The ratio of hapten and bovine serum albumin in an antigenconjugate was determined by matrix-assisted laserdesorption/ionization time-of-flight mass spectrometry. Ahybridoma secreting monoclonal antibody against ginsenosideRg(1) was produced by fusing sprenocytes immunized with aginsenoside Rg(1)-bovine serum albumin conjugate withHAT-sensitive mouse myeloma cell line, P3-X63-Ag8-653. A very smallcross-reaction appeared with ginsenoside Re. The full measuringrange of the assay extends from 0.3 mug ml(-1) to 10 mug ml(-1) ofginsenoside Rg(1).
抗原缀合物中半抗原与牛血清白蛋白的比例通过基质辅助激光解吸/电离飞行时间质谱法确定。用人参皂苷 Rg(1)-牛血清白蛋白缀合物免疫的脾细胞与 HAT 敏感的小鼠骨髓瘤细胞系 P3-X63-Ag8-653 融合,产生了一株分泌针对人参皂苷 Rg(1)的单克隆抗体的杂交瘤。该方法与人参皂苷 Re 有很小的交叉反应。测定的全测量范围从 0.3 微克/毫升到 10 微克/毫升的人参皂苷 Rg(1)。
