Agarose gel electrophoresis remains the most widely used technique for separating nucleic acid fragments because it is a simple technique that is nontoxic and offers a broad separation range. The size of the gel pores can be controlled by simply adjusting the agarose concentration to prepare gels appropriate for the separation of a wide range of different-size nucleic acid molecules. The migration of nucleic acids in agarose gels is also affected by the choice of running buffer and the applied voltage.

We offer convenient reagents for agarose gel electrophoresis including hassle-free precast E-Gel™ agarose gels, ready-to-use ReadyPouch™ Agarose Gel in a microwavable pouch, safe and sensitive DNA gel stains, DNA ladders, and UltraPure™ reagents to cast agarose gels yourself.

E-Gel Precast Agarose Gel Systems

E-Gel® system  

The E-Gel system is a bufferless system for agarose gel electrophoresis, viewing, and documentation. Samples are run in E-Gel pre-cast agarose gels that include electrodes, and are packaged in a dry, disposable, UV-transparent cassette. E-Gel gels are run in a base that includes a combined electrophoresis chamber and power supply. The precast agarose gels contain SYBR™ Safe stain, ethidium bromide, proprietary fluorescent DNA stain, or no DNA gel stain.

  • Offers fast, safe, consistent, high-resolution electrophoresis
  • Eliminates the need to prepare agarose gels and buffers, and to stain gels
  • Compatible with most robotic systems for high-throughput electrophoresis

Agarose and Reagents

ReadyPouch™ Agarose Gels  

ReadyPouch Agarose Gels

Convenient option for preparing gels, ReadyPouch Agarose Gels are ideal for analysis and recovery of DNA for routine applications.

  • Easy-to-use, microwave-safe pouch
  • Eliminates the risks of agarose boil-overs
  • Clear gel for improved visualization
  • Improved resolution of very large and small fragments

UltraPure Agarose and Reagents  

We've formulated a wide range of UltraPure agarose products for preparing your own gels for nucleic acid electrophoresis. All UltraPure reagents are made from the highest purity biochemicals for maximum reliability and superior performance.

  • Low electroendosmosis to minimize internal convection and band spreading during electrophoresis, resulting in sharp band resolution
  • No detectable DNase or RNase activity

Thermo Scientific™ TopVision™ Agarose

Available in both powder and tablet formats, TopVision™ agarose provides excellent gel transparency and low DNA/RNA binding.

DNA Ladders and Markers

DNA Ladders and Markers  

Invitrogen DNA ladders and markers

We offer a broad selection of DNA ladders and markers ranging from 10 bp to 50 Kb for accurate analysis of linear double-stranded DNA in agarose gels. A variety of these ladders are available in the ready-to-use TrackIt™ and E-Gel formats, including our popular 1 Kb Plus DNA Ladder and 100 bp DNA Ladder.


Thermo Scientific™ DNA Ladders

Our broad range of products includes GeneRuler™ DNA ladders that are ideal for sizing and in-gel DNA quantification of a wide range of double-stranded DNA fragments.

DNA Stains

SYBR® Safe DNA gel stain   We've developed a range of DNA stains, including SYBR Safe DNA gel stain and ethidium bromide. SYBR Safe DNA gel stain is a superior DNA stain that is nontoxic and nonmutagenic, yet has similar DNA detection sensitivity as ethidium bromide.

Agarose Gel Extraction Kits

Agarose Gel Extraction Kits Easily purify DNA fragments from agarose gels, in less than 30 minutes. Isolated DNA is free of proteins, dye, and agarose, and is ready to use for a variety of applications, including DNA sequencing, PCR, in vitro transcription, restriction mapping, cloning, and labeling.
