The movement of small particles like DNA, RNA, or proteins through a gel by the application of electricity. The matrix nature of the gel (a semi-solid colloidal system consisting of a solid dispersed in a liquid) acts as a sieve to slow the progress of the molecules. Smaller molecules move more rapidly and thus further. The Gel electrophoresis separates molecules on size bais, but is also influenced by molecule shape and charge density.

Gel Documentations Systems are used for imaging ethidium bromide stained DNA gels. A Gel Doc System contains a quantitation analysis software to analyze the gel images made with the built-in CCD Camera. The camera is placed in a Darkroom on top of the Benchtop Gel Doc System, in the Bottom of the darkroom is a UV Transilluminator placed.
