| Eranko's fluorescence stain | <technique> Exposure of frozen sections to formaldehyde which produces a strong yellow-green fluorescence from cells containing norepinephrine. (05 Mar 2000) |

| trypsin G-banding stain | <technique> A unique chromosome staining technique, used in human cytogenetics to identify individual chromosomes, which produces characteristic bands. It utilises acetic acid fixation, air drying, denaturing chromosomes mildly with proteolytic enzymes, salts, heat, detergents, or urea, and finally Giemsa stain; chromosome bands appear similar to those fluorochromed by Q-banding stain. Synonym: Giemsa chromosome banding stain. (05 Mar 2000) |
| Jenner's stain | <technique> A methylene blue eosinate similar to Wright's stain but differing in not using polychromed methylene blue; used for staining of blood smears. (05 Mar 2000) |
| Kasten's fluorescent Feulgen stain | <technique> A fluorescent modification of the Feulgen stain, utilizing any one of a variety of fluorescent basic dyes to which SO2 is added; the brilliant fluorescence makes this method unusually sensitive and adaptable to cytofluorometric quantification of DNA. (05 Mar 2000) |
| Kasten's fluorescent PAS stain | <technique> A fluorescent modification of the periodic acid Schiff stain for polysaccharides which uses one of Kasten's fluorescent Schiff reagents. (05 Mar 2000) |
| Ziehl-Neelsen stain | <technique> A method for staining acid-fast bacteria using Ziehl's stain, decolorizing in acid alcohol, and counterstaining with methylene blue; acid-fast organisms appear red, other tissue elements light blue; a modification of this stain is also used for Actinomycetes and Brucella. (05 Mar 2000) |
| Ziehl's stain | <technique> A carbol-fuchsin solution of phenol and basic fuchsin used to demonstrate bacteria and cell nuclei. (05 Mar 2000) |
| Kinyoun stain | <technique> A method for demonstrating acid-fast microorganisms, using carbol fuchsin, acid alcohol, and methylene blue; acid-fast microorganisms appear red against a blue background. (05 Mar 2000) |
| Kleihauer's stain | <technique> A combination of aniline blue and Biebrich scarlet red used for detection of foetal cells in the maternal blood. (05 Mar 2000) |
| Klinger-Ludwig acid-thionin stain | <technique> For sex chromatin, a method using a preliminary acid treatment on buccal smears, prior to staining with buffered thionin, to differentiate Barr body. (05 Mar 2000) |
| Kluver-Barrera Luxol fast blue stain | <technique> In combination with cresyl violet, a stain useful for demonstrating myelin and Nissl substance. (05 Mar 2000) |
| uranyl acetate stain | <technique> A stain used in electron microscopy; uranyl acetate binds specifically to nucleic acids but selectively tends to be abolished by osmium fixation; proteins are well stained, but cytomembranes are poorly stained. (05 Mar 2000) |
| urate crystals stain | <technique> A stain using silver methenamine to detect crystals, which polarise light in contrast with calcium crystals; useful in diagnosing gout and kidney infarcts resulting from uric acid build-up. (05 Mar 2000) |
| 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) |
| Kronecker's stain | <technique> A 5% sodium chloride stain rendered faintly alkaline with sodium carbonate, used in the examination of fresh tissues under the microscope. (05 Mar 2000) |
