Product Description: PDMPO, a lysosome pH indicator, is an excellent fluorescent acidotropic reagent for fluorescence imaging. PDMPO is a potent tool with which to study acidic organelles of live cells. PDMPO exhibits pH-dependent dual-excitation and dual-emission spectral peaks. PDMPO produces a blue fluorescence in weakly acidic organelles and shifts to yellow in more acidic lysosomes (Abs=329 nm; Em=440 nm)[1].
Formula: C20H22N4O3
