By the 1960s, increasingly sophisticated gel electrophoresis methods made it possible to separate biological molecules based on minute physical and chemical differences, helping to drive the rise of molecular biology.

FFE was developed in the 1960s by Kurt Hannig at the Max-Planck-Institute in Germany. Until the 1980s, it was a standardized technology for the separation of cells and organelles, and FFE was even tested in space to minimize the sedimentation under zero gravity.
1930s – first reports of the use of sucrose for gel electrophoresis; moving-boundary electrophoresis ; 1950 – introduction of "zone electrophoresis" (Tiselius); paper electrophoresis; 1955 – introduction of starch gels, mediocre separation
Electrochemistry. English chemist John Daniell (left) and physicist Michael Faraday (right), both credited as founders of electrochemistry. Electrochemistry is the branch of physical chemistry concerned with the relationship between electrical potential difference and identifiable chemical change. These reactions involve electrons moving via an ...
In the early 1960s, he developed new applications for gel electrophoresis. He applied the technique to identify different versions of the same protein, reflecting different alleles for the same genetic locus, in fruit flies.
Moving-boundary electrophoresis was developed by Arne Tiselius in 1930. [3] Tiselius was awarded the 1948 Nobel Prize in chemistry for his work on the separation of colloids through electrophoresis, the motion of charged particles through a stationary liquid under the influence of an electric field.
Agarose gel electrophoresis is a method of gel electrophoresis used in biochemistry, molecular biology, genetics, and clinical chemistry to separate a mixed population of macromolecules such as DNA or proteins in a matrix of agarose, one of the two main components of agar.
Arne Wilhelm Kaurin Tiselius (10 August 1902 – 29 October 1971) was a Swedish biochemist who won the Nobel Prize in Chemistry in 1948 "for his research on electrophoresis and adsorption analysis, especially for his discoveries concerning the complex nature of the serum proteins."
Gel electrophoresis of nucleic acids is an analytical technique to separate DNA or RNA fragments by size and reactivity. Nucleic acid molecules are placed on a gel, where an electric field induces the nucleic acids (which are negatively charged due to their sugar- phosphate backbone) to migrate toward the positively charged anode.
