Coumarin 343 X NHS ester,綠色熒光染料
目前Cyanine系列染料以兩種異構(gòu)體的形式存在，一種是非磺化花青素（non-sulfonated cyanines），一種是磺化花青素（sulfonatedcyanine）。兩者的光譜性質(zhì)幾乎*，因此大部分應(yīng)用可相互替換。

產(chǎn)品介紹

Coumarin 343 X NHS ester

香豆素

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.
