Properties: blue black or dark brown powder. Soluble in water (blue-black), ethanol (dark blue) and cellosolve (diethanol-ethyl ether), slightly soluble in acetone, insoluble in other organic solvents. In case of concentrated sulfuric acid, it is blue-green, which is diluted into dark green and blue precipitate. In case of concentrated nitric acid, it is dark green solution. Blue solution with 10% sodium hydroxide solution showing red fluorescence. Concentrated hydrochloric acid is added to the aqueous solution to produce a green-blue precipitate, and concentrated sodium hydroxide solution is added to form a blue precipitate. When dyeing, it encounters copper; iron ions, the color of the former changes slightly, the latter is slightly greenish Use: Biochemical research. Electrophoresis reagent for staining proteins on polyacrylamide gel, agarose gel and nitrocellulose membrane. After electrophoresis, it is recommended to fix the protein on the gel. The glue is stained with 0.1% amino black 10B in 7% (v / v) acetic acid solution for at least 2 hours, and then decolorized with 7% (v / v) acetic acid solution. The detection sensitivity is about 20% of the Coomassie Brilliant Blue R250. Redox indicator storage: RT
