Carboxy SNARF®-1, acetoxymethyl ester, acetate is a cell-permeant pH indicator that has a pKa of ~7.5 after de-esterification; thus, it is useful for measuring pH changes between pH 7 and pH 8. Carboxy-SNARF®-1 exhibits a significant pH-dependent emission shift from yellow-orange to deep red fluorescence under acidic and basic conditions, respectively. This pH dependence allows the ratio of the fluorescence intensities from the dye at two emission wavelengths - typically 580 nm and 640 nm - to be used for quantitative determinations of pH.
