摘要: The invention encompasses kits for an improved method for measuring membrane potential using compounds of the formula I as potentiometric probes. These probes may be used in combination with other fluorescent indicators such as Indo-1, Fura-2, and Fluo-3, such probes may be used in microplate reading devices such as FLIPR™, fluorescent imaging plate reader, sold by Molecular Devices Corp., of Sunnyvale, Calif.; flow cytometers; and fluorometers. Such probes are used to measure membrane potential in live cells.

摘要: Systems, including compositions and methods, for measuring pH, particularly in cells, organelles, and other samples. The compositions include pH-sensitive fluorescent and fluorogenic 2′,7′-dialkylfluorescein derivatives and associated nonfluorescent precursor compounds. The compositions may permit ratiometric measurement in the excitation spectrum and the emission spectrum. The methods include adding a precursor compound to a sample cell, incubating the sample cell to release the free indicator, illuminating the sample cell, and detecting the fluorescence response of the free indicator.
