摘要: |
目的 制备罗汉果甜苷V(MogV)特异性抗血清,建立MogV含量竞争性抑制酶联免疫检测法。方法 用罗汉果甜苷V-丁二酸酯-牛血清蛋白(MogV-HS-BSA)结合比约为44∶1为免疫抗原制备抗血清,用罗汉果甜苷V-丁二酸酯-人血清蛋白(MogV-HS-HSA)结合比约为64∶1为包被抗原,建立MogV含量竞争性抑制酶联免疫检测法。结果 包被抗原工作浓度为1 μg·mL-1,血清最佳稀释倍数为1∶8 000,在此工作浓度下,MogV浓度在1×10-4~1 μg·mL-1内回归方程Y=-0.158X+0.298,r=0.991 0。结论 成功制备了MogV抗血清,MogV 浓度在1×10-4~1 μg·mL-1内对抗血清的OD(405 nm)值抑制作用呈良好的线性关系。 |

Abstract: |
OBJECTIVE To prepare mogrosides V (MogV) specific antiserum and establish the competitive-inhibitive ELISA method to detect MogV content. METHODS Antiserum was prepared with the V-Mogrosides succinate-bovine serum albumin(MogV-HS-BSA) as the immunogen (ratio about 44∶1), the competitive inhibition ELISA method for MogV content was established with the V-Mogrosides succinate-human serum protein (MogV-HS-HSA) with a ratio of about 64∶1 as coating antigens. RESULTS The coating antigen working concentration was 1 μg·mL-1, the best serum dilution is 1∶8 000. Within MogV concentration 1×10-4-1 μg·mL-1, the regression equation was Y=-0.158X+0.298, r=0.991 0. CONCLUSION MogV anti-serum is successfully prepared. Within 1×10-4-1 μg·mL-1, the MogV concentration and OD value(405 nm) of the antiserum shows a good linear relationship. |
