A fluorescent double stain for visualization of neural tissue by confocal laser scanning microscopy.

We present a fast and simple method for a general, fluorescent double stain that differentially labels various cellular components and visualizes all cells in confocal laser scanning microscopy. The technique is useful for two- and three-dimensional visualization of neural tissue and facilitates quantification of a variety of neuroanatomical parameters. Examples from cerebellum and retina are shown to demonstrate the broad applicability.
