Hubei Xindesheng was established in 2017. It is a new technology-based enterprise established on the basis of Wuhan Desheng Biochemical Technology Co., Ltd. (2005). After years of innovation and development, the company has now become a leader in "blood collection tube additives", "chemiluminescence reagents", "biological buffers", "color reagents", etc., integrating R&D, production, sales and service. high-tech enterprises. Tris, as the company's main advantage product in biological buffers, has always had its own advantages: 1. TRIS is used as a neutralizer in cosmetics, which is actually a PH regulator. 2. Tris is used as a solvent for nucleic acids and proteins and as a biological buffer. 3. It can be used to prevent and treat metabolic acidosis and respiratory acidosis; 4. Tris is used to prepare surfactants, vulcanization accelerators and intermediates for some drugs. 5. Tris mainly acts as a pH regulator, cross-linking accelerator, polyester coating raw material and phase change core material in the coating preparation process; 6. Products related to Tris can be prepared through the molecular structure of Tris. Such as Bis-Tris, Tricine, TES, TAPS, etc. From the above points, we can see that Tris itself has a wide range of applications, but it is not a simple matter to make high-quality Tris. In the past ten years, Desheng has been learning and improving its technology. The Tris produced is white crystalline powder; it has good solubility in water systems and minimal solubility in organic solvents; it is in dry or solution state. It has excellent stability and can resist enzymatic or non-enzymatic degradation; it has a very small absorption value for visible light and ultraviolet light. Therefore, when we store tris, we only need to store it in a cool, dry and moisture-proof warehouse at room temperature. Desheng is a professional TRIS manufacturer, committed to providing customers with high-quality products and services that can meet the special requirements of R&D customers for product types, packaging, purity and other aspects.
The structure and function of the protein need to be maintained in a suitable pH environment. Therefore, the choice of pH buffer is very important during the preparation and purification of the protein. Only a suitable buffer can ensure the activity and structural stability of the protein. Effect of buffer in protein purification process There are many kinds of buffers for protein purification. While maintaining the pH of the system, it is necessary to ensure that the protein cannot be inactivated during the purification process, or to minimize the amount of protein inactivation, which must be maintained in every step of protein purification. Solubility and activity of protein. Protein purification buffer requirements The buffer in the protein purification process should not only prevent protein degradation, but also prevent protein aggregation, which has a significant impact on the experimental results. The following factors should be considered when selecting and reagent buffers: pH, buffer system, salt ions, reducing agents and stabilizers. Each of these factors should be optimized according to the purified target protein, and the activity of the target protein should be used as an evaluation criterion for optimization. Understand protein stability conditions There are many types of proteins, and different proteins adapt to different pH values. The buffer should be selected according to its optimal pH value. In many cases, the pH is 7.4, which is a mimic biological condition, and most proteins are stable at this pH. However, there are some exceptions, which require pH adjustment to keep the protein soluble and not degraded. Commonly used buffers for protein purification Commonly used buffers in the protein purification process include Tris, Tricine, Bis-Tris, MOPS, etc. Among them, Tris is commonly used. Its buffer range is close to physiological pH and has a low ionic strength. It is a good solvent for proteins. Can ensure the stability of the protein. It should be noted that when preparing the buffer, try to avoid the isoelectric point pl of the target protein. Because the protein has no electrostatic charge on its surface in the pH solution of its isoelectric point, the repulsive force between the hundred molecules is reduced, it is easy to aggregate, and the solubility is reduced. Now the adaptation pH value, isoelectric point, and buffer range of the buffer to be purified can be found, and you can directly match it according to the corresponding requirements. Desheng is a manufacturer of in vitro diagnostic reagents, which can provide large-package pH buffers such as Tris, MOPS, Bicine, etc.

Because there is glycine in the buffer, it is difficult to distinguish whether glycine is brought in by buffer or the protein itself during sequencing. Now, 10mm / 1caps10% methanol is used as membrane transfer buffer for sequencing, and the methanol concentration range in caps electroimprinting buffer is 0-20%. Generally, the methanol concentration is high The buffer has a good effect on the transfer of low molecular weight protein, while the buffer with low methanol concentration or even without methanol is conducive to the transfer of high molecular weight protein. |Product advantage|The purity is |99%, with good water solubility and stable process, which can ensure that the product appearance is pure white crystal powder.

The Chinese name of Tris is tris(hydroxymethyl)aminomethane, tromethamine, tromethamine, 2-amino-2-(hydroxymethyl)-1,3-propanediol. It is a white crystal or powder. Soluble in ethanol and water, slightly soluble in ethyl acetate and benzene, insoluble in ether and carbon tetrachloride, corrosive to copper and aluminum, and irritating chemicals. Tris has a high buffer capacity, high solubility in water, and is inert to many enzymatic reactions, making Tris a very satisfactory buffer for many biochemical purposes. It is generally used to stabilize the pH of the reaction system, and has a strong buffering capacity between pH 7.5-9.0. Advantages of Tris buffer: 1. Because Tris base is more alkaline, you can only use this buffer system to configure a buffer with a wide range of pH ranging from acidic to alkaline; 2. It has little interference to biochemical processes, and does not precipitate with calcium, magnesium ions and heavy metal ions. Disadvantages of Tris buffer: 1. The pH of the buffer is greatly affected by the concentration of the solution, the buffer is diluted ten times, and the pH change is greater than 0.1; 2. The temperature effect is large, and the temperature change has a great influence on the pH of the buffer. The pH of the buffer at 4�?�°C is 8.4, and the pH at 37�?�°C is 7.4. It must be prepared at the temperature of use, and prepared at room temperature Tris-HCL buffer cannot be used for 0-4; 3. It is easy to absorb CO2 in the air, so the prepared buffer should be tightly sealed; 4. This buffer has a certain interference effect on some PH electrodes, so use electrodes that are compatible with Tris solution. Application of Tris buffer: It forms a buffer system with glycine in the electrophoresis buffer to stabilize the pH; uses the Tris-HCL buffer system in the gel to stabilize the pH; it is widely used as a solvent for nucleic acids and proteins; the low ionic strength of the Tris buffer can also be used The formation of intermediate fibers of nematodes; add EDTA to Tris hydrochloric acid buffer to make "TE buffer", which can be used for DNA stabilization and storage; change the pH-adjusting acid solution to acetic acid to obtain "TAE buffer", change "TBE buffer" can be obtained as boric acid. These two solutions are used in nucleic acid electrophoresis experiments.
