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.
GelRed® 3X in water (catalog no. 41001) is ready-to-use for post-electrophoresis gel staining, and is supplied in a 4L Cubitainer®.
