摘  要:
根据外源基因草丁膦乙酰转移酶基因(PAT)与载体骨架连接区序列设计引物,建立了基于重组酶聚合酶扩增技术(RPA)的转基因玉米Bt11特异性快速检测方法。结果表明:该方法可在37℃条件下20 min内完成转基因玉米Bt11的检测,绝对检测限为100拷贝/μL,相对检测限为0.1%。

摘  要:
The primers was designed according to the junction sequence of exogenous gene phosphinothricin acetyltransferase gene( PAT) and vector backbone, and a specific rapid detection method based on recombinase polymerase amplification( RPA) for genetically modified maize Bt11( GM Bt11) was established. The results showed that the method could be used to detect genetically modified maize( Bt11) in 20 min under 37 ℃. The absolute detection limit was 100 copies/μL,and the relative detection limit was 0. 1%.
