| neutral oxide | An oxide that is neither an acid nor a base; e.g., water (hydrogen oxide, H2O). Synonym: indifferent oxide. (05 Mar 2000) |
|---|---|
| neutral point | The point at which a solution is neither acid nor alkaline (pH 7 at 22캜 for aqueous solutions). (05 Mar 2000) |
| neutral protease | <enzyme> Protease that is optimally active at neutral pH: See: proteases. (18 Nov 1997) |
| neutral reaction | PH of 7.00; H+ and OH- ion concentrations equal at 10-7 m at 22캜. Compare: dissociation constant of water. (05 Mar 2000) |
| neutral red | <chemical> 3-amino-7-dimethylamino-2-methylphenazine hydrochloride. A vital dye used as an indicator and biological stain. Various adverse effects have been observed in biological systems. Pharmacological action: dyes, indicators and reagents. Chemical name: 2,8-Phenazinediamine, N8,N8,3-trimethyl-, monohydrochloride (12 Dec 1998) |
| neutral spirits | Spirits distilled from suitable raw materials, are 95% ethanol (v/v) that is, at least 190 proof when distilled. Used for blending with straight whiskey and for making gin, cordials, liqueurs, and vodka. See: alcohol. Proof spirit, dilute alcohol, specific gravity 0.920, containing 49.5% by weight (57.27% by volume) of C2H5OH at 15.56캜. Originally in Great Britain it was the weakest alcohol that would permit ignition of gunpowder moistened with it. British proof spirit has a specific gravity of 0.9198 and contains 49.2% C2H5OH by weight, or 57.1% by volume at the temperature of 10.56캜. (05 Mar 2000) |
| neutral stimulus | When paired with the unconditioned stimulus in simultaneous presentation to an organism, capable of eliciting a given response. (05 Mar 2000) |
| neutral zone | In dentistry, the potential space between the lips and cheeks on one side and the tongue on the other; natural or artificial teeth in this zone are subject to equal and opposite forces from the surrounding musculature. (05 Mar 2000) |
| day neutral plant | <botany> Plants that flower regardless of day length. (09 Oct 1997) |
| lens neutral proteinase | <enzyme> Degrades alpha 2-crystallin; requires ca and mg; cleaves phe-ser bond in bradykinin; similar enzyme found in human lung Registry number: EC 3.4.24.5 Synonym: neutral proteinase 24.5 (26 Jun 1999) |
| Abbott's stain | <technique> Spores are stained blue with alkaline methylene blue; bodies of the bacilli become pink with eosin counterstain. (05 Mar 2000) |
| aceto-orcein stain | <technique> A stain used for chromosomes in air-dried or squashed cytologic material. (05 Mar 2000) |
| acid-fast stain | <technique> A staining technique used to determine the cell wall property of a microorganism. After stained with dye such as hot carbolfuschin, an acid-fast organism, (for example Mycobacterium species) will retain the colour in its cell wall after being washed with acid-alcohol. (13 Nov 1997) |
| acid stain | <technique> A dye in which the anion is the coloured component of the dye molecule, e.g., sodium eosinate (eosin). (05 Mar 2000) |
| Ag-AS stain | <technique> A stain for the acid protein component of nucleolar regions which are active or which were transcriptionally active in the preceding interphase; uses silver nitrate, ammoniacal silver, and formalin. Synonym: Ag-AS stain. (05 Mar 2000) |
