GelRed is a fluorescent nucleic acid dye that could be used instead of ethidium bromide (EtBr), dsSafe, and others for staining dsDNA, ssDNA, or RNA in agarose gels or polyacrylamide gels. GelRed is more stable, more sensitive, and less toxic than EtBr (because of being cell membrane-impermeant) and doesn`t require a destaining step. GelRed has been validated for Southern blotting.
