DAN-1 EE (hydrochloride)

DAN-1 EE (hydrochloride) (CAS No.: 1049720-51-5) is a specialized fluorescent probe designed for the sensitive and selective detection of nitrite in biochemical and biological systems, positioning it as a valuable analytical tool in redox biology and nitric oxide–related research. Functionally, this small-molecule indicator enables real-time monitoring of nitrite dynamics in vitro and within cellular environments, where it exhibits a robust and responsive fluorescence signal upon interaction with nitrite, facilitating precise quantification of concentration changes. Although not a therapeutic agent, its mechanism of action is based on chemical reactivity with nitrite species, making it particularly relevant for studying nitrogen oxide metabolism, oxidative stress pathways, and associated signaling processes. In cellular assays, DAN-1 EE (hydrochloride) demonstrates high sensitivity, typically operating effectively within low micromolar to submicromolar detection ranges depending on experimental conditions. It is broadly applied in biochemical assays, live-cell imaging, and environmental or physiological monitoring workflows to investigate nitrite fluctuations and their biological implications. Experimental concentrations and protocols may vary according to specific assay designs, cell types, and research objectives, underscoring its adaptability across diverse biomedical and drug discovery applications.
