【摘要】:近年来环介导等温扩增技术(Loop-Mediated Isothermal Amplification,LAMP)越来越多地应用于转基因农作物、微生物等的基因检测中。为了提高相关检测机构的转基因产品检测效率,加快进出口食品农产品的通关速度,本文首次使用碟式芯片环介导恒温扩增技术,在65℃恒温条件下,对样品中的P-Ca MV35S、T-NOS、NPTⅡ、BAR、PAT、Cry1Ac、EPSPS I、EPSPS II、FMV35S和GM-HRA等转基因靶标进行同步检测,检出限可达到0.5%(m/m),实现一次上样即可完成样品的转基因成分筛查。该方法特异性和灵敏度良好、检测时间较短,可实时读取扩增结果。对实际样品的检测结果表明,该方法的检测结果与实时荧光PCR方法的完全一致。本文开发的转基因检测微流控恒温扩增碟式芯片,可用于常见农产品(大豆、玉米、大米和棉花等)的转基因成分筛查,为转基因产品的定性检测提供了新的快速、灵敏、高通量技术平台。
