| Giemsa stain | <technique> Compound of methylene blue-eosin and methylene blue used for demonstrating Negri bodies, Tunga species, spirochetes and protozoans, and differential staining of blood smears; also used for chromosomes, sometimes after hydrolyzing the cytologic preparation in hot hydrochloric acid, and for showing chromosome G bands; often used in glycerol-methanol buffer solution.

| Maximow's stain | <technique> For bone marrow, an alum-haematoxylin and azure II-eosin stain used to distinguish granulated leukocytes, mast cells, and cartilage. (05 Mar 2000) |
| Mayer's haemalum stain | <technique> A progressive nuclear stain also used as a counterstain. (05 Mar 2000) |
| Mayer's mucicarmine stain | A red stain containing aluminum chloride and carmine; used to detect epithelial mucins and mucin-secreting adenocarcinomas; also used to demonstrate the capsule of Cryptococcus neoformans and other fungi. (05 Mar 2000) |
| Mayer's mucihematein stain | A violet-blue staining fluid containing aluminum chloride and haematein; used to detect connective tissue mucins. (05 Mar 2000) |
| May-Grunwald stain | <technique> A German equivalent of Jenner's stain, used for blood staining and in cytology; often used in combination with Giemsa stain; valuable in demonstrating parasitic flagellates. (05 Mar 2000) |
| PAS stain | <technique> A histochemical technique based on periodic acid oxidation of a substance containing the 1,2-glycol grouping. It is used for staining carbohydrates as the resulting dialdehyde reacts with Schiff reagent to form a coloured product. Substances that can be demonstrated include carbohydrates, mucins, cartilage matrix, collagen, reticulum, basement membranes, fibrin, thyroid colloid, amyloid, glomerular hyaline deposits, and a number of other secretions or tissue constituents. Also used in for staining gels on which glycoproteins have been run. See: periodic acid Schiff reaction Synonym: PAS stain. (22 Sep 2002) |
| Glenner-Lillie stain | <technique> For pituitary, a modification of Mann's methyl blue-eosin stain which changes the dye proportions, buffering the dye mixture, and staining at 60캜; basophils are stained blue to black, acidophils are dark red, chromophobe granules are gray to pink, and erythrocytes are orange; with modification, the method is also useful for enterochromaffin cells, goblet cells, Paneth cells, and pancreatic islet cells.

| C-banding stain | <technique> A selective chromosome banding stain used in human cytogenetics, employing Giemsa stain after most of the DNA is denatured or extracted by treatment with alkali, acid, salt, or heat; only heterochromatic regions close to the centromeres and rich in satellite DNA stain, with the exception of the Y chromosome whose long arm usually stains throughout. Synonym: centromere banding stain. (05 Mar 2000) |
| vital stain | <technique> A stain that is taken up by live cells and that can be used to stain, for example: a group of cells in a developing embryo in order to try to determine a fate map. (18 Nov 1997) |
| centromere banding stain | <technique> A selective chromosome banding stain used in human cytogenetics, employing Giemsa stain after most of the DNA is denatured or extracted by treatment with alkali, acid, salt, or heat; only heterochromatic regions close to the centromeres and rich in satellite DNA stain, with the exception of the Y chromosome whose long arm usually stains throughout. Synonym: centromere banding stain. (05 Mar 2000) |
| von Kossa stain | <technique> A stain for calcium in mineralised tissue, utilizing a silver nitrate solution followed by sodium thiosulfate; calcified bone but not osteoid is stained brown to black. Synonym: Kossa stain. (05 Mar 2000) |
| Golgi's stain | <technique> Any of several methods for staining nerve cells, nerve fibres, and neuroglia using fixation and hardening in formalin-osmic-dichromate combinations for various times, followed by impregnation in silver nitrate. (05 Mar 2000) |
| Gomori's chrome alum haematoxylin-phloxine stain | <technique> A technique used to demonstrate cytoplasmic granules, after Bouin's or formalin-Zenker fixatives, using oxidised haematoxylin plus phloxine; in the pancreas, beta cells are blue, alpha and delta cells are red, and zymogen granules are red to unstained; in the pituitary, alpha cells are pink, beta cells and chromophobes are gray-blue, and nuclei are purple to blue. (05 Mar 2000) |
| Gomori's methenamine-silver stain | <technique> Techniques for 1) argentaffin cells: a method using a methenamine-silver solution in combination with gold chloride, sodium thiosulphate, and safranin O; argentaffin granules appear brown-black against a green background; 2) urates: warm sections are treated directly with a hot methenamine-silver solution to produce a blackening of urates; 3) fungi: see Grocott-Gomori methenamine-silver stain; 4) melanin, which reduces silver nitrate.
