Fluorescence ratio imaging microscopy: temporal and spatial measurements of cytoplasmic pH

Abstract

Fluorescence ratio imaging microscopy (Tanasugarn, L., P. McNeil, G. Reynolds, and D. L. Taylor, 1984, J. Cell Biol., 98:717-724) has been used to measure the spatial variations in cytoplasmic pH of individual quiescent and nonquiescent Swiss 3T3 cells. Fundamental issues of ratio imaging that permit precise and accurate temporal and spatial measurements… (More)
