A Ziehl–Neelsen stain is an acid-fast stain used to stain species of Mycobacterium tuberculosis that do not stain with the standard laboratory staining procedures such as Gram staining. This stain is performed through the use of both red coloured carbol fuchsin that stains the bacteria and a counter stain such as methylene blue .
In pathology, the Grocott–Gömöri's methenamine silver stain, abbreviated GMS, is a popular staining method in histology. The stain was originally named after György Gömöri, the Hungarian physician who developed the stain. It is used widely as a screen for fungal organisms. It is particularly useful in staining carbohydrates.
Mast cells are relatively sparse, potentially demonstrated with special stains, preferably tryptase stain. [14] Extravasated erythrocytes are present in about 50% of the cases [14] No vasculitis. [14] Dermatitis herpetiformis Subepidermal vesicles and blisters associated with accumulation of neutrophils at the papillary tips. [24]
The most commonly used stain in histology is a combination of hematoxylin and eosin (often abbreviated H&E). Hematoxylin is used to stain nuclei blue, while eosin stains the cytoplasm and the extracellular connective tissue matrix of most cells pink. There are hundreds of various other techniques which have been used to selectively stain cells.
Clusters of bacteria (arrow) shown on Warthin–Starry stain. The Warthin–Starry stain ( WS ) is a silver nitrate -based staining method (a silver stain ) used in histology. It was first introduced in 1920 by American pathologists Aldred Scott Warthin (1866–1931) and Allen Chronister Starry (1890–1973), for the detection of spirochetes .
In histology, histopathology, and clinical pathology, Perls Prussian blue is a commonly used method to detect the presence of iron in tissue or cell samples. [ 1 ] : 235 [ 2 ] [ 3 ] [ 4 ] Perls Prussian Blue derives its name from the German pathologist Max Perls (1843–1881), who described the technique in 1867. [ 2 ]
The H&E staining procedure is the principal stain in histology [3] [7] [2] [5] in part because it can be done quickly, [7] is not expensive, and stains tissues in such a way that a considerable amount of microscopic anatomy [9] [10] is revealed, [7] [5] [4] and can be used to diagnose a wide range of histopathologic conditions.
