摘要

摘要: 目的制备红景天苷单克隆抗体，建立红景天苷间接竞争酶联免疫方法，实现经济、高效、简便快速批量检测红景天药材及其制品中的红景天苷含量，为其商品化检测试剂盒开发奠定基础。方法用已经成功偶联的红景天苷-BSA作为免疫原，免疫6~8周龄Balb/c小鼠，ELISA检测血清效价，取效价最高的小鼠脾细胞与骨髓瘤细胞进行融合，经有限稀释法筛选、克隆后获得能够稳定产生红景天苷单克隆抗体的细胞株，体内诱生腹水制备大量红景天苷单克隆抗体。利用该抗体，建立红景天苷间接竞争酶联免疫分析方法并进行方法学确认，包括日内精密度、日间精密度、回收率等指标。结果建立的间接竞争酶联免疫吸附分析方法的线性范围为4.07~598.45 ng·mL^-1，检测限IC₁₀为1.77 ng·mL^-1，半数抑制率IC₅₀为49.33 ng·mL^-1，日内精密度和日间精密度均小于4.5%，加标样品的平均回收率为94.3%，红景天苷含量检测结果与高效液相色谱法一致。结论本研究成功制备了红景天苷单克隆抗体，建立了间接竞争酶联免疫分析方法，能够用于为红景天苷含量的快速检测提供依据。

Abstract: Objective To prepare monoclonal antibody of salidroside for the development of an indirect competitive enzyme linked immunosorbent assay (ic-ELISA) methodology to accurately and rapidly detect salidroside in medicinal materials. Method Balb/c mice of 6-8 weeks old were immunized with the prepared salidroside-BSA. Specificity of the anti-serum was determined by ELISA. Spleen cells from the mice with positive result were fused with SP2/0 myeloma cells. Monoclonal hybridoma cells were screened by indirect ELISA with a limited dilution. Ascitic antibodies were induced and prepared from the positive cell line. Specific antibody against salidroside was used to establish ic-ELISA detection method that was verified by its specificity, precision and recovery rate on a known standard. Result The sensitivity of ic-ELISA was 49.33 ng·mL^-1 with a liner range of 4.07-598.45 ng·mL^-1. The detection limit of the method was 1.77 ng·mL^-1. The newly developed method detected salidroside in spiked samples with a recovery rate of 94.3% within the designed range. The relative standard deviation of the measurements was less than 4.5% on both intra- and inter-day assays. The determination by ic-ELISA agreed with that obtained by HPLC. Conclusion The newly established ic-ELISA method based on the salidroside monoclonal antibody was considered appropriate for the detection.
