【摘要】：重組酶聚合酶介導的等溫擴增(recombinase polymerase amplification,RPA)作為一種新型等溫擴增技術,具有反應時間短、靈敏度高、特異性強等特點,在轉(zhuǎn)基因檢測領域得到了廣泛關注。本研究針對轉(zhuǎn)基因玉米Bt11外源插入鏈接區(qū)域設計篩選了特異性引物和探針,建立了快速準確的熒光RPA檢測方法,在39℃條件下,20 min內(nèi)完成擴增并且能夠?qū)崟r監(jiān)測,可以準確有效地檢測到50個拷貝的靶標片段。而且,對于背景復雜的植物基因組DNA能夠得到準確的擴增曲線。本研究不僅可以滿足常規(guī)實驗室檢測,通過RPA便攜式儀器,還可以滿足轉(zhuǎn)基因植物現(xiàn)場檢測,具有廣闊的應用前景。
[Abstract]:As a new isothermal amplification technique, recombinant enzyme polymerase mediated isothermal amplification (recombinase polymerase amplification,RPA) has been widely concerned in the field of transgenic detection because of its short reaction time, high sensitivity and strong specificity. In this study, specific primers and probes were designed and screened for the exogenous inserted linked region of Bt11 in transgenic maize, and a rapid and accurate fluorescent RPA detection method was established. The PCR amplification was completed within 20 min at 39 鈩，
