General description

4,5-Diaminofluorescein diacetate (DAF-2 DA) solution is a membrane-permeable fluorescent probe, which measures nitric oxide (NO) in living cells. It is used to study the synthesis of NO in bovine aortic endothelial cells (BAECs). DAF-2 DA imaging shows that ciliated epithelial cells produces high amount of NO than non-epithelial inflammatory cells.

Application

Cell-permeable fluorescent detector of nitric oxide in living cells.

Nitric oxide (NO) is a regulatory molecule in the vascular system and its inhibition due to endothelial injury contributes to cardiovascular disease. The glycocalyx is a thin layer of glycolipids, glycoproteins, and proteoglycans on the surface of mammalian epithelial cells.

Alexander disease (AxD) is a fatal neurodegenerative disorder caused by mutations in glial fibrillary acidic protein (GFAP), which supports the structural integrity of astrocytes. Over 70 GFAP missense mutations cause AxD, but the mechanism linking different mutations to disease-relevant phenotypes

Olfaction, a chemosensory modality, plays a pivotal role in the orientation and behavior of invertebrates. The central olfactory processing unit in terrestrial stylomatophoran snails is the procerebrum, which contains NO synthesizing interneurons, whose oscillatory currents are believed to be the
