The Role of Trimethylolaminomethane in Virus Transport Media│CAS77-86-1
Latest company news about The Role of Trimethylolaminomethane in Virus Transport Media│CAS77-86-1

Trimethylolaminomethane, CAS77-86-1, commonly known as Tris, also known as tromethamine, is a very commonly used reagent, which is widely used in industrial synthesis, biochemical testing, and biopharmaceutical fields; The virus transport media sample tube belongs to an important raw material of its configuration solution.

 

Trismethylaminomethane Tris molecular structure contains one amino group and three alcoholic hydroxyl groups. The amino group and three methylol groups form a methane-like tetrahedral structure around the central carbon atom. Due to the presence of amino groups, Tris is weakly basic in aqueous solution. The amino group can be used as a coordination group to form Tris salts with many acids. Commonly, Tris-HCl, TEA, TEB, Tris glycine, and Tris phosphoric acid are also used. The raw materials used in the virus transport media are Tris and EDTA. The actual TE buffer is Tris plus EDTA.

Adding Tris to the virus transport meida can first maintain the pH value of the sampled sample and act as a biological buffer. The virus and its nucleic acid are relatively sensitive to the environmental pH. The nucleic acid (DNA, RNA) is easily hydrolyzed in acidic solution. It is more stable in neutral or weak alkaline solution. The Tris hydroxymethylaminomethane, PH buffer range: 7.0-9.0, can maintain the stability of the nucleic acid released after the sample to be cleaved to avoid degradation of the nucleic acid, increase the concentration and purity of the nucleic acid, and help to improve the quality of the nucleic acid To ensure the accuracy of subsequent nucleic acid detection and analysis operations.

 

Tris buffer is a weak alkaline solution. In such a solution, DNA will be deprotonated to improve its solubility. Therefore, Tris buffer is generally used in the dissolution of nucleic acids and nucleic acid extraction. It should be noted that because it is alkaline when disposing the solution, it will absorb carbon dioxide gas that can generate carbon dioxide in part of the air, so the cap of the bottle containing the Tris solution needs to be tightly capped. In addition, the Tris solution is sensitive to temperature. For every increase of 1 degree, the pH value drops by 0.03, and it needs to be maintained at room temperature during configuration.

 

Tris buffer is more and more widely used, and even has a tendency to exceed phosphate buffer. Because it does not react with calcium, magnesium and heavy metal ions, its performance is superior to phosphate buffer in many aspects. Desheng's products related to Tris include Tris reagent, Tris hydrochloric acid, TEA/TEB electrophoresis electrophoresis gel, etc., which are superior in quality and low in price.
