转录调控-DAP-seq

100+物种，2000+转录因子的DAP-seq实战经验，无需抗体，高通量鉴定转录因子的下游基因，蓝景科信已助力客户在许多期刊发表文章，例如：Molecular Plant，The Plant Cell，Plant Physiology，Plant Biotechnology Journal，Journal of Integrative Plant Biology，New Phytologist等。

在功能基因组学和表观遗传学研究中，转录因子结合位点（TFBS）的发掘一直是研究热点。传统的ChIP-seq（染色质免疫共沉淀测序）方法，在抗体质量很好的情况下能够有效检测到TFBS。然而，好的抗体可遇不可求，这限制了ChIP-seq更广泛的应用。

DAP-seq技术的出现，使TFBS 的研究不再局限于物种，不再受抗体质量的限制，为生命科学领域转录因子的研究提供了新的有效工具。
