Fluorescent probe and pH indicator. It fluoresces blue in acidic solutions and in acidic organelles but fluoresces green in more basic organelles. This compound is potentially useful as a coloring agent, biological stain or optical detecting reagent. It is used in water-in-oil-in-water emulsions and as a substrate for lipase activity. Spectral data: λex 375nm, λem 404nm in water.Product References(1) S.D. Dowling, et al.; Macromolecules 19, 344 (1986) | (2) K.N. Bakeev, et al.; Macromolecules 24, 4575 (1991) | (3) N.S.
