| Hazard Information | Back Directory | [Uses]
DAF-FM has been used in the visualization of nitric oxide (NO) in root sections of wheat seedlings. It has also been used to label neural crest (NC) cells. | [Uses]
DAF-FM is important reagent for quantitating low concentrations of nitric oxide in solution. This compound is essentially nonfluorescent until it reacts with NO to form a fluorescent benzotrizole. | [Uses]
DAF-FM solution has been used as a fluorescent probe for detecting nitric oxide (NO) from plant samples. | [Biochem/physiol Actions]
DAF-FM is a highly sensitive, photo-stable fluorescent probe for the detection of nitric oxide (NO). DAF-2 is the original compound and is widely used, but DAF-FM is more sensitive to nitric oxide (NO) compared with DAF-2. DAF-FM is more photo-stable and less pH sensitive than DAF-2. DAF-FM is not quite as cell-permeable as the diacetate derivative, DAF-FM, but it does not need to be activated by cytosolic enzymes. |
