of the recent fundamental advances in this field is the development of fluorogenic dyes - compounds that have no pronounced fluorescence in the free state but acquire it upon binding with the target object, allowing for simple no-wash labeling. Among these dyes, it is worth to note compounds whose fluorescence is particularly sensitive to the properties of the microenvironment (e.g., solvent), which
荧光染色是研究生命系统必不可少的方法。该领域最近的一项基本进展是开发了荧光染料-荧光染料在自由状态下没有明显的荧光,但在与目标物体结合后会获得荧光,因此无需清洗标签。在这些染料中,值得注意的是其荧光对微环境(例如溶剂)的特性特别敏感的化合物,例如可用于染色细胞器。在本文中,我们提出了一种新颖的技术,用于创建具有较大斯托克斯频移的环境敏感型和红移荧光染料。新型染料基于GFP发色团核心,并显示出最大发射位置和荧光量子产率的高溶剂依赖性变化。
