Application

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.

Biochem/physiol Actions

DAF-FM is a highly sensitive, photo-stable fluorescent probe for the detection of nitric oxide (NO).
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.

hygroscopic

Preparation Note

Color variation within the range from white to brown does not change performance.
