Nucleic Acid Gel Electrophoresis and Blotting |
Nucleic acid electrophoresis uses a gel matrix to separate DNA and RNA fragments based on size and molecular weight. In blotting, DNA and RNA fragments, separated by electrophoresis, are transferred to a membrane matrix. Probes are then used to detect the presence of target sequences on the membrane matrix. Specific DNA and RNA sequences in a sample are detected by Southern and Northern blots, respectively. Nucleic acid electrophoresis and blotting are chief pillars supporting molecular biology research. Lay a solid foundation for your research with Thermo Fisher Scientific’s suite of products that aid nucleic acid electrophoresis and blotting.

Nucleic acid electrophoresis systems
Thermo Fisher Scientific offers traditional and precast gel nucleic acid electrophoresis systems. The precast E-Gel systems come with a gel running platform integrated with an imaging device. These systems are suitable for both standard and high-throughput electrophoresis. The traditional Owl systems are used for casting and running micro, mini, and wide gels.
E-Gel Precast Agarose Gel Electrophoresis System
The Invitrogen E-Gel precast agarose gel electrophoresis systems are bufferless agarose gel electrophoresis systems with ready-to-use precast agarose gel cassettes with in-gel stain. The E-Gel precast agarose electrophoresis system simplifies the electrophoresis workflow, and it is ideal for analyzing PCR products, restriction digests, and plasmid preparations.
Owl Electrophoresis Systems
Products for conventional horizontal (agarose) or vertical (polyacrylamide) gel electrophoresis including tanks, chambers, casters, plates, spacers, combs, power supplies, and other accessories.
