| Abstract: | A method for preparing tissue sections for automatic image analysis of glyco-gen is described. Large semithin seaions of epoxy embedded tissue fixed in glutaraldehyde osmium were stained with Schiff reagent and acriflavine (fluorescent staining) after resin removal and periodic acid oxidation in ethanol. We found it essential to avoid tissue rehydra-tion before final staining. The Schiff stain permits an assessment of the cellular volume of glycogen, and the acriflavine allows a fluorometric evaluation of glycogen density. |
