| Victoria blue | Any of several blue diphenylnaphthylmethane derivatives; used as a stain in histology. Origin: Queen Victoria (05 Mar 2000) |
|---|---|
| patent blue V | A sulfonated triphenylmethane dye reduced and decolorised with zinc and acetic acid to produce a stable solution; used to demonstrate haemoglobin peroxidase. Synonym: patent blue V. (05 Mar 2000) |
| celestine blue B | A dye recommended as a substitute for haematoxylin when it is unavailable. (05 Mar 2000) |
| cellular blue nevus | A large, acquired blue nevus in which melanocytes are often clear and large, alternating with pigmented spindle cells and which may expand deeply into the subcutis; malignant change is very rare. (05 Mar 2000) |
| rhodanile blue | A dye mixture, considered by some to be a salt of rhodamine B and Nile blue, used to stain keratinised epithelium (red) and fibroblasts (blue), as well as spermatozoa and normal and pathologic acidophilic, basophilic, and certain neutrophilic elements of cells and tissues; used as a substitute for haematoxylin and eosin. (05 Mar 2000) |
| Perls' Prussian blue stain | <technique> A stain for ferric iron as in haemosiderins, using potassium ferrocyanide in acetic acid or dilute hydrochloric acid followed by a red counterstain such as safranin O or neutral red; various haemosiderins and most mineral irons give a blue-green reaction, while nuclei stain red. (05 Mar 2000) |
| methyl blue | A sulfonated triphenylrosaniline dye used as a stain for cytoplasm, collagen, and Negri bodies, and as an antiseptic. (05 Mar 2000) |
| methylene blue | <chemical> Methylthionine chloride; dark green crystals or crystalline powder having a bronze-like luster, readily reduced to colourless leukomethylene blue, which in turn is readily oxidised to methylene blue. Used as a bacteriologic stain and as an indicator, and administered orally or intravenously in the treatment of congenital methemoglobinaemia and cyanide poisoning. Pharmacological action: anti-infective agents, urinary, antidotes, dyes. Chemical name: Phenothiazin-5-ium, 3,7-bis(dimethylamino)-, chloride (12 Dec 1998) |
| Coomassie blue | Stain commonly used non-specifically for proteins on gels. Recently renamed Kenacid Blue. (18 Nov 1997) |
| Coomassie brilliant blue R-250 | A general protein stain used in electrophoresis because of its unusual sensitivity. Origin: originally, a proprietary name of Imperial Chemical; Coomassie (Kumasi), Ghana (05 Mar 2000) |
| polychrome methylene blue | An alkaline solution of methylene blue which undergoes progressive oxidative demethylation with aging (ripening) to produce a mixture of methylene blue, azures, and methylene violet; boiling with sodium carbonate or other oxidizing agents accomplishes this result quickly, although it is not as highly regarded. (05 Mar 2000) |
| cresyl blue | C17H20N3OCl; Aminodimethylaminoethyldiphenazonium chloride;a basic oxazin dye used for staining the reticulum in young erythrocytes (reticulocytes); also used in vital staining and as a selective stain for gastric surface epithelial mucin and other acid mucopolysaccharides. (05 Mar 2000) |
| Prussian blue | Fe4(Fe(CN)6)3; ferric ferrocyanide;a dye used to colour injection masses for blood vessels and lymphatics, and in staining of siderocytes. Synonym: Prussian blue. (05 Mar 2000) |
| prussian blue reaction | The reaction of potassium ferrocyanide with ferric iron to yield a dark blue precipitate at the sites of the ferric iron. Used to determine ferric iron in tissues, particularly in the diagnosis of disorders of iron metabolism. (12 Dec 1998) |
| Prussian blue stain | <technique> A stain employing acid potassium ferrocyanide to demonstrate iron, as in siderocytes. (05 Mar 2000) |
