Coumarin 343 is a blue emitting fluorophore with an emission maximum around 480 nm. This dye forms a FRET pair with fluorescein, and can harvest blue light energy for the subsequent transfer to other fluorophores.
The azide derivative can be conjugated with alkynes in a copper-catalyzed and copper-free Click chemistry reactions. The molecule contains a long aminohexanoyl linker that provides separation between the dye, and the azide function.
香豆素 343 是一种蓝色荧光团，最大发射波长约为 480 nm。 这种染料与荧光素形成 FRET 对，并可以收集蓝光能量用于随后转移到其他荧光团。
叠氮化物衍生物可以在铜催化和无铜点击化学反应中与炔烃结合。 该分子含有一个长的氨基己酰基接头，可在染料和叠氮化物功能之间提供分离。
