Micropreparation-type gel electrophoresis device and use method thereof

The invention relates to a micro gel electrophoresis device and a use method thereof. The micro gel electrophoresis device is characterized by comprising a preparation-type gel electrophoresis separation device and a preparation-type gel electrophoresis elution collection device, wherein the preparation-type gel electrophoresis separation device comprises two clamp plates, two gel preparation glass plates, a base and a refrigerating device; the two gel preparation glass plates are arranged in grooves formed in the inner side surfaces of the two clamp plates respectively; the depths of the two grooves are less than the thicknesses of the two gel preparation glass plates; the two clamp plates are placed with the inner side surfaces opposite, locked via screws and then arranged in the base in an inserting manner; the refrigerating device comprises two refrigerating pieces; the two refrigerating pieces are arranged on the outer sides of the two clamp plates respectively, and parallel to vertical planes of the two clamp plates; the preparation-type gel electrophoresis elution collection device comprises two clamp plates, an electrode cover and a collection groove; the two clamp plates are placed with the inner side surfaces opposite, and locked via screws; the electrode cover is arranged above the two clamp plates; and the collection groove is formed below the two clamp plates. The micro gel electrophoresis device can be widely used for proteomics analysis and medicine protein separation and purification.
