摘要 用自主制备的莱克多巴胺特异性抗体建立了猪肉样品中莱克多巴胺药物残留的间接竞争酶联免疫检测方法,对该检测体系的灵敏度、准确度、精密度、特异性等性能进行了测定,并将该检测系统与高效液相色谱法(HPLC)进行了对比分析。结果显示:莱克多巴胺药物残留的酶联免疫检测体系的检测范围为1~100 ng,灵敏度为0.12 ng/mL,检测限为1 ng/mL,回收率为80%~100%,与同类药物如盐酸克仑特罗、硫酸特布他林及硫酸克仑特罗的交叉反应率均小于0.01%;采用HPLC方法进行莱克多巴胺药物残留的检测时,其检测范围为10~200μg/mL,检测限为1μg/mL,回收率为83%~100%。该方法与高效液相色谱法相比灵敏度较高,特异性强,检测结果准确度相近,但是在检测结果稳定性方面逊于HPLC方法。
