CoroNa Green dye is a sodium ion indicator that exhibits an increase in green fluorescence emission intensity upon binding Na+
, with little shift in wavelength. Like our other sodium indicators, SBFI (Cat. nos. S1262, S1263, S1264) and Sodium Green dye (Cat. nos. S6900, S6901), the CoroNa Green indicator allows spatial and temporal resolution of Na+
concentrations in the presence of physiological concentrations of other monovalent cations. CoroNa Green AM dye loads into cells more efficiently than does Sodium Green tetraacetate, and the CoroNa Green indicator responds to a broader range of Na+
concentration. With absorption/emission maxima of ∼492/516 nm for the Na+
-bound form, CoroNa Green dye can be detected by any instrument that can detect fluorescein. CoroNa Green dye is also available in a cell impermeant form (Cat. no. C36675).Learn more about ion indicators including calcium, potassium, pH, and membrane potential indicators ›
