摘    要:为制备抗猪瘟病毒(CSFV)单克隆抗体(MAb),本实验以表达CSFV E2囊膜糖蛋白的水泡口炎假病毒免疫BALB/c小鼠,取其脾细胞与骨髓瘤细胞SP2/0进行融合;利用间接ELISA方法和携带荧光素酶(Luciferase)报告基因的HIV-luc/CSFV-E1E2假病毒系统筛选分泌中和性E2MAb的杂交瘤细胞;测定MAb亚型并纯化后,间接ELISA方法测定MAb的效价;采用western blot鉴定MAb的特异性亲和力;利用HIV-luc/CSFV-E1E2假病毒进行体外中和试验,分析MAb抑制病毒感染的能力。结果表明本实验获得了1株分泌中和性MAb的杂交瘤细胞9C8,该MAb能与E2蛋白特异性结合,而且体外抑制试验中和效价大于1∶25600。

关 键 词:猪瘟病毒  中和性单克隆抗体  假病毒  中和试验

Abstract:To prepare E2 neutralizing monoclonal antibody(MAb) against classical swine fever virus(CSFV) ,BALB/c mice were immunized with recombinant vesicular stomatitis virus(rVSV) expressing the envelope glycoprotein E2 of CSFV;mouse splenic cells were fused with SP2/0 cells and hybridoma cells were screened by indirect ELISA and retroviral pseudotype virus HIV-luc/CSFV bearing CSFV E1 and E2 glycoproteins. The specificity and the antigen-binding activity of the MAb were identified by indirect ELISA and western blo...
Keywords:CSFV  neutralizing monocolonal antibody  pseudotyped virus  neutralization assay
