抗人肝微粒体蛋白单克隆抗体细胞系的建立及鉴定

目的 初步建立抗人肝微粒体蛋白单克隆抗体规模化制备技术平台,为制备抗人细胞色素P450(CYP450)亚型蛋白的单克隆抗体奠定基础.方法 按常规方法进行细胞融合,以酶联免疫吸附测定法(ELISA)筛选杂交瘤,以ELISA、免疫组化(IH)、免疫印迹(Western Blot)、免疫沉淀(IP)对单克隆抗体加以鉴定.结果 融合后筛出杂交瘤,其分泌抗体类型为IgG1、IgG2a、IgG2b及IgM.免疫组化(IH)图片上,人肝细胞浆内均可见阳性颗粒.免疫沉淀(IP)和免疫印迹(WesternBlot)结果显示,所制备抗体与人肝微粒体蛋白有特异性结合.结论 筛选制备的单克隆抗体杂交瘤能分泌特异性较强的抗人肝微粒体蛋白单克隆抗体.

Cell line establish and indentify of monoclonal antibody against human liver microsome proteins

Objective Cell Line Establish and indentify of Monoclonal Antibody Against Human Liver Microsome ProteinsMethods Mice were immunized with human liver microsome proteins.Myeloma cells were fused with the PEG4000.Monoclonal hybridomas were screened by enzyme-linked immunosorbent assay(ELISA),and were identified by ELISA,immunohistochemistry(IH),Western Blot and Immunoprecipitation(IP).Results Mice were immunized with human liver microsome proteins.Myeloma cells were fused with the PEG4000.Monoclonal hybridomas were screened by enzyme-linked immunosorbent assay(ELISA),and were identified by ELISA,immunohistochemistry(IH),Western Blot and Immunoprecipitation(IP).Conclusion Mice were immunized with human liver microsome proteins.Myeloma cells were fused with the PEG4000.Monoclonal hybridomas were screened by enzyme-linked immunosorbent assay(ELISA),and were identified by ELISA,immunohistochemistry(IH),Western Blot and Immunoprecipitation(IP).
