Application

Ready for use in gel electrophoresis after dilution to working concentrations.
TBE running buffer is the most commonly used buffer for DNA and RNA polyacrylamide gel electrophoresis. TBE is used with non-denaturing or denaturing (7 M urea) gels. It is also routinely used for DNA automated sequencing gel. TBE can also be used for agarose gels but is not recommended for preparative gels for recovery of nucleic acids.
Dilution of the TBE stock concentrates to a 1× TBE running buffer results in a buffer containing 89 mM Tris-borate and 2 mM EDTA, pH 8.3. The 5× or 10× stocks may also be added to an acrylamide/bis-acrylamide stock solution for making the PAGE gel. Applied voltages of less than 5 V/cm (distance between the electrodes of the unit) are recommended for maximum resolution.

Preparation Note

Prepared with Biotechnology Performance Certified Trizma base (Product Code T6066) and Molecular Biology Reagents boric acid (Product Code B6768) and EDTA disodium salt (Product Code E5134).

Reconstitution

Produces a 5× concentrate (0.445 M Tris-borate, 10 mM EDTA, pH 8.3) after dissolving with the indicated amount of water.

Radiation-induced DNA double-strand break (DSB) repair can be tested by using pulsed-field gel electrophoresis (PFGE) in agarose-encapsulated cells. However, previous studies have reported that this assay is impaired by the spontaneous DNA breakage in this medium. We investigated the mechanisms...

Nanofluidics represents a promising solution to problems in fields ranging from biomolecular analysis to optical property tuning. Recently a number of simple nanofluidic fabrication techniques have been introduced that exploit the deformability of elastomeric materials like polydimethylsiloxane (PDMS). These techniques...
Protocols
TAE and TBE are both used as running buffers for nucleic acid electrophoresis but have some important differences. Review our recipes and video to give your application the best chance of success.
