摘  要:
由毒死蜱与3-巯基丙酸在碱性条件下反应,合成了毒死蜱半抗原。然后通过碳二亚胺法将毒死蜱半抗原分别与牛血清白蛋白(BSA)和鸡卵清白蛋白(OVA)共价偶联,得到了免疫抗原和包被抗原。用免疫抗原免疫兔子获得了高效价的多克隆抗体,抗血清效价达到了1:160000。通过试验确立了毒死蜱标准曲线,检测限为0.5μg.L-1,抑制中浓度I50为18.2μg.L-1,检测线性范围为1.8~1000μg.L-1。

摘  要:
This study reported that the hapten of chlorpyrifos was synthesized by using chlorpyrifos reacted with 3-marcapropanoic acid.The hapten was conjugated to bovine serum albumin(BSA) and ovalbumin(OVA) with the dicyclohexylcarbodimide method to form artificial immune antigen and coating antigen.The anti-chlorpyrifos polyclonal antibodies with high titer were obtained by using the artificial immune antigen to immune in the rabbits,and the titer is 1:160 000 for antiserum.The standard curves are confirmed by experiments,the real detection limit of the ELISA was 0.5 μg.L-1 with an I50 value of 18.2 μg.L-1 and the linear ranging from 1.8 to 1 000 μg.L-1.
