Application

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 (Ex: 500 nm; Em: 515 nm; dectection limit: 3 nM) is more photo-stable and less pH sensitive than DAF-2. DAF-FM is not quite as cell-permeable as the diacetate derivative, but it does not need to be activated by cytosolic enzymes.

Bio-protocol, 7(18), e2559-e2559 (2017-09-20)
In plant cells, the analysis of protein S-nitrosothiols (SNOs) under physiological and adverse stress conditions is essential to understand the mechanisms of Nitric oxide (NO)-based signaling. We adapted a previously reported protocol for detecting protein SNOs in animal systems (
