Polypeptide for detecting Seneca virus antibody and application of polypeptide

The invention discloses a polypeptide for detecting a Seneca virus antibody and application of the polypeptide. The polypeptide is composed of an eVP1-1 and an eVP2-1. The eVP1-1 is a polypeptide of P11 or P12: P11, wherein the P11 is a polypeptide of which the amino acid sequence is SEQ ID No. 1, and the P12 is a polypeptide of which the amino acid sequence is the 2-16th site of SEQ ID No. 1; theeVP2-1 is a polypeptide of P21 or P22, wherein the P21 is a polypeptide of which the amino acid sequence is SEQ ID No.2, and the P22 is a polypeptide of which the amino acid sequence is the 2-15th site of SEQ ID No.2. The antibody detection kit prepared from the polypeptide is high in sensitivity, high in accuracy, simple and rapid to operate, and suitable for rapid and large-scale screening anddetection of Seneca virus infected serum antibodies by veterinary departments and entry and exit inspection and epidemic prevention bureaus at all levels of grassroots. 本发明公开了检测塞内卡病毒抗体的多肽及其应用。该多肽由eVP1-1和eVP2-1组成；所述eVP1-1是P11或P
