TBE buffer (Tris-Borate-EDTA), 10x Solution: TBE buffer is commonly used in all DNA electrophoresis applications (both for acrylamide and for agarose gels).
In general, TBE buffer offers better resolution of 0.1 to 3 kb fragments, whereas TAE (Tris-Acetate-EDTA) buffer provides better resolution of fragments greater than 4 kb.
Furthermore, TBE is better suited for high-voltage (>150V) electrophoresis because of its higher buffering capacity and lower conductivity than TAE1.
BIO BASIC INC. offers TBE in a number of different formats.
10X liquid concentrate can be used to easily prepare a 1X working solution by diluting with distilled, deionized water.
10X TBE Powder allows for the stable storage of the pre-mixed powder form that can be dissolved in distilled, deionized water to yield 1 liter each of 10X TBE buffer solution.
