無(wú)需針對(duì)每種蛋白制備特異性抗體，無(wú)需構(gòu)建轉(zhuǎn)基因體系，高通量檢測(cè)轉(zhuǎn)錄因子及DNA結(jié)合蛋白的結(jié)合位點(diǎn)。

藍(lán)景科信為您提供DAP-seq全流程技術(shù)服務(wù)和個(gè)性化數(shù)據(jù)分析，具有100多個(gè)物種，2000多個(gè)轉(zhuǎn)錄因子的實(shí)驗(yàn)經(jīng)驗(yàn)，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(xué)和表觀遺傳學(xué)研究中，轉(zhuǎn)錄因子結(jié)合位點(diǎn)（Transcription Factor Binding Sites, TFBS）的發(fā)掘一直是研究熱點(diǎn)之一。傳統(tǒng)的ChIP-seq（染色質(zhì)免疫共沉淀測(cè)序）方法，在抗體質(zhì)量很好的情況下能夠有效檢測(cè)到TFBS。然而，好的抗體可遇不可求，這限制了ChIP-seq更廣泛的應(yīng)用。

2016年，O'Malley RC等人在Cell上發(fā)表了使用DAP-seq技術(shù)，快速繪制轉(zhuǎn)錄因子調(diào)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(shí)驗(yàn)方法。DAP-seq技術(shù)使TFBS的研究不再局限于任何生物，不再受抗體質(zhì)量的限制，為生命科學(xué)和醫(yī)學(xué)領(lǐng)域轉(zhuǎn)錄因子的研究提供了新型高效的工具。
