Electrophoresis is the movement of scattered particles comparative with a liquid affected by a spatially uniform electric field. Electrophoresis of decidedly charged particles (cations) is in some cases called cataphoresis, while electrophoresis of adversely charged particles (anions) is some of the time called anaphoresis.

The electrokinetic marvel of electrophoresis was watched without precedent for 1807 by Russian teachers Peter Ivanovich Strakhov and Ferdinand Frederic Reuss at Moscow State University, who saw that the utilization of a consistent electric field caused mud particles scattered in water to relocate. It is at last brought about by the nearness of a charged interface between the molecule surface and the encompassing liquid. It is the reason for diagnostic strategies utilized in science for isolating particles by size, charge, or restricting partiality.

Electrophoresis is utilized in research facilities to isolate macromolecules dependent on size. The procedure applies a negative charge so proteins move towards a positive charge. Electrophoresis is utilized broadly in DNA, RNA and protein investigation.
