Agarose Gel Electrophoresis

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. (Learn more: Nucleic acid electrophoresis education.)

We offer convenient reagents for agarose gel electrophoresis including hassle-free precast Invitrogen E-Gel agarose gels, safe and sensitive DNA gel stains, DNA ladders, and UltraPure reagents to cast agarose gels yourself.

Which DNA gel is right for you?

Electrophoresis systems

E-Gel Precast Agarose Gel Systems

Fast, bufferless agarose electrophoresis with ready-to-use cassettes precast with agarose, electrodes and in-gel stain. Ideal for analyzing PCR products, restriction digests and plasmid preparations.

Owl Gel Electrophoresis Systems

Thermo Scientific Owl gel electrophoresis systems offer horizontal (agarose) or vertical (polyacrylamide) gel electrophoresis of nucleic acids and protein using tanks, chambers, casters, plates, spacers, combs, power supplies, and other accessories.

Agarose and reagents

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.

TopVision Agarose

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

DNA Ladders and markers

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 is available in the ready-to-use Invitrogen TrackIt and E-Gel formats, including the 1 Kb DNA Ladder and the 100 bp DNA Ladder.

Thermo Scientific DNA Ladders

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

DNA Stains

We've developed a range of DNA stains, including SYBR Safe DNA gel stain and ethidium bromide. Invitrogen 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 products

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.
