Power Supply
First, the power supply for electrophoresis cameras is connected to the system camera, thus establishing an electric field between the two electrodes. Afterwards the DNA samples loaded into an agarose gel will move through the gel to the anode with the agarose gel matrix separating the DNA molecules by size.
Electrophoresis power supplies typically have a variable output voltage that allows the operator to set the output voltage for cameras of different sizes and modify the voltage for better results. The power source for electrophoresis is designed for continuous use in the separation of DNA, RNA and proteins. Therefore, failures in the power supply of the electrophoresis cameras can also cause failures in the results of the technique, which is why it is vital to ensure that the power supply is working properly.
Types of Lab Power Supply a Lab May Need
Basic Power Supply
The power source for electrophoresis systems converts the alternating current that comes from the electrical supply, into direct current, and distributes it to the devices that request it. That is why it acts as a transformer, rectifier and as a regulator at its output, to avoid voltage peaks that damage the system.
The power of the Electrophoresis Power Source is designed for use in separating DNA, RNA, and proteins. And you must bear in mind that failures in the power supply of the electrophoresis chambers, can in turn cause failures in the execution of the technique, so we must ensure that it works in the correct way and that its capacity is sufficient to cover the power requirements of all internal components of the electrophoresis system.
High-voltage Power Supply
Recalling a bit the principle of electrophoresis, we find that it is a technique that consists of the migration of molecules through a gel or matrix of a porous nature, where by the application of an electric field, they will be separated according to their size or molecular weight, this thanks to the action of a power source for electrophoresis chambers.
Electrophoresis chambers can be classified according to the way the support is arranged, horizontally or vertically. The horizontal ones are characterized by the fact that the buffer completely covers the gel, it has some wells in which the sample is deposited; those of the vertical type are used exclusively with polyacrylamide gel.
