When applying aqueous media to mount thick specimens, air bubbles occur frequently between coverslips and slide glasses. This results in an increase of background signal by confocal microscopy. Using Spurr's resin as a mounting medium, we could observe thick specimens with oil immersion objective lens without the use of coverslips, then avoid air bubbles near the specimen. Fading of the fluorescence appeared to be less in specimens mounted by the resin than in specimens mounted by aqueous media. Further, the new method increased depth of field so that more planes of specimens could be analyzed.

D018613 Microscopy, Confocal A light microscopic technique in which only a small spot is illuminated and observed at a time. An image is constructed through point-by-point scanning of the field in this manner. Light sources may be conventional or laser, and fluorescence or transmitted observations are possible.
