A ratiometric fluorescent probe for Ca2+ based on 1,3,4-oxadiazole derivative has been designed and developed. The probe exhibits a large Stokes shift of 202 nm and a highly selective ratiometric emission response (490/582 nm) to Ca2+ over other metal cations. Additionally, the probe can readily reveal the changes of intracellular Ca2+ concentration in living human umbilical vein endothelial cells.
我们设计并开发了一种基于 1,3,4-噁二唑衍生物的 Ca2+ 比率荧光探针。该探针的斯托克斯位移为 202 nm,对 Ca2+ 的比率发射响应(490/582 nm)比其他金属阳离子具有更高的选择性。此外,该探针还能轻易揭示活人脐静脉内皮细胞中细胞内 Ca2+ 浓度的变化。
