para-amino salicylic acid
| Stirling's modification of Gram's stain | <technique> A stable aniline-crystal violet stain. (05 Mar 2000) |
|---|---|
| neutral stain | <technique> A compound of an acid stain and a basic stain, such as the eosinate of methylene blue, in which the anion and cation each contains a chromophore group. Synonym: salt dye. (05 Mar 2000) |
| Nicolle's stain | <technique> For capsules, stain in a mixture of a saturated solution of gentian violet in alcohol-phenol. (05 Mar 2000) |
| ninhydrin-Schiff stain | <technique> For proteins, proteins are revealed by using ninhydrin or alloxan to produce aldehydes from primary aliphatic amines by oxidative deamination; the aldehydes are shown by reaction with Schiff's reagent. (05 Mar 2000) |
| Nissl's stain | <technique> A method for staining nerve cells with basic fuchsin, a method for staining aggregates of rough endoplasmic reticulum and ribosomes in neuronal cell bodies and dendrites with basic dyes such as cresyl violet (or cresyl echt violet), thionine, toluidin blue O, or methylene blue. (05 Mar 2000) |
| Noble's stain | <technique> A basic fuchsin-orange G staining technique for detection of viral inclusion bodies in fixed tissues. (05 Mar 2000) |
| Sudan stain | <chemical, investigation> Histochemical stains used for lipids. (18 Nov 1997) |
| 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) |
