Electroelution

Equipment for bioanalytical continuous-elution gel electrophoresis: electrophoresis chamber, peristaltic pump, fraction collector, buffer recirculation pump and UV detector (in a refrigerator), power supply and recorder (on a table).[1]

Electroelution is a method used to extract a nucleic acid or a protein sample from an electrophoresis gel by applying a negative current in the plane of the smallest dimension of the gel, drawing the macromolecule to the surface for extraction and subsequent analysis.[2] For example, electroblotting and preparative native PAGE are based upon the same principle.[3][4]
