41003-1 GelRed Nucleic Acid Gel Stain, 10,000X in water
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.
For detailed information, please visit the DNA Stain Technology page.
GelRed can be used to stain dsDNA, ssDNA or RNA in agarose gels via either precast or post gel staining. GelRed can also be used to stain dsDNA, ssDNA or RNA in polyacrylamide gels via post gel staining. GelRed is also compatible with downstream DNA manipulations such as restriction digest, sequencing, and cloning. For detailed protocols for use, please download the GelRed Product Information Sheet. Also see our GelRed and GelGreen Frequently Asked Questions (FAQs).
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. For detailed test results, you may download the GelRed/GelGreen Safety Report.
Biotium offers GelRed 10,000X solution in water, our latest formulation that eliminates the hazards of handling DMSO for better safety. We continue to offer GelRed 10,000X solution in DMSO (41002) for established users of GelRed in DMSO who do not wish to change their laboratory protocols. The performance and stability of GelRed 10,000X is comparable in both the water and DMSO formulations. For your convenience, we also offer ready-to-use GelRed 3X in water (41001) that can be directly used for post-electrophoresis gel staining. Also see GelGreen Nucleic Acid Gel Stain, a safer replacement for SYBR? gel stains, which is compatible with visible light excitation.

Please also see our EvaGreen? dye, a breakthrough nucleic acid dye ideally suited for quantitative real-time PCR (qPCR). By incorporating a smart “release-on-demand” DNA-binding technology, EvaGreen? has low PCR inhibition while exhibiting superior sensitivity. Similar to GelRed, EvaGreen? is non-toxic, non-mutagenic, and remarkably stable.
