A power source for electrophoresis is a device that manages the current in a constant and direct way to the electrophoresis system, as well as indicates and controls both the supply voltage and the current consumption. In other words, this equipment supplies the energy necessary for this system to function properly; and this delicate laboratory technique can be carried out.
Electrophoresis is a molecular biology technique based on the migration of molecules through a gel or matrix of porous nature, to which an electric field is applied, to separate these molecules according to their size or molecular weight, this thanks to the action of a power source for electrophoresis chambers, since this component is responsible for providing the electric field necessary to be able to displace or mobilize the molecules.
This principle is based on the techniques used for the migration of molecules, this process is performed in a kind of box which has a charge with a positive end on one side and a negative charge on the other side, when placed inside a charged molecule, it moves following a specific pattern, that is, if the molecules have negative charge they will migrate to the positive charge, but on the contrary if it is positively charged as it will move to the negative side.
When you analyze the proteins in a gel you take the whole protein to see how big it is, meeting the next principle that the shorter, the more they migrate into the gel, so that the small proteins will end up at the bottom of the gel, because they’ve gone further, and the larger ones will end up staying at the top. But in the case of DNA, we work with a very long molecule, so scientists opt to cut DNA with things like restriction enzymes, making DNA more manageable into smaller pieces, then depending on how big they are, they migrate more or less through the gel and end up higher or lower.
Electrophoresis in agarose or polyacrylamide gels is one of the methodologies most used in the laboratory in everything related to working with nucleic acids. The principle of electrophoresis consists in the migration of the molecules through a gel or another type of matrix of 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, key equipment for the proper execution of this technique.
