Electrophoresis is a basic method in the field of molecular biology for the analysis (separation, purification, preparation) of nucleic acids and proteins. The principle of electrophoresis consists in the migration of the molecules through a gel or another type of matrix of a porous nature, in which, by the action of an electric field, they will be separated according to their size or molecular weight, this is achieved thanks to the action of a power source for electrophoresis.
