Modifying cyclic cell-penetrating peptides with DABCYL derivatives can enhance the formation of nucleation zones for small fluorescent cargoes. Structure variations of the DABCYL moiety significantly increased the cellular uptake efficiency of ubiquitin, resulting in efficient cytosolic transport at nanomolar concentrations.
用 DABCYL 衍生物修饰环状细胞穿透肽可以增强小荧光货物成核区的形成。DABCYL 部分的结构变化显着提高了泛素的细胞摄取效率,从而在纳摩尔浓度下实现有效的胞质转运。
