Categories: Fluorescent Detection, Fluorescent Detection
Photo-stable fluorescent probe (Ex: ~560nm, Em: 575nm) for the detection of nitric oxide (NO) in presence of oxygen, resulting in a triazolo-rhodamine analog (DAR-4M T) that exhibits about 840-fold greater fluorescence quantum efficiency. Suitable probe for monitoring RNS production, but not NO alone. Stable in a pH range of 4-12. Detection limit ~10nM.
