gel e·lec·tro·pho·re·sis

electrophoresis through a gel, usually a cylindric tube or on a slab consisting of a gel of uniform composition.

gel electrophoresis

n.
Electrophoresis performed in a gel composed of agarose, polyacrylamide, or starch.

gel electrophoresis

The separation of whole or fragmented molecules, such as nucleic acids, through an electrically charged gel. The smaller the molecule, the faster its migration through the gel.

gel electrophoresis

ELECTROPHORESIS in a gel matrix, commonly agarose or polyacrylamide. This technique allows molecules to be separated on the basis of charge-to-size ratio, using the gel as a support and a sieving material. For example, sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDSPAGE) can be used to separate PROTEINS, and agarose or polyacrylamide gel electrophoresis (PAGE) to separate NUCLEIC ACIDS.
