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.
A range of sizes is available, ranging from 6mm to 200mm diameter. Parts with fastenings on both sides can be used in shear and compression or a combination of both. Parts with fastenings on one side can be used as bump stops to absorb shock loads or as mounting feet. Some buffers sizes are subject to minimum order quantities.

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.

Buffer solution is a type of buffer system dedicated to life science research. In biochemical experiments, buffer solution plays an indispensable role. It can resist the influence of a small amount of strong acid and alkali from the outside, and maintain the system closest to the physiological environment. pH value. Both HEPES and PIPES buffers are commonly used buffers in biological experiments. The pH buffer range of HEPES is 6.8-8.2. It is a zwitterionic biological buffer. It is soluble in water and does not form stable complexes with metal ions. In most cases, it will not interfere with biochemical processes and can be widely used in a variety of Biochemical reactions and used as buffer reagents in certain cell culture media. HEPES is often used in the cell culture medium of various types of organisms; in protein research, PIPES is often used as the component and eluent of the binding buffer in cation exchange chromatography; in DNA research, PIPES is used as calcium phosphate and DNA The buffer for the precipitation formation system, AFM and the buffer for electroporation experiments. In addition, HEPES interferes with the reaction between DNA and restriction enzymes, and is not suitable for Lowry's method to determine protein content. HEPES buffer is often used in the research of organelles and highly variable, pH-sensitive proteins and enzymes, as well as in biochemical diagnostic kits, DNA/RNA extraction kits and PCR diagnostic kits. It is a hydrogen ion buffer that can control a constant pH range for a long time. The final concentration is 10-50mmol/L, and the buffering capacity can be achieved when the culture medium contains 20mmol/L HEPES. The pH buffer range of PIPES is 6.1-7.5, insoluble in water, soluble in NaOH aqueous solution. PIPES is different from buffers containing two (2-hydroxyethyl) amino groups (such as Bis-tris, Bicine), and can not form stable complexes with most metal ions. It is suitable for buffers in solution systems containing metal ions. According to existing research results, PIPES can be used to purify tubulin using phosphocellulose chromatography, to purify recombinant GTP-binding proteins ARF1 and ARF2 by gel filtration, and to use as a buffer to crystallize transketolase from E. coli. In addition, because PIPES can form free radicals, it is not suitable for redox systems. In cation exchange chromatography, a low concentration of PIPES buffer should be used, because PIPES has a relatively large ionic strength and its pKa value is concentration-dependent. We must learn to distinguish between the similarities and differences in these reagents, so as to better promote the development and production of our different products. Desheng unanimously adheres to this kind of subtle difference, so that it can continue to develop and produce better products.
With every passing day, human beings are vouching for sustainable ways to get a life free of harmful chemicals and other toxic products. Hence, the coco peat or coco coir has gained massive popularity as a perfect growing medium in horticulture. But there are several processes included in the coco coir treatment and without proper processing of the coco coir; it will create an imbalance in the proposition of calcium and magnesium in the soil. Among all the treatment processes, the buffering of coco coir is one of the main treatments done on the coco coir. Buffering is a time-consuming process and it starts with proper flushing and rinsing of the coir with clean water. This extensive washing with clean water removes the water soluble particles. Once the process of washing with water is completed then the coir is rinsed well with a solution of calcium nitrate for a long time. This removes the residual Sodium-Potassium complex in the coir along with all the elements that bond easily with the coir cation exchange. The process is repeated for three to four times to get fully cleaned and buffered coir that helps your plants to grow in a healthy way. There are several uses of buffered coir and it is not possible to list them all. Hence, here are some best uses of buffered coir: Used mainly for transplantation of tissue cultured plants from the beakers to a perfect medium prepared over a tray Considered as one of the best-growing mediums in the Indian as well as International horticultural market The buffered coir is also used for propagating the starting of seeds and plugs
