Product Description

GelGreen® Agarose LE is our ultra-pure molecular biology grade LE agarose pre-coated with GelGreen® Nucleic Acid Gel Stain. With GelGreen® Agarose, there is no need to handle concentrated fluorescent dye while preparing your gel, for greater convenience and safety.

  • Non-toxic GelGreen® DNA dye is already in the agarose
  • No need to handle concentrated dye solutions, for enhanced safety
  • Use with TAE or TBE for 0.8% to 2% gels
  • Low EEO, ultrapure molecular biology grade agarose
  • Compatible with blue light illuminators

GelGreen® Agarose LE has low electroendosmosis (EEO) for high electrophoretic mobility. This agarose has excellent performance for analytical or preparative nucleic acid electrophoresis and blotting. It is suitable for preparing 0.8%-2% gels in TAE or TBE buffer. In a 1% GelGreen® Agarose gel, the final GelGreen® concentration is 1X, just like in our standard precast protocol. GelGreen® Agarose also gives excellent results at percentages between 0.8% (0.8X GelGreen®) up to 2% (2X GelGreen®).

GelGreen®: A Superior Green Fluorescent Gel Stain

GelGreen® is a sensitive, stable and environmentally safe green fluorescent nucleic acid dye specifically designed for gel staining. 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® has UV absorption between 250 nm and 300 nm and a strong absorption peak centered around 500 nm. Thus, GelGreen® is compatible with UV transilluminators or blue light illuminators (like the 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.

Gel staining with GelGreen® is compatible with downstream applications such as sequencing and cloning. GelGreen® can be removed from DNA using a gel extraction kit, or by phenol/chloroform extraction followed by ethanol precipitation. GelGreen® can be used to stain dsDNA, ssDNA or RNA, however GelRed® is much more sensitive for staining single-stranded nucleic acids than GelGreen®. To learn more about GelGreen®, see the GelRed® & GelGreen® technology page, or FAQs (below).

Non-Mutagenic and Safer for the Environment

GelGreen® was subjected to a series of tests at Biotium and by three independent testing services to assess the dye's safety for routine handling and disposal. Test results confirm that the dye is impenetrable to both latex gloves and cell membranes. The dye is non-cytotoxic and non-mutagenic at concentrations well above the working concentrations used in gel staining. Using GelGreen® Agarose further minimizes risk by avoiding the need to handle concentrated dye solution. GelGreen® successfully passed environmental safety tests in compliance with CCR Title 22 Hazardous Waste Characterization, under which GelGreen® is classified as non-hazardous waste. See the GelRed® and GelGreen® Safety Report.

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 KitNo 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.

We recommend the Glo-Plate™ White Photoactivation Device as a light source for developing DNAzure® 2.0-stained gels		• Allows visualization of DNA bands by the naked eye, no need for a UV light source

• Detect as little as ~1 ng DNA

• Stained bands are stable in gel for weeks

• Also emits near-IR fluorescence (~700 nm) for detection on near-IR imaging systems		Extra staining step (up to 30 minutes) followed by a light exposure step (up to 30 minutes) to generate visible blue DNA bands

• Routine DNA agarose gels

• Visualizing gels without the UV light or expensive imaging systems

• Recommended loading 50-200 ng DNA per lane
Post-electrophoresis staining of PAGE gels using PAGE GelRed® 10,000X or 1X in waterNo fluorescent dye is added to the gel, it is stained in 1X PAGE GelRed® solution after electrophoresis• Formulated for efficient penetration and staining of polyacrylamide gels

• Like the classic GelRed®, it is safe and environmentally friendly		Extra staining step of approx. 30 minutes after electrophoresisStaining of nucleic acids in PAGE gels
