Prioritize Safety in Your DNA Gel Electrophoresis
Safer, Sensitive & Economical GelRed®/GelGreen®
Although ethidium bromide (EtBr) has been the predominant dye for nucleic acid staining, its low sensitivity and high mutagenic properties make it suboptimal for research or for educational laboratories. In contrast, our nontoxic GelRed® and GelGreen® fluorescent agarose gel stains are sensitive and significantly safer alternatives for DNA gel staining.
