Application

Ready for use in gel electrophoresis after dilution to working concentrations.
TAE running buffer is the most commonly used buffer for DNA agarose gel electrophoresis but is also used for non-denaturing RNA agarose gel electrophoresis. Double-stranded DNA tends to run faster in TAE than in other buffers but can also become exhausted during extended electrophoresis. Buffer circulation or buffer replacement during extended electrophoresis can remedy the lower buffering capacity. Dilution of the concentrated TAE buffer produces a 1× TAE buffer with 40 mM Tris-acetate and 1 mM EDTA, pH 8.3. The 1× TAE buffer is used both in the agarose gel and as a running buffer. Applied voltages of less than 5 V/cm (distance between the electrodes of the unit) are recommended for maximum resolution.

Packaging

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.

Questions

  1. Good day. I'm interested in some information about the TAE buffer, MDL number T4038-1L. What kind of water should be used for preparation, and how long/under what conditions can the already prepared buffer be stored?

    1 answer
    1. This product should be reconstituted using at least deionized water for electrophoresis applications. The use of deionized double-distilled water is typical. Should RNase, DNase, or Protease be of concern, prepared and tested products, such as W4502, are also available.
