Super GelRed® is a sensitive, 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. Super GelRed® and EtBr have virtually the same spectra , so you can directly replace EtBr with Super GelRed® without changing your existing imaging system. In addition, Super GelRed® is far more sensitive than EtBr .
