Electrophoresis is an analytical method in which a controlled electric current is used to separate biomolecules according to their size to the electric charge ratio, using a gelatinous matrix as a base.
This technique has a variety of practical uses, such as forensic medicine for human identification, the human genome project, genetic and protein mutation research, and clinical diagnostic testing.
Electrophoresis is performed with equipment made up of a negative charge at one end and a positive charge at the other, called an electrophoresis system. When inserting charged molecules, in this environment, the negative ones will go to one extreme and the positive ones to the other corresponding.
