Electrophoresis is used to study the properties of charged species and also as a separating technique. As an analytical tool, it is simple, rapid and highly sensitive. Electrophoresis, which simply means to move particles through a liquid or gel by electromotive force, allows for proteins and nucleic acids to migrate in response to an electric field. Their rate of migration depends on the strength of the electric field, their net charge, the size and shape of the molecules, the viscosity and temperature of the medium in which the molecules are moving, and on the ionic strength of the buffer used. Most electrophoresis is done in the presence of support matrices. Polyacrylamide and agarose are commonly used. The pores of polyacrylamide gels are appropriate for separating proteins and small nucleic acids. Agarose gels are appropriate for separating DNA, RNA and large proteins.
