How To Make 10x Tbe

How To Make 10x Tbe – In molecular biology, agarose gel electrophoresis is a common technique used in many applications, such as amplification, screening your PCR products, or checking the absence of your DNA. One of the conditions for gel electrophoresis is a liquid buffer, such as TBE buffer or TAE buffer.

But what is the difference between TBE and TAE? And when is TBE or TAE the best choice?

How To Make 10x Tbe

The main difference between TBE and TAE, from a chemical point of view, has to do with composition. TBE consists of Tris, boric acid and EDTA. TAE contains Tris base, glacial acetic acid and EDTA. TBE is a good choice when you need high resolution for small DNA fragments. TAE is a good choice when working with larger DNA fragments or for cloning.

Agarose gel electrophoresis enables the separation of nucleic acids, such as DNA and RNA, according to their molecular weight using electricity and using the reduced form of nucleic acids using a sugar-phosphate backbone.

The negative charge allows the nucleic acid to move through the agarose matrix in the electric field to the positive pole.

Therefore, nucleic acids will move towards the positive pole faster or faster, depending on the weight and charge of the molecule. Smaller molecules flow faster than larger molecules during gel electrophoresis.

After gel electrophoresis, nucleic acid fragments are separated according to size. Then the results are analyzed, interpreted and analyzed.

In gel electrophoresis, since the movement of DNA molecules is controlled by the concentration of the agarose gel, it is also highly dependent on the flow rate; its structure and ionic strength.

The function of TBE and TAE buffers is to allow the nucleic acid to move through the agarose matrix. Therefore, the agarose gel should be thoroughly immersed in the buffer.

In addition, TBE or TAE maintains pH and ion concentration during electrophoresis. The pH remains in the appropriate range because the buffer contains weak acids.

It is important to maintain the pH of the solution because changes in pH affect the charge of nucleic acids. Therefore, if the pH is within the desired range, the net charge will remain constant and the nucleic acid will function optimally.

Nucleases can inadvertently contaminate your nucleic acid samples. EDTA prevents these enzymes from breaking down your sample even if contaminants are present.

The main difference in the composition of these defenses is that TBE contains boric acid and TAE contains glacial acetic acid.

These weak acids ensure the correct concentration of ions and maintain the correct pH as the nucleic acid moves through the agarose matrix.

TBE stands for Tris-borate-EDTA. Contains Tris base, boric acid and EDTA. This buffer is used for agarose gel electrophoresis. In addition, it is often used to analyze DNA products from PCR using agarose gel electrophoresis or polyacrylamide gel electrophoresis.

TAE is Tris-acetate-EDTA. This buffer contains Tris base, glacial acetic acid and EDTA. It is often used as a liquid buffer in gel electrophoresis to separate nucleic acids.
