GelRed™ is an ultra-sensitive, extremely stable and environmentally safe fluorescent nucleic acid dye designed to replace the highly toxic ethidium bromide (EtBr) for staining dsDNA, ssDNA or RNA in agarose gels or polyacrylamide gels. GelRed™ is far more sensitive than EtBr without requiring a destaining step. GelRed™ and EtBr have virtually the same spectra, so you can directly replace EtBr with GelRed™ without changing your existing imaging system.
GelRed™ can be used to stain dsDNA, ssDNA or RNA in agarose gels via either precast or post gel staining or can be used to stain polyacrylamide gels via post gel staining. GelRed™ is also compatible with downstream DNA manipulations such as restriction digest, sequencing, and cloning.
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, GelRed™ can be safely disposed of down the drain or in regular trash, providing convenience and reducing cost in waste disposal.
GelRed™ 10,000X solution in DMSO is for established users of GelRed™ in DMSO who do not wish to change their laboratory protocols. For new users, we recommend GelRed™ 10,000X in water (catalog # G-725), which eliminates the hazards of handling DMSO for even better safety. The performance and stability of GelRed™ 10,000X is comparable in both the water and DMSO formulations.
