轉(zhuǎn)錄因子結(jié)合位點(diǎn)方法

高通量檢測轉(zhuǎn)錄因子或DNA結(jié)合蛋白在基因組上的結(jié)合位點(diǎn)

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ChlP-seq(染色質(zhì)免疫共沉淀測序)方法，在抗體質(zhì)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ChlP-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)和醫(yī)學(xué)領(lǐng)域轉(zhuǎn)錄因子的研究提供了新的有效工具。
