Research Use Only

This dye can be used as a low pH indicator similar 5-and-6-Carboxy-27-dichlorofluorescein, and is also useful as a general green fluorescent label. Carboxy-2,7-dichlorofluorescein is significantly more photostable than carboxyfluorescein. lambdaEx/lambdaEm = 504/529 nm (pH 8) epsilon = 90,000 Yellow solid soluble in DMSO, DMF or basic water (pH >7) Store at 4°C and protect from light C21H10Cl2O7 MW: 445
