摘要
GP4蛋白是猪繁殖与呼吸综合征病毒(Porcine reproductive and respiratory syndrome virus,PRRSV)的次要结构蛋白,在病毒的复制与侵染中起重要作用。通过合成GP4蛋白的重叠多肽,采用间接ELISA、dot-ELISA的方法对GP4蛋白的B细胞表位进行初步筛选,得到1个免疫显性肽段Ⅰ(50)SCLRHGDSSSPTIRKSS(67),并对其抗体水平进行测定,为PRRSV的抗体检测及其新型表位疫苗的研究奠定基础。
GP4 protein is a minor structural protein of Porcine Reproductive and Respiratory Syndrome Virus(PRRSV),but it plays an important role in virus replication and infection.In this study,the overlapping peptides of GP4 protein were synthesized.The B cell epitope of GP4 protein was screened by indirect ELISA and dot-ELISA to obtain an immunodominant peptideⅠ(50)SCLRHGDSSSPTIRKSS(67),and its antibody level was measured,which helped the detection of PRRSV and its novel epitope vaccine.
