General description

Tris, borate, and ethylenediaminetetraacetic (TBE) buffer is routinely used to conduct DNA and RNA agarose gel electrophoresis. It comprises a weak acid in neutral and anionic forms (e.g., COOH and COO- species) and a weak base, Tris, which is either in neutral or cationic forms (Tris-NH2 and Tris-NH3+). These ions buffer the pH, maintain a low conductivity medium, and transfer the electrical current. Ethylenediaminetetraacetic (EDTA) is used to chelate Mg2+ ions and inactivate the potential DNA nucleases. TBE is also used to perform a good resolution of DNA fragments that slightly enhances the separation of smaller fragments. It also protects nucleic acids from enzymatic degradation.
