How long as some one another sheet, it to be stained after electrophoresis; Adjust the ph of the solution to 5.3 ± 0.1, if necessary (solution a). Bromophenol blue powder and methanol. At neutral ph, the dye absorbs red light most strongly and transmits blue light. It is better to add dna gel loading dye directly to the pcr tubes containing our pcr amplicon. = 0.010 grams of bromophenol blue in 20 ml of water makes 0.05% (mass/volume) bromophenol blue. Agarose gel after coating, bromophenol blue acts as less staining protocol for bromophenol blue dna staining solution. The solution should be deep blue. 40%sucrose, or 15%ficoll, or 30%glycerol all in. A 10μl sample can be loaded into the agarose gel well.
Bromophenol's blue color is ph dependent: To prepare 10 ml of 6x dna loading dye, weigh out 25 mg bromophenol blue. Btb can be prepared by mixing 0.1 g (a pinch) of bromothymol blue powder in 10 ml of a 4% solution of sodium hydroxide. To prepare 10 ml of 6x dna loading dye, weigh out 25 mg bromophenol blue, 25 mg xylene cyanol ff, and 4 g ficoll 400. Dissolving 1kg of phenol red in 3l of glacial acetic acid; The dye is not very soluble. But your solution will be really blue. Weigh accurately 40 mg of bromophenol blue and pour it into a 100.00 ml volumetric flask containing 01.20 ml of 0.05n sodium hydroxide solution and 10.00 ml of 95% ethanol, warm it. The pka is about 4. Mix until all ingredients dissolve completely. 2) store at room temperature.
