FAM amine, FITC-NH2,氨基修飾的綠色熒光素
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

FAM amine, 6-isomer

Fluorescein derivative with amine group, contains pure 6-isomer of the fluorophore. This reagent can be used for the modification of biomolecules by enzymatic transamination. Its aliphatic amine groups also reacts with electrophiles (like activated esters). This amine can be also conjugated with carbonyl pounds (aldehydes and ketones) by means of reductive amination.
