What is Agarose Gel Electrophoresis?
Agarose gel electrophoresis is a method used in biochemistry and molecular biology to separate DNA, or RNA molecules by size however proteins can also be separated on agarose gels. Separation of the molecules is achieved by moving negatively charged nucleic acid molecules through an agarose matrix in an electric field (see electrophoresis). Shorter molecules move faster and migrate further than longer ones.
