摘要: 以二溴菊酸和3-[(4-硝基苯)氧基]苯甲醛为原料经4步反应合成了溴氰菊酯半抗原1-氰基[3-(4-氨基苯)苯基]甲基-2,2-二甲基3-(2,2-二溴乙烯基)环丙烷羧酸酯;用重氮化法将溴氰菊酯半抗原分别与牛血清白蛋白(BSA)和卵清白蛋白(OVA)相偶联制备免疫抗原和包被抗原,紫外吸收法估算偶联比分别为11:1和8:1;以BSA偶联物作免疫抗原免疫日本大耳白兔制备溴氰菊酯多克隆抗体,间接非竞争ELISA法测定2个抗血清效价分别为100000和80000,间接竞争ELISA法初步测定农药浓度50μg/ml时抑制率达到80%以上,为研究建立溴氰菊酯农残免疫快速测定方法奠定了基础。

Abstract: The hapten of deltamethrin was synthesized by chemistry method, the results of the 1H-NMR indicated that the hapten was synthesized successfully. Hapten was conjugated to bovine serum albumin (BSA) and ovalbumin (OVA) by diazotization method, two artificial antigens were used as antigen and coating antigen. Antigens were confirmed by ultraviolet spectrum. The coupling ratio were 11:1 and 8:1.Two rabbits were immunized, the antiserum was examined by indirect ELISA and indirect competitive ELISA experiments, the titer of the two rabbits was 100000 and 80000 separately, the inhibition ratio was more than 80% when the concentration of the deltamethrin was 50μg/ml. The results showed that the artificial antigen was synthesized successfully.
