Description
5-Carboxyfluorescein succinimidyl ester is an aminereactive ester of single isomer 5-Carboxyfluorescein. It has principally been used to develop a variety of green fluorescent reagents and small fluorescent molecules due to its relatively high absorbance characteristics, excellent fluorescence quantum yield, and good water solubility. Carboxyfluorescein succinimidyl ester has recently become a popular probe for labeling cells intracellularly and tracking their mitotic activity by flow cytometry and other fluorescence- based assays through monitoring progressive twofold reductions in fluorescence intensity. Wavelength Maxima: Excitation 492nm, Emission 518nm
