Thermo Fisher, C1272, 5-(and-6)-Carboxy SNARF™-1, Acetoxymethyl Ester, Acetate

Quantity: 20 x 50μg Carboxy SNARF™-1, acetoxymethyl ester, acetate is a cell-permeant pH indicator that has a pKaof ∼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.
