抗人类免疫缺陷病毒gp41和丙型肝为病毒NS3杂交？…

目的 为检测血清中人类免疫缺陷病毒和丙型肝炎病毒抗原提供血清学指标。方法 用纯化的重组ＨＩＶ和ＨＣＶ抗原蛋白作为联合免疫原，免疫ＢＡＬＢ／ｃ小鼠，取脾细胞与Ｓ２／０小鼠骨髓瘤细胞融合，并采用挑单个细胞的方法进行一次克隆。结果 分别获得４株和６株能稳定分泌高效价抗ＨＩＶ和ＨＣＶ抗的蛋白单克隆抗体杂交瘤细胞株。

Establishment of hybridomas secreting monoclonal antibodies to HIV-gp41 and HCV-NS3]

OBJECTIVE: To establish the monoclonal antibodies of HIV and HCV for developing serological diagnostic method. METHODS: The antigens of HIV gp41 and HCV NS3 expressed from bacteria were mixed to immunize BALB/c mice. The hybridoma cell lines were obtained by fusing SP2/0 myeloma cells with spleen cells from immunized mice. RESULTS: Four hybridoma cell lines secreting specific antibodies against gp41 of HIV and six hybridoma cell lines secreting antibodies to NS3 of HCV were obtained. ELISA sandwich method for detection of viral antigens with McAbs was developed. CONCLUSION: A quick and convenient method for obtaining McAbs was developed using mixture of different antigens for immunizition of mice. The monoclonal antibodies had high senusitivity and were stably secreted by hybridoma cell lines. This technique is worthy to be popularized.
