Enzyme histochemical demonstration of alkaline phosphatase activity in plastic-embedded tissues using a Gomori-based cerium-DAB techniqueH van Goor, PO Gerrits and MJ Hardonk Department of Pathology, University of Groningen, The Netherlands. We describe a new method for light microscopic demonstration of alkaline phosphatase (ALP) activity in plastic-embedded sections. Rat tissues were fixed in acetone (-20 degrees C), infiltrated in glycol methacrylate (GMA), and embedded at 0 degrees C. Sections were cut at 1 and 2 microns, dried at room temperature, and incubated in the conventional Gomori medium. Cerium chloride was used to convert calcium phosphate into cerium phosphate, which was subsequently converted into cerium perhydroxide. The slight yellow precipitate of cerium perhydroxide was amplified using 3,3'-diaminobenzidine tetrahydrochloride (DAB). For comparison, tissue sections were processed according to the calcium-cobalt method. The method described combines exact localization of ALP activity with optimal preservation of tissue morphology.
