polyacrylamide gel electrophoresis: a gel formed by cross-linking of acrylamide that is used for the separation of proteins or nucleic acids. These substances are separated on the basis of both size and charge.
polyacrylamide are physically stronger than those prepared from agarose . Polyacrylamide gel electrophoresis (PAGE) is based on gels formed by long chains of covalently cross-linked acrylamide monomers . Polymerization employs purified
