VWR® Agarose Gel Loading Dye, Ultra Pure Grade

Supplier: VWR

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.

Ethidium bromide (1 - 10 mg/ml) in aqueous solution

Supplier: VWR

Ethidium Bromide solution is a fluorescent stain for visualizing nucleic acids in solution or in electrophoresis gels. 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 10 ng of nucleic acid. At high concentrations (0.5 - 1.0 µg/ml), it may be used to facilitate purification of DNA in cesium chloride gradient.
