FIG. 1.

Antigenic reactivity of overlapping synthetic 30-, 25-, and 18-mer peptides with anti-HEV IgG antibodies. (A) Approximate locations of six antigenic domains. (B) Vertical bars show the location of the N-terminal amino acid of each synthesized peptide. (C, F, and J) Charts demonstrating the number of serum specimens that are immunoreactive with each peptide. (D, G, and K) Charts showing the average P/N ratio (see Materials and Methods) calculated for all serum specimens that are immunoreactive with each synthetic peptide.
