摘要 为了研究PCV2 Cap蛋白的检测方法,试验应用哈尔滨兽医研究所猪传染病研究室猪病分子诊断组已构建的基因工程重组菌NLS-Cap M15,经IPTG诱导表达获得原核表达Ⅱ型猪圆环病毒Cap蛋白,经亲和层析纯化后免疫6周龄Balb/c小鼠,取其脾细胞与SP2/0骨髓瘤细胞融合,经间接ELISA筛选获得了3株分泌Cap蛋白单克隆抗体的杂交瘤细胞,分别命名为2C3、2F3、1E10。结果表明:2C3、2F3均属于IgG1型,1E10属于IgG2a亚型,轻链都是κ链;经Western-blot检测,获得的3株单抗均可以特异性的识别Cap蛋白;ELISA检测其腹水效价均为1.0×105;间接免疫荧光检测单抗2C3、2F3、1E10反应均为阳性,表明这3株单抗能够识别PCV2病毒。
