Introduction High-quality buffers are an essential component of electrophoresis. They allow a current to flow through the sample and resist pH changes in the surrounding solution. The isoelectric point of the sample determines the buffer used. The most often used buffers for DNA electrophoresis are TAE (Tris-acetate-EDTA) and TBE (Tris-borate-EDTA). SDS (sodium dodecyl sulfate) is a […]
