轉錄調控-DAP-seq

260+物種，4000+轉錄因子的DAP-seq實戰經驗，無需抗體，高通量鑒定轉錄因子的下游基因，藍景科信已助力客戶在許多期刊發表文章，例如：Cell，Science，Molecular Plant，Plant Biotechnology Journal，Journal of Advanced Research，Plant Cell，PNAS，Plant Communications，Journal of Integrative Plant Biology，Molecular Horticulture，New Phytologist，International Journal of Biological Macromolecules，Horticulture Research，Current Biology，Plant Physiology等。

在功能基因組學和表觀遺傳學研究中，轉錄因子結合位點（TFBS）的發掘一直是研究熱點。傳統的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。

DAP-seq技術的出現，使TFBS 的研究不再局限于物種，不再受抗體質量的限制，為生命科學領域轉錄因子的研究提供了新的有效工具。
