Description_x000D_ Packaging_x000D_ 1 L in poly bottle_x000D_ Application_x000D_ Ready for use in gel electrophoresis after dilution to working concentrations._x000D_ 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._x000D_ Packaging_x000D_ Packaged in plastic bottles large enough to contain the concentrate after reconstitution._x000D_ Preparation Note_x000D_ Prepared with Biotechnology Performance Certified Trizma base (T6066) and Molecular Biology Reagent EDTA disodium salt (E5134). Solutions also contain acetic acid (A6283); powdered blend contains Trizma acetate (T1258)._x000D_ Reconstitution_x000D_ Produces a 10× concentrate (0.4 M Tris-acetate, 10 mM EDTA, pH 8.3) after dissolving with the indicated amount of water.
