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 compounds (aldehydes and ketones) by means of reductive amination.

带有胺基的荧光素衍生物,含有纯的6-异构体的荧光团。 该试剂可用于通过酶促氨基转移对生物分子进行修饰。 它的脂肪胺基团也与亲电子试剂(如活化酯)发生反应。 这种胺也可以通过还原胺化与羰基化合物(醛和酮)共轭。
