Precast GelRed® Agarose Gels, 1% Agarose/TAE

Ready-to-use 1% agarose/TAE gels precast with GelRed® Nucleic Acid Gel Stain. The gels are suitable for visualizing 250-12,000 bp DNA fragments.

Technology

Nucleic Acid Gel Stains

Product Description

Precast GelRed® Agarose Gels are ready-to-use gels intended for DNA gel electrophoresis. The 1% agarose gels were cast in TAE buffer and contain highly sensitive GelRed® Nucleic Acid Gel Stain, saving a significant amount of time by eliminating the need for casting gels.

  • Ready-to-use 1% agarose/TAE gels precast with GelRed®
  • Saves time by eliminating the need for casting gels
  • Ultra-sensitive GelRed® for brighter DNA staining than EtBr
  • GelRed® is a non-mutagenic, non-toxic replacement for hazardous EtBr
  • Replaces EtBr with no change to equipment or optical settings
  • Suitable for visualizing 250-12,000 bp DNA fragments
  • Gels available with 8 or 18 wells and sold in packs of 10 gels

Biotium offers 1X TAE (1 L) Buffer Powder Packets (Cat. No. 22031) that are suitable for use with Precast GelRed® Agarose TAE Gels.

GelRed®: A Superior Replacement for EtBr

GelRed® and ethidium bromide (EtBr) have very similar excitation and emission wavelengths, so you can directly replace EtBr with GelRed® without changing your existing imaging system. In addition, GelRed® is far more sensitive than EtBr. Staining nucleic acids with GelRed® is compatible with downstream applications such as sequencing and cloning. GelRed® can be removed from DNA using a gel extraction kit, or by phenol/chloroform extraction followed by ethanol precipitation. To learn more, learn more about GelRed® or read our GelRed® FAQs.

Non-Mutagenic and Safer for the Environment

GelRed® 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. GelRed® successfully passed environmental safety tests in compliance with CCR Title 22 Hazardous Waste Characterization, under which GelRed® is classified as non-hazardous waste. See the GelRed® and GelGreen® Safety Report.

• 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
