無需針對每種蛋白制備特異性抗體，無需構建轉基因體系，高通量檢測轉錄因子及DNA結合蛋白的結合位點。

藍景科信為您提供DAP-seq全流程技術服務和個性化數(shù)據(jù)分析，具有100多個物種，2000多個轉錄因子的實驗經(jīng)驗，已協(xié)助很多客戶成功發(fā)表文章。例如：Molecular Plant，The Plant Cell，Plant Physiology，Plant Biotechnology Journal，Journal of Integrative Plant Biology，New Phytologist，Cell等。

在基因功能組學和表觀遺傳學研究中，轉錄因子結合位點（Transcription Factor Binding Sites, TFBS）的發(fā)掘一直是研究熱點之一。傳統(tǒng)的ChIP-seq（染色質免疫共沉淀測序）方法，在抗體質量很好的情況下能夠有效檢測到TFBS。然而，好的抗體可遇不可求，這限制了ChIP-seq更廣泛的應用。

2016年，O'Malley RC等人在Cell上發(fā)表了使用DAP-seq技術，快速繪制轉錄因子調控靶向DNA區(qū)域圖譜的文章。2017年，Bartlett A等在Nature Protocols上發(fā)表了DAP-seq的實驗方法。DAP-seq技術使TFBS的研究不再局限于任何生物，不再受抗體質量的限制，為生命科學和醫(yī)學領域轉錄因子的研究提供了新型高效的工具。
