Gel Electrophoresis

A technique used for the separation of DNA, RNA or protein molecules by using an electric current applied to a gel matrix. The gel is the medium used to contain, then separate the target molecules. Electrophoresis refers to the use of electricity to move the molecules through the gel matrix. Placing the molecules in wells in the gel and applying an electric current moves the molecules through the matrix at different rates based on their size, charge and/or shape.
