轉(zhuǎn)錄調(diào)控-DAP-seq

100+物種，2000+轉(zhuǎn)錄因子的DAP-seq實(shí)戰(zhàn)經(jīng)驗(yàn)，無(wú)需抗體，高通量鑒定轉(zhuǎn)錄因子的下游基因，藍(lán)景科信已助力客戶(hù)在許多期刊發(fā)表文章，例如：Molecular Plant，The Plant Cell，Plant Physiology，Plant Biotechnology Journal，Journal of Integrative Plant Biology，New Phytologist等。

在功能基因組學(xué)和表觀遺傳學(xué)研究中，轉(zhuǎn)錄因子結(jié)合位點(diǎn)（TFBS）的發(fā)掘一直是研究熱點(diǎn)。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。

DAP-seq技術(shù)的出現(xiàn)，使TFBS 的研究不再局限于物種，不再受抗體質(zhì)量的限制，為生命科學(xué)領(lǐng)域轉(zhuǎn)錄因子的研究提供了新的有效工具。
