Means of separating macromolecules that is based upon a combination of size-dependent interference with movement along with a substance's charge.

In gel electrophoresis it is smaller, more highly charged compounds that move faster.

Gel materials can range from agarose (for many DNA gels), potato starch (for proteins in their native state, that is, not denatured), and polyacrylamide (as employed in SDS-PAGE for denatured proteins).
