Electrophoresis buffers are used to provide ions that carry the electric current and to maintain the pH at a relatively constant value. The buffer controls the ionization state of the molecules moving through the gel matrix. There are a number of buffers used for electrophoresis. The most common buffers for nucleic acids are Tris /acetate/EDTA (TAE) and Tris/Borate/EDTA (TBE). Common electrophoresis buffers for PAGE include MES and Tris-glycine. Alfa Aesar offers a wide range of buffers for electrophoresis including sample, loading, and running buffers.
