| ethidium bromide | <chemical, molecular biology> A dye that intercalates into DNA and to some extent RNA. Intercalation into linear DNA is easier than into circular DNA and the addition of ethidium bromide to DNA prior to ultracentrifugation on a caesium chloride gradient is much used to separate nuclear and mitochondrial or plasmid DNA for analytical purposes. Because less intercalates into the circular DNA, the density remains higher. (18 Nov 1997) |
| 2-hydroxy-5-nitrobenzyl bromide | <chemical> 2-(bromomethyl)-5-nitrophenol. A chemical reagent that reacts with and modifies chemically the tryptophan portion of protein molecules. Used for 'active site' enzyme studies and other protein studies. Sometimes referred to as koshland's reagent. Pharmacological action: indicators and reagents. Chemical name: Phenol, 2-(bromomethyl)-4-nitro- (12 Dec 1998) |
