| 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) |
| sea-blue histiocyte | A histiocyte containing cytoplasmic granules that stain bright blue with haematologic stains such as Wright-Giemsa; found in bone marrow and in the spleen, associated with hepatosplenomegaly and thrombocytopenic purpura and in other blood diseases. (05 Mar 2000) |
| sea-blue histiocyte disease | Splenomegaly and mild thrombocytopenia, with histiocytes in the bone marrow which contain cytoplasmic granules that stain bright blue; sometimes familial; perhaps a lipidosis; autosomal recessive inheritance. (05 Mar 2000) |
| sea-blue histiocyte syndrome | <syndrome> Rare disorder consisting of splenomegaly, mild purpura secondary to thrombocytopenia, and occasionally, hepatic cirrhosis associated with the appearance of numerous histiocytes in the spleen and bone marrow which stain a sea-blue colour. It is sometimes considered a variant of niemann-pick disease. (12 Dec 1998) |
| pyrrol blue | C4OH3ON3O6Na;an acid triarylmethane dye employed as a vital dye and as an elastin stain. Synonym: Isamine blue. (05 Mar 2000) |
| sky blue | A pigment mixture of cobaltous stannate and calcium sulfate; used biologically as an injection mass. (05 Mar 2000) |
| nevus, blue | A benign nevus, usually solitary, representing a localised proliferation of dermal melanocytes, which is manifested by a dark blue to black, moderately firm, rounded, sharply defined nodular tumour composed of spindle-shaped melanocytes with slender cytoplasmic processes, occurring often in association with melanin-laden macrophages in a sclerotic dermis. It is also called dermal melanocytoma and jadassohn-tieche nevus. (12 Dec 1998) |
