes were revealed. The diagnostic significance of synthetic 65-80 aa fragments is shown.
