| 摘 要： | 用纯化的重组HIS标签N蛋白免疫BALB／c小鼠，采用杂交瘤技术制备抗PRRSVN蛋白的单克隆抗体（McAb），经细胞融合获得5株可分泌特异性McAb的抗PRRSVN蛋白的杂交瘤细胞1A12，3F11，5A3，5F9，4E4。其中1A12，3F11，5A3，4E4杂交瘤上清与HIS-蛋白与GST—N蛋白两种抗原包被的ELIA反应均为阳性。5F9与HIS—N蛋白包被的ELISA反应为阳性，而与GST—N蛋白包被的ELISA反应呈阴性。单抗1A12，3F11，4E4，5A3与HIS-N与GST—N蛋白的Western blotting反应均为阳性，而5F9只与HIS-N反应。IFA检测显示1A12，3F11，5A3，4E4株单抗都有明显的荧光，说明其与PRRSV呈阳性反应。同时，ELISA检测又有很好的特异性。

| Abstract: | After the immunization of BALB/c mice with recombinant HIS-N protein, the stimulated splenocytes were fused with SP2/0 myelomas to produce hybridomas. 5 hybridoma lines of monoclonal antibody against N protein of PRRSV have been developed, designated as 1A12,3Fll, 5A3,5F9,4E4. The results of IFA showed the McAbs could react with PRRSV in MARC-145 cells. The results of western- blotting indicated that all the McAbs were against the lined epitopes in HIS-N protein and GST-N protein of PRRSV except 5A3 and 5F9 which only reacted with HIS-N protein. The IFA showed the 1A12,3Fll, 5A3,4E4 reacted with cells infceted by PRRSV positively and the ELISA showed no reaction with antiserum to pseudorabies virus, Japanese epidemic encephalitis virus B, porcine circovurus virus, foot and mouth disease virus. |
