摘要: 本研究采用马绒毛膜促性腺激素(equine chorionic gonadotropin,eCG)纯品免疫BALB/c小鼠,取其脾细胞与同系小鼠骨髓瘤细胞SP2/0按1∶10融合,间接酶联免疫吸附法(ELISA)筛选阳性克隆和有限稀释法克隆,扩大培养后于小鼠腹腔制备腹水,共得到8株能稳定分泌单克隆抗体的杂交瘤细胞株,采用间接ELISA测定抗体效价,效价均达10-5以上。用获得的杂交瘤细胞株制备单克隆抗体,为eCG分泌水平的ELISA检测方法的建立确立了条件。

Abstract: This study fusing the spleen cells of BALB/c mice which was immunized with high purified equine chorionic gonadotropin and myeloma cells SP2/0 at the rate of 1∶10, and screening the positive cloning by the means of indirect enzyme linked immunosorbent assay. Positive cells were clone through limited dilution method, injecting the mixture into the abdominal cavity of mice after intermediate cultured. Antibody titer was assayed by ways of indirect ELISA. Eight hybridoma cell lines were obtained which could secrete eCG stably, titer reached above 10-5. The obtained eCG hybridoma cell lines, which laid a foundation to assay the level of eCG.

Key words: equine chorionic gonadotropin; hybridoma cell line; monoclonal antibody; enzyme linked immunesorbent assay
