Blue emitting Coumarin 343 dye can form a FRET pair with fluorescein (FAM). An amine reactive form, activated NHS ester.
This amine-reactive NHS ester contains an aminohexanoyl linker between the fluorophore, and the reactive group. This linker provides better solubility and spatial separation between the fluorophore, and the target molecule being labeled.
This reagent can be used to design FRET based assays with FAM as acceptor, and to construct systems which harvest blue light energy.
蓝色发射香豆素 343 染料可与荧光素 (FAM) 形成 FRET 对。 胺反应形式，活化的 NHS 酯。
这种胺反应性 NHS 酯在荧光团和反应性基团之间含有氨基己酰基接头。 这种接头在荧光团和被标记的目标分子之间提供了更好的溶解度和空间分离。
该试剂可用于设计以 FAM 为受体的基于 FRET 的分析，并构建收集蓝光能量的系统。
