DAF-FM diacetate is an important reagent for quantification of low concentrations of nitric oxide in solution. This compound is essentially nonfluorescent until it reacts with NO to form a fluorescent benzotriazole. With excitation/emission maxima of 495 | [Biochem/physiol Actions]
DAF-FM DA is a cell-permeable fluorescent probe for the detection of nitric oxide (NO). DAF-2 is the original compound and is widely used, but DAF-FM and DAF-FM DA are more sensitive to nitric oxide (NO) compared with DAF-2 and more photo-stable and less pH sensitive. DAF-FM DA permeates well into living cells and is rapidly transformed into water-soluble DAF-FM by cytosolic esterases. | [in vivo]
Using sections of zebrafish embryos live-stained with DAF-FM DA (5 μM), could confirm that the fluorescent signals were predominantly located in areas of ongoing bone formation[1]. | [storage]
