Introduction to Preparative Electrophoresis

Electrophoresis techniques have been primarily developed for analytical purposes— to investigate the characteristics of the molecules in the sample of interest. The techniques can be modified to serve a preparative purpose, in which a large amount of a specific molecule can be obtained at the end of an electrophoresis run. Preparative electrophoresis uses the same principles as analytical electrophoresis but
