Application

DAF-FM DA has been used to measure the nitric oxide (NO) levels in liver tissue homogenates. It has also been used in NO staining for detection of NO from human umbilical vein endothelial cells (HUVECs).

Biochem/physiol Actions

DAF-FM DA is a cell-permeable fluorescent probe for the detection of nitric oxide (NO).
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.

Calorie restriction (CR) induces a metabolic shift towards mitochondrial respiration; however, molecular mechanisms underlying CR remain unclear. Recent studies suggest that CR-induced mitochondrial activity is associated with nitric oxide (NO) production. To understand the role of mitochondria in CR, we
