The combination of hematoxylin and eosin is the most commonly used method to stain sections of tissues. Hematoxylin, a basic dye, binds to acidic components of a tissue, which are thus said to be ... WebThe overall color of ES-stained fecal smears is a gray-green or gray-blue monotone with very little pink tone, and the contrast among the range of colors is less than that seen with WT. Stain intensity among both ES- and WT-stained smears was acceptable, and there were no problems with stain deposition. TABLE 1

WebMar 29, 2013 · The Perl's iron stain (Prussian blue reaction) is a common and reliable stain for detecting iron. Iron is stored in the hepatocytes as a soluble form (ferritin) and an insoluble form (hemosiderin). With the H&E stain, the latter is seen as coarsely granular brown refractile granules in the cytoplasm, whereas ferritin is not seen. cynthia jordan mdWebHematoxylin and Eosin (H&E) Stain H&E is probably the most widely used stain in histology laboratories as it shows a broad range of cytoplasmic, nuclear, and extracellular matrix features. Tap water may not give consistent bluing due to fluctuations in pH, or may contain contaminants that can destain hematoxylin, such as iron, sulfur or chlorine. 4 cynthia jordan pcpWebThe phosphotungstic acid-hematoxylin (PTAH) stain is useful for demonstrating: Muscle striations.
