猪的繁殖、呼吸的症候群被 PRRS 病毒(PRRSV ) 引起,它有六结构的蛋白质(GP2, GP3, GP4, GP5, M 和 N ) 。GP5 和 N 蛋白质是为由连接酶的 immunosorbent 试金(ELISA ) 和另外的方法的血清学的察觉的重要目标。向这个目标,我们与 recombinant GP5 抗原开发了间接 ELISA,这个方法被比较验证到 LSI PRRSV-Ab ELISA 工具包。结果显示涂的 recombinant 抗原的最佳的集中是为 1:40 的浆液冲淡的 0.2 g/well。对 LSI PRRSV-Ab 工具包的同意的率是 88.7%(266/300 ) 。这些结果作为抗原支持 recombinant GP5 的潜在的使用让间接 ELISA 在猪检测 PRRSV 抗体。
Porcine reproductive and respiratory syndrome is caused by the PRRS virus (PRRSV),which has six structural proteins (GP2,GP3,GP4,GP5,M and N). GP5 and N protein are important targets for serological detection by enzyme-linked immunosorbent assay (ELISA) and other methods. Toward this goal,we developed an indirect ELISA with recombinant GP5 antigens and this method was validated by comparison to the LSI PRRSV-Ab ELISA kit. The results indicated that the optimal concentration of coated recombinant antigen was 0.2 μg/well for a serum dilution of 1:40. The rate of agreement with the LSI PRRSV-Ab kit was 88.7% (266/300). These results support the potential use of recombinant GP5 as an antigen for indirect ELISA to detect PRRSV antibodies in pigs.
