| nuclear stain | <technique> A stain for cell nuclei, usually based on the binding of a basic dye to DNA or nucleohistone. (05 Mar 2000) |
| Da Fano's stain | <technique> A silver stain that produces a blackening of Golgi elements after tissues are fixed in a mixture of nitrate and formalin. (05 Mar 2000) |
| Dane's stain | <technique> A stain for prekeratin, keratin, and mucin which employs haemalum, phloxine, Alcian blue, and orange G; nuclei appear orange to brown, acid mucopolysaccharides pale blue, and keratins orange to red-orange. (05 Mar 2000) |
| DAPI stain | <technique> A sensitive fluorescent probe for DNA, 4'6-diamidino-2-phenylindole-2HCl, used in fluorescence microscopy to detect DNA in yeast mitochondria, chloroplasts, viruses, mycoplasma, and chromosomes; DNA is visualised in vitally stained living cells and after cells are fixed in formaldehyde. (05 Mar 2000) |
| supravital stain | <technique> A procedure in which living tissue is removed from the body and cells are placed in a nontoxic dye solution so that their vital processes may be studied. (05 Mar 2000) |
| diazo stain | <technique> For argentaffin granules, in enterochromaffin cells, a variety of diazonium salts are used to blacken the cells. (05 Mar 2000) |
| Dieterle's stain | <technique> Stain used to demonstrate spirochetes and Leishman-Donovan bodies; employs silver nitrate and uranium nitrate. (05 Mar 2000) |
| differential stain | <technique> A dye used to colour one portion of a tissue or cell which remained unaffected when the other part was stained by a dye of different colour. Synonym: differential stain. (05 Mar 2000) |
| double stain | <technique> A mixture of two dyes, each of which stains different portions of a tissue or cell. (05 Mar 2000) |
| immunofluorescent stain | <technique> Stain resulting from combination of fluorescent antibody with antigen specific for the antibody portion of the fluorochrome conjugate. (05 Mar 2000) |
| India ink capsule stain | <technique> A negative stain for crystal bacteria in which cells appear purple (Gram's crystal violet) and the capsules appear clear against a dark background. (05 Mar 2000) |
| quinacrine chromosome banding stain | q-banding stain |
| intravital stain | <technique> A stain which is taken up by living cells after parenteral administration, e.g., intravenously or subcutaneously. (05 Mar 2000) |
| iodine stain | <technique> A stain to detect amyloid, cellulose, chitin, starch, carotenes, and glycogen, and to stain amoebas by virtue of their glycogen; faeces and other wet preparations are stained directly with Lugol's iodine solution; smears are treated with Schaudinn's fixative and then stained with alcoholic iodine, followed by Heidenhain's iron haematoxylin.
