Description:This historic image from 1963 depicts a disassembled starch block electrophoresis apparatus. See PHIL 12023 for an assembled view of this apparatus.
Electrophoresis employs a uniformly maintained electric field, which influences particles suspended in a fluid through which this electric field is passed. It is a process, which is still widely used today when it is necessary to separate different molecules from one another based on their unique surface charge, and their size. The uniformly dispersed electric field influences the movement of the molecules being separated, and the porous channels throughout the matrix allows smaller molecules to move more readily through the medium than larger molecules. This phenomenon of molecular migration, is measured base on time, thereby, giving the scientist an appreciation for the molecular components of a given substance being analyzed.
