AbstractA hematoxylin and eosin procedure is described for staining formalin-fixed tissues embedded in glycolmethacrylate with emphasis on 1.5 micron sections. The staining method utilizes Gill's hematoxylin followed by a buffered eosin Y-phloxine B counterstain. Acidophilic and basophilic components of most stained tissue sections had an intense, sharp and clean appearance when observed by light microscopy.
