| 摘 要： | 为制备并鉴定番茄溃疡病菌(Clavibacter michiganensis subsp.michiganensis,Cmm)的单克隆抗体(McAbs),用全菌皮下免疫BALB/C小鼠,采用B细胞杂交瘤技术,经免疫、融合、间接ELISA筛选和克隆等,获得稳定分泌抗体的阳性杂交瘤细胞株,得到了抗番茄溃疡病菌的单克隆抗体。经免疫后获得3株单抗分别为1A4、1C3和1B7,经亚类鉴定分别是IgM、IgG1、IgG1;纯化腹水间接ELISA效价分别为1:3.2×106、1:8.1×105、1:3.2×106;与其他同属不同亚种无交叉反应。结果表明:3株单克隆抗体均具有较高特异性和敏感性,可作为番茄溃疡病菌的检测抗体,其中,1A4的效果最好。番茄溃疡病菌单克隆抗体的获得为进一步研发番茄溃疡病检测试剂盒奠定了基础。

| Abstract: | To prepare and identify monoclonal antibodies(McAbs) agains Bacterial canker of tomato,Cmm,BALB/C mice were immunized with Cmm hypodermically and McAbs were gained by hybridoma cell lines secreting McAbs were obtained using routine hybridoma technology and ELISA screening.Three hybridoma cell lines specific to Cmm were obtained after screening with indirect ELISA and subcloning.They were designated as 1A4,1C3 and 1B7.Identification of the subclass indicated that the monoclonal antibody secreted by 1A4 cell ... |
