摘要
【目的】建立转基因作物外源转基因成分环介导等温扩增技术检测方法。【方法】以转基因作物中常用的花椰菜花叶病毒35S启动子(CaMV35S)为主要研究对象,利用环介导等温扩增技术(loop-mediatedisothermal amplification,LAMP),针对CaMV35S基因的6个区域设计4种特异引物,利用1种链置换DNA聚合酶(Bst DNA polymerase)在65℃保温1h,通过荧光显色即可完成对转基因作物鉴定工作。同时对7种转基因作物进行LAMP检测。【结果】该LAMP方法通过特异性检测含有CaMV35S启动子的转基因作物,其检测结果的特异性与常规PCR方法结果一致,灵敏度是常规PCR的10倍。【结论】转基因作物LAMP检测方法具有高度的特异性及稳定性,结果可靠,非常适合转基因作物的快速检测,有较好的应用价值。
