摘要: 旨为预测类猪圆环病毒因子P1 VP2蛋白的B细胞表位。采用生物信息软件和互联网服务器,预测VP2的二级结构,分析VP2表面特性(亲水性、可塑性、可及性和抗原性),综合预测VP2的B细胞抗原表位。结果表明,P1VP2蛋白肽链的6-18和80-92区段为预测的B细胞表位优势区。多参数方案综合预测P1 VP2蛋白的B细胞抗原表位,为进一步鉴定表位及设计疫苗奠定了基础。

关键词: P1, 二级结构, B细胞表位, 生物信息学, 预测

Abstract: To predict the B cell epitopes for VP2 protein of porcine circovirus2like agent P1.By using biotic softwares and network servers,the secondary structure of VP2 was predicted,and the surface properties (hydrophilicity,flexibility,accessibility and antigenicity) of VP2 were analysed.Then the B cell epitopes integrated prediction were obtained.The predominant B cell epitopes predicted were probably in the region of 6-18 and 80-92.The results of B cell epitopes prediction using multiple parameters are helpful for further epitopes identification and vaccine design of P1.
