There are two eosin variants typically used in histology: eosin Y which is slightly yellowish and eosin B which is slightly bluish. The term special stains has long been used to refer to a large number of alternative staining techniques that are used when the H&E does not provide all the information the pathologist or researcher needs. These sections of formalin-fixed submucosa have been stained with Masson trichrome stain. From translational research to routine diagnostics or AI development. Figure 8: Masson's Trichrome (skin). Even when advanced staining methods are used, the H&E stain still forms a critical part of the diagnostic picture as it displays the underlying tissue morphology which allows the pathologist/researcher to correctly interpret the advanced stain. 0000016143 00000 n Anatomic Pathology Special Stains - Cleveland Clinic This autonomic ganglion from the myenteric plexus, located between the smooth muscle layers of the muscularis externa of the small intestine, contains ganglionic neurons that show well-defined basophilic Nissl substance (aggregations of endoplasmic reticulum and ribosomal RNA) in their cytoplasm. Alcian Blue is normally prepared at pH 2.5 and is used to identify acid mucopolysaccharides and acidic mucins.
