摘要: 为研制一种用于检测牛奶中呕吐毒素(deoxynivalenol,DON)残留的快速检测试纸条,试验以人工合成抗原DON-OVA和羊抗鼠二抗为原料,包被硝酸纤维素膜;以抗DON单克隆抗体为原料,制备金标抗体,并冻干保存于反应板微孔中,最终制备出可用于检测牛奶中DON残留的胶体金快速检测试纸条。结果显示,该检测试纸条检测限为100 μg/L,重复性、特异性均较好,可用于检测牛奶中DON残留。

Abstract: For development of a rapid test strip for detecting vomitoxin (DON) residue in milk.We used DON-OVA and secondary antibody goat anti-mouse to coat nitrocellulose membrane,and used anti-DON monoclonal antibody to prepare colloidal gold labeled antibody,then lyophilized in micro-holes of reaction plate.At last we prepared a rapid test strip that could be used for detecting DON residue in milk.The results showed that the limit of detection of the test strip was 100 μg/L,and the repeatability and the specificity were preferably,so the rapid strip could be used for detecting DON residue in milk.
