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.
