Gel eletrophoresis refers to the technique in which molecules are forced across a gel by an electrical current from activated electrodes at both ends of the gel. Can be used to separate DNA, proteins, and other gene products.

Under the influence of an electrical field charged molecules and particles migrate in the direction of the electrode bearing the opposite charge. During this process, the substances are usually in aqueous solution. Because of their varying charges and masses, different molecules and particles of a mixture will migrate at different velocities and will thus be separated into single fractions.
