2.2 Antigenicity and hydrophilicity analyses of NTD of G1 and G2
PEDV S protein
Antigenicity and hydrophilicity analyses based on the amino acid
sequence from 1 to 380 at N-terminal of S proteins of PEDV Chinese
variant and CV777 vaccine strain were carried out by using Protean
software of DNAStar Lasergene (DNAStar, Inc., Madison, WI). Antigenic
indexes of the N-terminal domains (NTD) were calculated under the
Jameson-Wolf method, and hydrophilicity plots were constructed by
Kyte-Doolittle method, respectively.
