Blue Gel Loading Buffer with DNA Stain

Jena Bioscience Gel Loading Buffers with DNA Stain are formulated to facilitate loading of DNA samples into the wells of agarose and polyacrylamide gels. The loading buffer contains a green-fluorescent DNA stain specially developed for DNA analysis applications. The high quantum yield and excellent stability make the dye the ideal fluorophore for DNA staining applications and an excellent replacement for the widely used dye ethidium bromide. The buffers contain tracking dyes as indicator for DNA fragment migration. In addition, they contain glycerol to add density and EDTA to inhibit nuclease activities. The buffers are optimized for loading of DNA fragments in a size range of: Gel Loading BufferCat.
