DAF-FM DA
3-Amino, 4-aminomethyl-2′,7′-difluorofluorescein Diacetate
A cell-permeable, photo-stable nitric oxide (NO) fluorescent indicator with a detection limit of ~3 nM. Intracellularly releases DAF-FM (Cat. No. 251515) by the action of esterases. Reacts with NO, in the presence of O2, resulting in a triazolo-fluorescein analog (DAF-FM T) that exhibits about 160-fold greater fluorescence quantum efficiency. The fluorescence is reported to be stable above pH 5.8.
