Electrophoresis

Electrophoresis is a technique used by scientists in the laboratory used to separate DNA, RNA, or molecules or proteins based on their size and electrical charge. An electrical current is used to move the molecules and separate them through a gel. The pores of the gel act like a strainer, allowing smaller molecules to move faster than larger ones. The conditions used during electrophoresis can be adjusted to separate molecules in the desired size range.

This way in which this technique is used has a variety of practical uses, such as forensic medicine for the identification of people, the human genome project, protein and genetic mutation research, and clinical diagnostic tests.

Electrophoresis is carried out with equipment composed of a negative charge at one end and a positive charge at the other. When inserting charged molecules, in this environment, the negative ones will go to one extreme and the positive ones to the other corresponding.

Electrophoresis and Gel Documentation Systems

It should be noted that gel electrophoresis is one of the main tools in molecular, cellular and biochemical biology laboratories. In fact, it remains one of the main endorsements and trials requested when publishing important results. For this reason, researchers require high-resolution systems and multiple image recognition systems to process the gels. From this point of view, the processing of the gels requires the highest sensitivity to ensure the quality of the results.

Vertical Gel Electrophoresis

The vertical gel electrophoresis technique works according to the primary theory of gel electrophoresis, but is considered to be more complex than the horizontal gel electrophoresis method. This technique uses a discontinuous buffer. A cathode is located in the upper chamber, and the anode is located in the lower chamber. The electrodes present in each compartment provide the required electric field. A thin layer of gel is poured between the two mounted glass plates. Therefore, the upper part of the gel is immersed in the upper chamber, and the lower part of the gel is immersed in the lower chamber. Once the current is applied, a small portion of the buffer moves to the lower chamber from the upper chamber through the gel.

Horizontal Gel Electrophoresis

Horizontal gel electrophoresis uses the basic theory for the separation of DNA, RNA or protein molecules according to their respective molecular size and charge. In this technique, the gel is present in a horizontal orientation and is immersed in a buffer that is continuous. The agarose gel is used to separate the gel box into two compartments. One end of the gel box contains an anode, while the other end contains a cathode. When a current is applied, the buffer used in this technique allows the creation of a charge gradient. When the load is applied, the gel tends to heat up.

Electrophoresis is a common technique in the clinical laboratory. It allows the separation of chemical species (nucleic acids or proteins) along an electric field based on their size and their electric charge.

Agarose gel electrophoresis

Agarose gel electrophoresis is one of the most used to analyze
and characterize nucleic acids from different sources.

Polyacrylamide Gel Electrophoresis

It allows the separation of a mixture of proteins according to their molecular weight and is the entry technique for performing the Western-Blot

Capillary electrophoresis

Capillary electrophoresis is an analytical technique used in different areas of research, especially aesthetics, pharmacists and doctors.

Our Best Selling Electrophoresis System

The Vertical Gel Electrophoresis Cell YR03429

Vertical gel electrophoresis is a more complex setup compared to horizontal gel system. Researchers typically use this system to separate proteins rather than nucleic acids. However, before separating the proteins, you must break the quaternary structure of the proteins at the linear strand. Both DNA and protein molecules are analyzed and this is an important part of the routine procedure of nucleic acid and protein analysis.

What is electrophoresis?

Electrophoresis is an analytical method in which a controlled electric current is used in order to separate biomolecules according to their size-to-electric charge ratio.

Source for electrophoresis

Electrophoresis is a basic method in the field of molecular biology for the analysis (separation, purification, preparation) of nucleic acids and proteins

Electrophoresis and Gel System

Gel electrophoresis is a widely used technique in life science laboratories to separate macromolecules

Horizontal and vertical electrophoresis: Differences

Gel electrophoresis is a laboratory technique used in genetics to separate mixtures containing DNA, RNA and other proteins according to their respective molecular size and charge. The DNA, RNA, or proteins that must be separated in this method are run through a gel that contains small pores. The molecules are driven through the gel by an electric field.
