摘要: 以盐酸克伦特罗(clenbuterolhydrochloride)重氮化后分别连接到牛血清蛋白(BSA)和卵清蛋白(OVA)上制得免疫原BSA-CL和包被抗原OVA-CL。通过免疫兔获得含有多克隆抗体的血清,经硫酸铵沉淀、纯化,得到兔源抗CL的抗体,在此基础上建立了间接酶联免疫检测方法。实验结果表明,抗CL抗体最适稀释度为1:1000,羊抗兔酶联抗体(HRP-IgG)的最适稀释度为1:1500。该检测方法的检测灵敏度为1.452μg/L,线性检测范围为7.26~90.75μg/L。

Abstract: Hapten clenbuterol was conjugated with Bovine Sera Albumin (BSA) and Ovalbumin(OVA) by diazotization to produce immunogen BSA-CL and OVA-CL used for immunizing rabbit. The rabbit antiserum was purified with ammonium sulfate fractionation to prepare polyclonal antibody against clenbuterol. An indirect enzyme-linked immunosorbent assay (ELISA) was developed to detect and quantitate clenbuterol. The sensitivity of the assay is 1.452μg/L, and the standard curve is linear from 7.26 to 90.75μg/L.

Key words: clenbuterol hydrochloride, enzyme-linked immunosorbent assay, method validation
