摘要:
目的 转化体特异性检测是转基因生物安全监管中识别转化体合法性的重要技术手段,目前转化体特异性检测以实验室检测为主,急需开发能够现场快速检测的方法,满足转基因生物安全监管需求。 方法 以抗虫耐除草剂转基因玉米DBN9501为材料,利用环介导等温扩增(loop-mediated isothermal amplification, LAMP)技术结合CRISPR/Cas12a(clustered regularly interspaced short palindromic repeats,CRISPR)技术(LAMP-CRISPR/Cas12a),辅助试纸条显示,开发转化体特异性快速检测方法。 结果 本方法具有检测特异性,检出限为20拷贝,转化体含量为0.1%,检测时间<60 min。 结论 LAMP-CRISPR/Cas技术能够实现快速检测转基因玉米DBN9501转化体特异性,该方法将为转基因生物安全监管快速检测技术研究提供重要技术支撑。
