摘    要:目的:建立动物性食品中盐酸克伦特罗残留快速检测技术,确保食品安全.方法:以盐酸克伦特罗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.通过免疫得到多抗血清,经硫酸铵沉淀,Sephrose 4B-proteinA对抗体进行纯化,在此基础上建立间接竞争ELISA方法.结果表明:包被抗原的最适质量浓度为10 μg/mL,抗体的最佳稀释度为1∶1000;该方法的IC50为2.18 ng/mL,最低检测限达0.05 ng/mL,与沙丁胺醇和妥洛特罗的交叉反应率分别为8.28%和7.75%,平均加标回收率为90.78%.结论:该法灵敏度高,样品前处理简便、快速,适用于动物源性食品中盐酸克伦特罗残留的大批量现场检测.

Abstract:Objective:An indirect enzyme-linked immunosorbent assay(ELISA) was developed to detect Clenbuterol hydrochloride in animal foods in order to ensure food safety.Methed: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 hydrochloride.An indirect enzyme-linked immunosorbent assa...
Keywords:clenbuterol hydrochloride  enzyme-linked immunosorbent assay  method validation
