The actin cytoskeleton outlining individual cells is visualized by localized Green Fluorescent Protein. Imaged captured by Maureen Filak ('10) during the summer REU program. A video from some of Dr Halsell's earlier work can be seen on the Duke University Light Microscopy Core Facility's Gallery
||Arabidopsis root cells expressing GFP-tubulin
(green). One cell was injected with fluorescein, which has moved
to cells above and below (arrowheads). Spectral imaging on the
Nikon confocal was used
to separate the very similar signals from fluorescein and GFP.
Fluorescein has been false-colored red. Image by
