Preservation Method of Trihydroxymethyl Aminomethane

 

When it comes to biological buffering agents, the first thing that comes to mind is trimethylaminomethyl, also known as tris. The reason may be that tris is a highly grounded biochemical reagent with a wide range of uses, which can be seen almost everywhere in daily life: it is an efficient skincare ingredient; It is a common pharmaceutical intermediate; It is an important component in new coatings; It is also an essential buffer component in virus preservation solution.

 

Tris is a zwitterion buffer, which is white powder with good water solubility and is vulnerable to temperature changes. Tris is a weakly alkaline substance with a pH value of around 10.5 in an aqueous solution. When using it, it is generally necessary to add an appropriate amount of hydrochloric acid to adjust to the desired pH value to obtain a buffer solution with that pH value. According to buffering theory, the effective buffering range of tris is between pH 7.0 and 9.2.

 

When storing Tris powder, it is first necessary to pay attention to moisture-proof measures to prevent clumping and affecting the effectiveness of use; Secondly, tris is prone to chemical reactions with carbon dioxide in the air, which affects its effectiveness. Therefore, in addition to being cool, dry, and well ventilated during storage, it is also important to pay special attention to sealed storage. After removing some tris, it is necessary to seal it as soon as possible. In addition, metal substances such as tris copper and aluminum have a certain corrosive effect, and should be carefully classified and separated during storage.

 

After Tris is configured as a solution, changes in temperature will directly lead to changes in its pH value. It is generally recommended to store at a temperature of 4 degrees Celsius. Of course, room temperature storage or low-temperature storage at minus 20 degrees Celsius can also be used, which depends on specific experimental requirements. In addition to paying attention to the influence of temperature, it is also necessary to always observe whether the tris solution has deteriorated, grown bacteria, or impurities. If these conditions exist, it is not advisable to continue using it.
