The history of electrophoresis for molecular separation and chemical analysis began with the work of Arne Tiselius in 1931, while new separation processes and chemical speciation analysis techniques based on electrophoresis continue to be developed in the 21st century. [1]

Gel electrophoresis is an electrophoresis method for separation and analysis of biomacromolecules (DNA, RNA, proteins, etc.) and their fragments, based on their size and charge through a supportive medium.
Electrophoresis became widely developed in the 1940s and 1950s when the technique was applied to molecules ranging from the largest proteins to amino acids and even inorganic ions. During the 1960s and 1970s quantum electrochemistry was developed by Revaz Dogonadze and his pupils.
Two-dimensional gel electrophoresis, abbreviated as 2-DE or 2-D electrophoresis, is a form of gel electrophoresis commonly used to analyze proteins. Mixtures of proteins are separated by two properties in two dimensions on 2D gels. 2-DE was first independently introduced by O'Farrell [ 1 ] and Klose [ 2 ] in 1975.
The moving-boundary electrophoresis apparatus includes a U-shaped cell filled with buffer solution and electrodes immersed at its ends. The sample applied could be any mixture of charged components such as a protein mixture. On applying voltage, the compounds will migrate to the anode or cathode depending on their charges.
Electrophoresis is a method of moving charged particles through a medium by using an electric field induced by electrodes. It is also used to separate molecules with different physical characteristics using electrical charges.
Pulsed-field gel electrophoresis (PFGE) is a technique used for the separation of large DNA molecules by applying an electric field that periodically changes direction to a gel matrix. [ 1 ] [ 2 ] Unlike standard agarose gel electrophoresis , which can separate DNA fragments of up to 50 kb, PFGE resolves fragments up to 10 Mb. [ 1 ]
