We report the first fluorescent diamino-chalcone library and its application in the discovery of a mouse embryonic stem cell (mESC) probe. CDg4, a novel green fluorescent mESC probe was discovered through a high-content image based screening of 160 members of the chalcone library. Interestingly, the molecular binding target of CDg4 was identified as the glycogen of the stem cell colony surface, rather than a conventional protein target from an intracellular source.
我们报道了第一个荧光二氨基查尔酮库及其在小鼠胚胎干细胞(mESC)探针发现中的应用。通过对160个查尔酮库成员进行高通量图像筛选,发现了一种新型绿色荧光mESC探针CDg4。有趣的是,CDg4的分子结合靶标被确定为干细胞集落表面的糖原,而不是传统的来自细胞内的蛋白质靶标。
