Prioritize safety in your DNA Gel Electrophoresis

GelRed® & GelGreen® are safer, sensitive, and economical.

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.

To learn more, visit the GelRed® and GelGreen® technology page.

Prepare precast gels more safely with ultrapure molecular biology grade agarose pre-coated in our GelRed® and GelGreen®.

Our GelGreen® and GelRed® Agarose LE offer an ultra-pure molecular biology grade agarose that comes pre-coated with either GelGreen® Nucleic Acid Gel Stain or GelRed® Nucleic Acid Gel Stain, ensuring maximum safety and ease of use, especially for beginners and students. The dye already incorporated into the agarose eliminates the need to handle concentrated fluorescent dye solutions, significantly enhancing safety measures. These pre-coated agarose formats can be used with TAE or TBE buffers for gel concentrations ranging from 0.8% to 2%.

GelRed® & GelGreen® do not readily penetrate living cells.

HeLa cells were incubated for 30 minutes at 37°C with 1X SYBR® Safe, GelRed®, or GelGreen®. SYBR® Safe rapidly bound to DNA in live cells resulting in bright green nuclear staining. GelRed® and GelGreen® were unable to bind DNA in live cells, shown by the absence of fluorescence.
