      Description
      OverviewA photo-stable nitric oxide (NO) fluorescent indicator with a detection limit of ~3 nM. 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 intensity is reported to be stable above pH 5.8.

      Synonyms3-Amino, 4-aminomethyl-2ʹ,7ʹ-difluorofluorescein
      DescriptionA photo-stable nitric oxide (NO) fluorescent indicator with a detection limit of ~3 nM. Reacts with NO, in the presence of oxygen, resulting in the formation of a triazolo-fluorescein analog (DAF-FM T) that exhibits about 160-fold greater fluorescence quantum efficiency. The fluorescence intensity is reported to be stable above pH 5.8. Excitation max.: ~500 nm; emission max.: ~515 nm.
      FormPale yellow solution
      FormulationIn DMSO.
      Intert gas (Yes/No) Packaged under inert gas
      Recommended reaction conditionsThe reagent is provided at ~7 mM concentration. Prepare a 1000-fold dilution in 0.1 M phosphate buffer, pH 7.4 before use. BSA and phenol red may affect fluorescence.
