| 摘 要： | 目的获得稳定、高效分泌抗氯霉素单克隆抗体的杂交瘤细胞株。方法以CAP-HS-BSA免疫BALB/c小鼠,用细胞融合技术筛选抗氯霉素单克隆抗体杂交瘤细胞,体内诱生腹水法大量制备单抗。捕获ELISA法测定小鼠免疫球蛋白亚型,间接ELISA法测定腹水效价;用两步硫酸铵法和G蛋白亲和层析法来纯化腹水。结果成功建立了一株分泌抗CAP单克隆抗体（McAb）的杂交瘤细胞4D10。经检测,其分泌的抗体亚类为IgG1,杂交瘤染色体数目90-110条,间接ELISA检测诱生小鼠腹水的抗体效价达1∶2.56×105,纯度达95%,该细胞连续培养生物学性状稳定。结论成功制备的抗氯霉素单克隆抗体4D10效价高、纯度高,为利用该单抗研制检测氯霉素残留试剂盒提供原材料。
