Ethidium Bromide solution is a fluorescent stain for visualizing nucleic acids in solution or in electrophoresis gels. The solution is provided at a concentration of 0.625mg/mL. A final working concentration of 0.5g/mL is easily obtained by adding 1 drop of solution to 50 mL of molten agarose, running buffer or staining buffer. Ethidium Bromide solution in dropper bottles may be stored at room temperature for up to 1 year.

VWR® electrophoresis gel loading dyes are tested for contaminating DNase, RNase, and protease activity and are sterile filtered for long shelf life and stability. In addition, all dyes are function tested and do not interfere with sample migration. Their ready-to-use format eliminates exposure to potentially irritating and harmful powdered dyes. Agarose Gel Loading Dye is designed to optimize loading nucleic acids in acrylamide and agarose gels by imparting color to the sample to ensure efficient sample distribution into each well. Its blend of three tracking dyes make estimating sample migration simple and reliable.
