11. Brazilin has been used since at least the Middle Ages to hematoxylin , having one fewer hydroxyl group. 12. Routine hematoxylin and eosin ( H & E ) and immunoperoxidase staining will be adequate to rule out node involvement. 13. The hematoxylin body may be green, blue, or purple with the Papanicolaou stain and magenta with Romanowsky stains. 14. Hematoxylin and eosin ( H & E stain ) is the most commonly used light microscopical stain in histology and histopathology.15. The most commonly used stain in histopathology is a combination of hematoxylin and eosin ( often abbreviated H & E ). 16. Prolactin cells are acidophilic by hematoxylin & eosin stains and comprise about 20 % of all cells in the anterior pituitary gland. 17. Fluid leaks into alveoli, producing an exudate seen as honeycomb / cotton candy appearance on hematoxylin and eosin-stained slides. 18. The tissue section in the image shown here was also counterstained with hematoxylin to stain DNA in nuclei a blue-gray color. 19. Within cellular biology, " chromophobic " cells are a classification of cells that do not attract hematoxylin , and is related to chromatolysis. 20. Part of the small intestine can be stained with hematoxylin and eosin ( H & E ), which will show oocysts attached to the epithelial cells.
