What are the main uses of N-Tris (Hydroxymethyl) Methyl-2-Amino-Ethanesulphonic Acid
N-tris (hydroxymethyl) methyl-2-aminoethanesulfonic acid, commonly known as TES, is a commonly used zwitterion buffer in biochemical research. Its main uses are roughly as follows.
First, in biochemistry and molecular biology experiments, it can create a stable pH environment. Many biochemical reactions are extremely sensitive to pH value, and slight changes may affect the reaction rate and results. TES buffers can effectively maintain the pH stability of the system and ensure the smooth development of enzymatic reactions, protein electrophoresis, nucleic acid hybridization and other experiments. For example, in the process of protein separation and purification, the use of TES buffers to maintain a suitable pH can avoid protein denaturation due to pH discomfort and ensure its structural and functional integrity.
Second, it plays a significant role in the field of cell culture. Cell growth requires strict environmental pH, and TES buffers can help maintain the pH stability of cell culture medium and create a good growth microenvironment for cells. When cells are cultured in vitro, metabolic activities will cause the pH of the culture medium to change, and the TES buffer system can be regulated in time to keep cells in a suitable pH range, promoting normal cell growth, proliferation and differentiation.
Third, it is also indispensable in drug development and preparation. The stability of drug active ingredients is often related to the pH of the environment. TES buffers can be used to adjust the pH of drug preparations, improve drug stability and solubility, and ensure drug efficacy. For example, in some oral preparations, by adding TES buffers, drugs can be prevented from decomposing or deactivating in different pH environments in the gastrointestinal tract, ensuring effective drug absorption.
Fourth, in the preparation of clinical diagnostic reagents, TES buffers help to improve the accuracy and reliability of diagnostic reagents by virtue of their pH stability properties. Many diagnostic tests rely on specific chemical reactions, and stabilizing the pH environment is the key to ensuring the specificity and sensitivity of the reaction. TES buffers can provide strong support for this.
What are the physicochemical properties of N-Tris (Hydroxymethyl) Methyl-2-Amino-Ethanesulphonic Acid
N-tris (hydroxymethyl) methyl-2-aminoethanesulfonic acid, often referred to as TES, is a very commonly used zwitterionic buffer in biochemical research. Its physicochemical properties are quite unique, as detailed below:
Looking at its properties, it is usually in the state of white crystalline powder, which is easy to store and use, and is convenient for laboratory operations. Its solubility is very good, and it is easily soluble in water. This property allows it to be rapidly and uniformly dispersed in aqueous systems, and can play a buffering role efficiently in many reaction media in biochemical experiments. In organic solvents, its solubility is relatively limited, and this property also limits its application scenarios.
When it comes to buffering properties, the buffering range of TES is roughly between pH 7.5 and 8.5. In this range, when a small amount of acid or base is added to the solution, it can effectively resist large fluctuations in pH value, ensuring that the pH value of the solution remains relatively stable. This property is crucial in many biochemical reactions that are extremely sensitive to pH changes. For example, in protein and enzyme related experiments, a suitable and stable pH environment is a key factor to ensure the stability of protein and enzyme activity and structure.
The melting point of TES is quite high, roughly between 150 ° C and 155 ° C. The higher melting point indicates that the intermolecular force is strong and the structure is relatively stable, which makes it able to maintain its own chemical stability under normal experimental conditions, and is not easy to decompose or denature due to small changes in temperature.
In addition, TES has good chemical stability, and it is not easy to react with common chemical reagents under normal storage and use conditions. However, under extreme conditions, such as strong acids, strong bases or high temperature environments, its chemical structure may be damaged, resulting in loss of buffering properties. Overall, N-tris (hydroxymethyl) methyl-2-aminoethanesulfonic acid has been widely used in many fields such as biochemistry and molecular biology due to its unique physicochemical properties.
What are the precautions for N-Tris (Hydroxymethyl) Methyl-2-Amino-Ethanesulphonic Acid during use?
N-tris (hydroxymethyl) methyl-2-aminoethanesulfonic acid, or TES, has many things to pay attention to in experimental use.
The first thing to pay attention to is its solubility. TES is easily soluble in water, but when it dissolves, it is advisable to use an appropriate amount of solvent and stir slowly to promote its instant dissolution and uniformity. If there is too little solvent or insufficient stirring, it is easy to cause the local concentration to be too high, which affects subsequent use.
Furthermore, pH regulation. TES is often used as a buffer, and the buffer range is about pH 7.5-8.5. When using, it is necessary to accurately measure and adjust the pH value of the system, and use pH meters and other tools to adjust the pH to an appropriate value according to the experimental needs. If the pH deviation, it is very likely to change the reaction environment and affect the experimental results.
Stability cannot be ignored. Although TES is relatively stable, it should avoid high temperature, strong acid and alkali environment to ensure its structure and property stability. When storing, it should be placed in a dry and cool place to prevent moisture and deterioration.
In addition, in biochemical experiments, when TES interacts with biological macromolecules such as proteins and enzymes, it may affect their activity and structure. Therefore, it must be fully considered before use, and pre-experimental evaluation can determine whether it interferes with the system.
At the end, when measuring TES, it must be accurate. Whether it is to configure the solution or participate in the reaction, the accuracy of the dosage has a great impact on the experimental results. Accurate measuring tools, such as pipettes and balances, should be used to achieve the purpose of accurate measurement. In this way, the experiment can be smooth and the results are reliable.
How to store N-Tris (Hydroxymethyl) Methyl-2-Amino-Ethanesulphonic Acid
N - Tris (Hydroxymethyl) Methyl - 2 - Amino - Ethanesulphonic Acid, Chinese name: N - Tris (Methyl) Methyl - 2 - Aminoethanesulfonic Acid, often used for TES. The existence of this chemical substance should be properly determined according to its characteristics.
TES properties are determined, but it is also necessary to install the appropriate parts to ensure their durability and activity. First, it is suitable for dry weather. If the environment is damp, it is easy to cause its moisture absorption, shadow products, or induce chemical properties to change. Therefore, it can be placed in the dry air, or the dry weather.
Second, the degree is also low. Generally speaking, it can be stored for a short time under normal conditions. However, if you want to store it for a long time, it should be placed in a low-temperature environment, such as refrigerated parts at 2-8 ° C. In this way, it can reduce the possible reaction rate and extend the shelf life.
Third, it is necessary to avoid light. Illumination or photochemical reaction, resulting in decomposition or sexual degradation. Therefore, it is appropriate to use opaque containers for storage, or store in the dark.
In addition, storage requires the separation of oxidized materials, raw materials and other substances that may react. Because of its specific properties, or because of the reaction of some substances, it can be destroyed.
Therefore, in order to properly store TES, it is necessary to pay attention to the separation of dryness, brightness, light and other materials in order to ensure its efficacy during the use of energy.
