Electrophoresis process is essential for the successful analysis of biological samples

Electrophoresis 

The electrophoresis is a process that involves the movement of dispersed particles through a liquid under the influence of an electric field. The process can be useful in many applications, including the study of proteins, DNA, RNA, and mRNA.

First, a gel needs to be prepared. The gel has two electrodes: a positive electrode and a negative one. The gel is filled with a buffer solution containing salt, which allows it to conduct electricity. The gel should be just barely covered with buffer solution. The gel's wells should be facing towards the positive electrode, and the other end should be facing the negative electrode. The process cycle is completed when all fragments of DNA have migrated across the gel.

The Global Electrophoresis Market is estimated to be valued at US$ 2,786.3 Mn in 2021 and is expected to exhibit a CAGR of 5.6 % over the forecast period (2021-2028). 

The gel contains a pore-like material, called an agarose gel. The pore-like material allows particles to move more or less freely through the gel. The pore size and concentration of the gel matrix determine the size of the particles and how quickly they move through the gel. The pH level of the environment is also controlled by adding liquid buffer.

A gel that contains protein or nucleic acid molecules will separate them from other molecules. The charged molecules will migrate more quickly on the side with more current. The opposite happens if the electrodes are not aligned correctly. If the electrodes are not aligned correctly, the proteins will migrate into the buffer. If the electrophoresis is too long, the proteins will migrate into the buffer. This is called a "smile artifact," where the proteins migrate toward the middle of the gel, and those at the edges will migrate farther.

Another common use of electrophoresis is in the clinical laboratory. It is used to separate proteins and nucleic acids from homogeneous solution. In addition to protein separations, it can be used for the study of protein antigens. The technique can also be used for the analysis of large DNA molecules.
