RUBIDIUM IODIDE 99.9% (C005B-245679)

General description

A cell-permeable, photo-stable nitric oxide (NO) fluorescent indicator with a detection limit of ~3 nM. Intracellularly releases DAF-FM (Cat. No. 251515) by the action of esterases. Reacts with NO, in the presence of O₂, resulting in a triazolo-fluorescein analog (DAF-FM T) that exhibits about 160-fold greater fluorescence quantum efficiency. The fluorescence is reported to be stable above pH 5.8.

A cell-permeable, photo-stable nitric oxide (NO) fluorescent indicator with a detection limit of ~3 nM. Releases DAF-FM (Cat. No. 251515) by the action of intracellular esterases. Reacts with NO, in the presence of oxygen, resulting in the formation of a triazolo-fluorescein analog (DAF-FM T) that exhibits about 160-fold greater fluorescence quantum efficiency. The fluorescence intensity is reported to be stable above pH 5.8. Excitation max.: ~500 nm; emission max.: ~515 nm.
