At a concentration of 0.5 µg/ml, ethidium bromide is useful in agarose or acrylamide ges for band detection. It is used to detect as little as 10ng of nucleic acid. At high concentrations (0.5 - 1.0µg/ml), it may be used to facilitate purification of DNA in cesium chloride gradient.
For maximum convenience, AMRESCO offers ethidium bromide in various forms, including ready-to-use solutions and powerded forms. Each is packages in shatter-resistnat packaging for added safety. AMRESCO's ethidium bromide dropper bottle offers the ultimate convenience and saftey. Simply dispense one drop of ethidium bromide into 50ml of agarose gell or running buffer (TBE of TAE) or staining solution.
