Beschreibung
5(6)-Carboxyfluorescein is a mixture of 5-carboxy and 6-carboxy derivatives of fluorescein. It is commonly used to label biomolecules through a reaction involving the carboxyl group. Unlike its succinimidyl ester derivative CFSE , 5(6)-carboxyfluorescein is membrane impermeant. As a result, it can be used in studies of membrane permeability. 5(6)-Carboxyfluorescein displays excellent fluorescence (excitation/emission at 492/514 nm, respectively), and its excitation maximum closely matches the 488 nm spectral line of argon-ion lasers.
Chemische Eigenschaften
Dark-Orange to Brown Solid
Verwenden
As a popular probe of determination of intracellular pH, 5(6)-Carboxyfluoresceincan be used as useful reagent for the preparation of hydrolytically stable fluorescent conjugates and a useful starting material for the synthesis of other fluorescein-derives reagent
Solubility in organics
5(6)-Carboxyfluorescein is soluble in organic solvents such as ethanol, DMSO, and dimethyl formamide. The solubility of 5(6)-carboxyfluorescein in these solvents is approximately 5, 0.5, and 1 mg/ml, respectively.
