摘要 目的:探讨杂交瘤细胞染色体形态、数目与抗体分泌能力及稳定性的关系。方法:对我室融合成功的10株杂交瘤细胞,采用秋水仙素法制备染色体,分别计数100个完整的中期分裂相细胞,并观察其形态。制备腹水和收集细胞培养上清液,间接ELISA法检测抗体效价。结果:经染色体计数与分析,10株杂交瘤细胞中,7株瘤株细胞间染色体形态一致,分散好,既有端着丝点染色体,也见中间着丝点染色体,染色体数目的标准差小于5.0,腹水和细胞培养上清抗体效价高,分泌稳定性好;3株染色体数差异大、标准差大的瘤株中,2株抗体效价低,分泌不稳定。结论:杂交瘤细胞染色体形态、数目与其分泌单克隆抗体的能力和稳定性有关,进行染色体分析有利于了解瘤株特性,可作为筛选高效、稳定瘤株的参考依据。
