Confocal microscopy produces sharp images of structures within relatively thick specimens (up to several hundred microns). It is particularly useful for examining fluorescent specimens, such as fluorescent-stained cells or intact organisms (e.g., Drosophila or zebrafish embryos), and can localize intracellular antigens in dissociated cells. Its sensitivity even allows the monitoring of fluorescence in living organisms, making it possible to follow the movements of fluorescent probes such as GFP or dyes for specific organelles. This unit presents the theory of optical sectioning, describes the instrumentation of the technique, and offers practical guidelines for sample preparation and analysis.
