GelRed™ is an ultra sensitive, extremely stable and environmentally safe fluorescent nucleic acid dye designed to replace the highly toxic ethidium bromide (EB) for staining dsDNA, ssDNA or RNA in agarose gels or polyacrylamide gels. GelRed™ is far more sensitive than EB without requiring a destaining step. GelRed™ and EB have virtually the same spectra, so you can directly replace EB with GelRed™ without changing your existing imaging system. A series of safety tests have confirmed that GelRed™ is noncytotoxic, nonmutagenic and nonhazardous at concentrations well above the working concentrations used in gel staining. As a result, working strength GelRed™ can be safely disposed of down the drain or in regular trash. Note that GelRed™ 10,000X in water (catalog no. 41003) is a newer, safer formulation and our recommeded format. We continue to offer GelRed™ 10,000X in DMSO (catalog no. 41002) for users who do not wish to change established protocols.
