Description
A cell-impermeable fluorescent pH probe; ex/em= 403 and 450 nm, the intensities of which decrease and increase, respectively, as pH increases from 5 to 9/510 nm; has been used in excitation ratio imaging to monitor changes in and measure the pH of endocytosed liposomes, acidic organelles, or the cytoplasm in live cell applications; sensitive to fluorescence quenching by viologens, which can be reversed in the presence of glucose or other monosaccharides, and has been used as a glucose and carbohydrate sensor
