| Birch-Hirschfeld stain | <technique> An obsolete stain for demonstrating amyloid, using Bismarck brown and crystal violet; amyloid is usually stained a bright ruby red, whereas the cytoplasm of cells is not stained and nuclei are brown. (05 Mar 2000) |
|---|---|
| Bowie's stain | <technique> A stain for juxtaglomerular granules in which the kidney sections are stained in a mixture of Biebrich scarlet red and ethyl violet; juxtaglomerular granules and elastic fibres are stained a deep purple, erythrocytes are amber, and background tissue appears in shades of red. (05 Mar 2000) |
| Brown-Brenn stain | <technique> A method for differential staining of Gram-positive and Gram-negative bacteria in tissue sections; it utilises a modified Gram stain of crystal violet, Gram's iodine, and basic fuchsin. (05 Mar 2000) |
| Cajal's astrocyte stain | <technique> A method for demonstrating astrocytes by impregnation in a solution containing gold chloride and mercuric chloride. (05 Mar 2000) |
| carbol-thionin stain | <technique> A stain useful for demonstrating typhoid bacilli in films and sections, and for Nissl substance. (05 Mar 2000) |
| Macchiavello's stain | <technique> A basic fuchsin-citric acid-methylene blue sequence in smears which produces red staining of rickettsiae and inclusion bodies, with nuclei staining blue. (05 Mar 2000) |
| MacNeal's tetrachrome blood stain | <technique> A stain for blood smears comprised of a mixture of methylene blue, azure A, methylene violet, and eosin Y. (05 Mar 2000) |
| Padykula-Herman stain | <technique> For myosin ATPase, a technique similar to that of Gomori's non-specific alkaline phosphatase stain, except that incubation is carried out with ATP as the substrate at pH 9.4 in the absence of Mg++; enzyme activity is demonstrated as blackened deposits in the A band of striated muscle sarcomeres; control tissue sections lacking substrate and containing sulfhydryl inhibitors are necessary. (05 Mar 2000) |
| Paget-Eccleston stain | <technique> An aldehyde-thionin-PAS-orange G staining technique modified to identify seven different cell types in the anterior pituitary gland. (05 Mar 2000) |
| van Ermengen's stain | <technique> A method for staining flagella which utilises glacial acetic acid, osmic acid, tannic acid, silver nitrate, gallic acid, and potassium acetate. (05 Mar 2000) |
| van Gieson's stain | <technique> A mixture of acid fuchsin in saturated picric acid solution, used in collagen staining. (05 Mar 2000) |
| Rambourg's chromic acid-phosphotungstic acid stain | <technique> A stain for glycoproteins, used with an electron microscope, with which ultrathin tissue sections reveal complex carbohydrates in the same locations as shown by Rambourg's periodic acid-chromic methenamine-silver stain. (05 Mar 2000) |
| Rambourg's periodic acid-chromic methenamine-silver stain | <technique> A stain for glycoproteins, used with an electron microscope, adapted from the Gomori-Jones periodic acid-methenamine-silver stain; it produces silver deposits in mature saccules of the Golgi apparatus, lysosomal vesicles, cell coat, and basement membranes. (05 Mar 2000) |
| malarial pigment stain | <technique> A stain using phloxine-toluidine blue O sequence; malarial pigment and nuclei are bluish, erythrocytes and cytoplasm are red to orange; found in phagocytic cells of the reticuloendothelial system. (05 Mar 2000) |
| Maldonado-San Jose stain | <technique> A staining method for staining pancreatic islet cells, using a phloxine-azure B-haematoxylin sequence; alpha cells are purple, beta cells are violet-blue, delta cells are light blue, and exocrine cells are grayish blue with red secretion granules.
