GelGreen® Nucleic Acid Gel Stain
GelGreen® is a sensitive, non-mutagenic and environmentally safer green fluorescent DNA gel stain.
Comparison of ethidium bromide (EtBr) and GelRed® in precast gel staining (left) and comparison of GelGreen® and SYBR Safe in post-electrophoresis staining (right). Two-fold serial dilutions of 1 kb Plus DNA Ladder (Invitrogen) were loaded in the amounts of 200 ng, 100 ng, 50 ng and 25 ng from left to right and separated on 1% agarose TBE gels. For gels prestained with EtBr or GelRed®, gels were imaged with a 300 nm transilluminator and photographed with an EtBr filter. For gels post-stained with SYBR® Safe or GelGreen®, gels were imaged with a 254 nm UV transilluminator and photographed with a SYBR® filter.Product Description
GelGreen® is a highly sensitive, non-toxic green fluorescent nucleic acid dye designed for staining DNA in agarose gels.
- Non-mutagenic, for safer handling and easy disposal
- Much more sensitive than EtBr, SYBR® Safe, and others
- Extremely stable for storage at room temperature & microwaving in agarose
- Simple precast or post-electrophoresis gel staining
- Use with UV transilluminator or blue light gel reader
- Compatible with downstream gel purification, restriction digest, sequencing and cloning
GelGreen®: A Superior Green Fluorescent DNA Gel Stain
GelGreen® is far more sensitive than SYBR® Safe. Unlike SYBR® dyes, which are known to be unstable, GelGreen® is very stable, both hydrolytically and thermally. GelGreen® is compatible with a 254 nm UV transilluminator, and can be imaged using a SYBR® Green or GelStar® filter. It also can be used with visible blue light excitation imagers (blue LED light box or Dark Reader®). With blue light illuminators, researchers can avoid exposure to UV irradiation for themselves and their DNA samples, for a safer work environment and higher cloning efficiency.
Non-Mutagenic and Safer for the Environment
A series of safety tests have confirmed that GelGreen® is noncytotoxic, nonmutagenic and nonhazardous at concentrations above those used for gel staining. As a result, working strength GelGreen® 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 a complete GelRed®/GelGreen® Safety Report.
How Safe is Your Gel Stain?
Many so-called “safe” DNA dyes like SYBR® Safe, Midori Green, GreenSafe, SafeView™, and RedSafe™ not only have low sensitivity, but also readily penetrate living cells to bind DNA, and some are cytotoxic. Unlike these dyes, GelGreen® is cell membrane-impermeant, so it cannot enter living cells to interact with their DNA. See our Gel Stains Comparison Flyer or Gel Stains Comparison White Paper for details.
Your Top GelRed® and GelGreen® Questions Answered
Choose the Right Stain for Your Application
For new users, we recommend GelGreen® 10,000X in water (catalog no. 41005), our latest formulation that eliminates the hazards of handling DMSO for better safety. We continue to offer GelGreen® 10,000X solution in DMSO for established users who do not wish to change their existing laboratory protocols. We also offer GelGreen® Agarose for convenient and safer preparation of precast gels. Also see GelRed® Nucleic Acid Gel Stain, our safer replacement for ethidium bromide. GelGreen® can be used to stain ssDNA and RNA, but we recommend GelRed® for this application because it is five times more sensitive for single stranded nucleic acids than GelGreen®. Also learn about DNAzure® 2.0 Visible Blue DNA Gel Stain Kit for visualizing DNA bands with the naked eye with no need for a UV light source. DNAzure® 2.0 delivers excellent sensitivity, detecting as little as ~1 ng of double-stranded DNA in both agarose and polyacrylamide gels.

| DNA prestaining with GelRed® Prestain Plus 6X DNA Loading Dye | GelRed® loading buffer is added directly to the DNA sample before loading | • Fast & simple: one-step sample loading & DNA staining • Less concentrated dye for safer handling • Can re-run a gel to use empty lanes | • Not recommended for PAGE, DGGE, EMSA, or PFGE gels • Dye may cause band migration issues when loading larger amounts of DNA (more than ~100 ng/band), or for some restriction digests | • Routine agarose gels • Recommended loading 50-200 ng ladder or 2-5 uL PCR product ( ~100 ng/band or less) |
| Precast staining with GelRed® 10,000X in water or GelGreen® 10,000X in water | GelRed® or GelGreen® is mixed with molten agarose before gel casting | Familiar protocol, rapid results | ||
| Precast staining with GelRed® Agarose LE or GelGreen® Agarose LE | Agarose is supplied pre-coated with GelRed® or GelGreen®, just dissolve, heat, and pour | Safer & more convenient, no need to handle concentrated dye | ||
| Post-electrophoresis staining with GelRed® 10,000X in water or GelGreen® 10,000X in water - or - GelRed® 3X in water | No fluorescent dye is added to the gel, it is stained in 3X GelRed® or 3X GelGreen® solution after electrophoresis | • Most accurate sizing/sharpest bands • Staining solution can be re-used • Enhance sensitivity by adding NaCl | Extra staining step (up to 30 minutes) after electrophoresis (some customers report good results after only 5 minutes if dye is not reused) | • Highly accurate band sizing • Gels with more than ~100 ng DNA per band • Analyzing restriction digests |
| Post-electrophoresis staining with DNAzure® 2.0 Visible Blue DNA Gel Stain Kit | No fluorescent dye is added to the gel, it is stained in DNazure® 2.0 solution and then exposed to a bright light source to generate visible blue DNA bands.
