fluorescent dye for labelling of proteins

5-Carboxy-4',5'-dichloro-2',7'-dimethoxyfluorescein succinimidyl ester

5-Carboxy-4',5'-dichloro-2'7'-dimethoxyfluorescein NHS ester, single isomer (5-JOE-SE). Amine-reactive fluorescein dye marker for fluorescence labeling, especially for labeling of biomolecules (Abs: 522nm (? = 76.000 M-1cm-1), Em: 549nm). This single isomer, amine-reactive, fluorescein derivative is used as an orange fluorescent derivatization reagent for covalently labeling proteins and alkylamino modified nucleic acids.
