Fluorescein diacetate CAS596-09-8Also called FDA, can pass through the cellular membrane and as fluorescein accumulation in living cells. As compared with BCECF or fluorescein hydrophilic calcein low, fluorescein leakage from cells was also high. FDA is also used in flow cytometry. Fluorescence excitation and emission wavelengths are 488nm and 530nm.
