The alignment assay based on amino acid sequence of N protein for PRRSV-1. The sequence alignment was performed using Clustal W method. A2-12, B25-30, C40-46, D51-67 and D80-90 represent known epitopes in N protein; E50-58, E64-72, E105-113 and E113-121 indicate four porcine T –cell epitopes. The insertion site of amino acid was indicated by triangle (). The highly conserved mutation sites in Chinese PRRSV-1 strains were marked with asterisk (*)
