| 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. (05 Mar 2000) |
| Orth's stain | <technique> A lithium carmine stain for nerve cells and their processes. (05 Mar 2000) |
| Taenzer's stain | <technique> An orcein solution used for staining elastic tissue. Synonym: Unna-Taenzer stain. (05 Mar 2000) |
| Takayama's stain | <technique> A stain containing pyridine, sodium hydrate, and dextrose; used for identification of blood stains; a drop added to a suspected blood stain results in the formation of haemochromogen crystals. (05 Mar 2000) |
| telomeric R-banding stain | <technique> A modified R-banding stain in which the telomeres become strongly stained and faint R-banding still occurs over the rest of the chromosomes; uses air-dried slides, aging for several days, and staining in hot phosphate-buffered Giemsa stain. (05 Mar 2000) |
| thioflavine T stain | <technique> A stain employed to detect amyloid, which induces specific yellow fluorescence; tissue sections are first put in alum-haematoxylin to quench nuclear fluorescence and then stained in thioflavine T. (05 Mar 2000) |
| Ehrlich's acid haematoxylin stain | <technique> An alum type of haematoxylin stain used as a regressive staining method for nuclei, followed by differentiation to required staining intensity; the solution may be allowed to ripen naturally in sunlight or partially oxidised with sodium iodate. (05 Mar 2000) |
| Ehrlich's aniline crystal violet stain | <technique> A stain for Gram-positive bacteria. (05 Mar 2000) |
| Ehrlich's triacid stain | <technique> A differential leukocytic stain comprised of saturated solutions of orange G, acid fuchsin, and methyl green. (05 Mar 2000) |
| Ehrlich's triple stain | <technique> A mixture of indulin, eosin Y, and aurantia. (05 Mar 2000) |
| Einarson's gallocyanin-chrome alum stain | <technique> A method for staining both RNA and DNA a deep blue; with proper controls, nucleic acid content of stained cells and nuclei may be estimated by cytophotometry; also useful for Nissl substance. (05 Mar 2000) |
| Tizzoni's stain | <technique> A stain used as a test for iron in tissue; the tissue is treated with a solution of potassium ferrocyanide and then with dilute hydrochloric acid; a blue colouration indicates the presence of iron. (05 Mar 2000) |
