From: Identification of E2 with improved secretion and immunogenicity against CSFV in piglets
Antigenicity analysis of E2s among different genetic groups. a The phylogenetic tree based on CFSV E2 genes was constructed, using the neighbor-joining method. E2ZJ was classified to subgroup 2.1. b Alignment of E2 proteins. Antigenic regions were highlighted: identified epitopes (red lines), predicted epitopes (blue lines) and identified conformational epitopes (green dots). Characteristic amino acids of E2ZJ were labeled with yellow boxes. Sequences were aligned using MegAlign
