Confocal micrograph of the cytoskeleton of a mixed population of granule neurons and glial cells. The F-actin was stained with red-fluorescent Texas Red®-X phalloidin (Cat. no. T7471). The microtubules were detected with a mouse monoclonal anti–ß-tubulin primary antibody and subsequently visualized with the green-fluorescent Alexa Fluor® 488 goat anti–mouse IgG antibody (Cat. no. A11001). The image was contributed by Jonathan Zmuda, Immunomatrix, Inc.
