#chemical <br>[a]https%3A%2F%2Fwww.hbdsbio.com%2Fproducts%2Ftoos-cas-no-82692-93-1.html[/a] <br>TOOS, full name N-ethyl-N-(2-hydroxy-3-sulfopropyl)-3-methylaniline sodium salt, a widely used chromogenic reagents, among the new Trinder&#039;s reagents, are most commonly used. TOOS is used in many clinical biochemical testing projects. <br>The TOOS chemical produced by Desheng is a white crystalline powder with CAS number 82692 93 1. In the field of in vitro diagnosis, it is mainly used for the detection of blood glucose metabolism series items, such as the preparation of glucose detection kits, glycated albumin detection kits, serum uric acid detection kits, etc. <br> <br>TOOS Product Advantages <br>In terms of the fading of the color product, the absorbance of the color reaction product formed by TOOS does not change much with time, that is, the color reaction product is stable and not easy to fade. <br>TOOS has good performance in absorption wavelength, color reaction intensity and fading, so TOOS is the most commonly used. <br>TOOS has a high molar absorbance, and can be used for the determination of very small amounts of the test items in serum. If the test items are in the 550nm~600nm range, and their content is extremely small, then MAOS and MADB need to be used. <br>The chromogen substrate TOOS produced by Desheng has the characteristics of high purity, good water solubility and small batch-to-batch variation; <br>The TOOS chemical produced by Desheng has the characteristics of less interfering impurity ions. It is very convenient to use when it is used. <br>Desheng TOOS products are pure white crystalline powder with uniform shape and good performance in color reaction intensity and fading; <br>Desheng has a professional foreign trade team, rich export experience, and can deal with various problems in transportation in a timely manner. <br> <br>Precautions for Use of TOOS <br>As a chromogen substrate product with reducing properties TOOS, although it is configured in the form of a solution during use, there will still be slow oxidation in the air, so in general, it is recommended to prepare and use now, and it is necessary to add a certain amount of excessive Catalyzed by oxidase, the chromogen substrates produced by Desheng are basically pure white crystalline powders, which will not be affected in a sealed environment, but will be slowly oxidized and discolored when exposed to air for a long time. <br> <br>What Testing Items Can TOOS Be Used For? <br>The chromogen substrate TOOS can be used in a variety of diagnostic reagents, such as blood sugar testing, routine liver function tests, blood lipid testing items such as triglycerides, and cholesterol testing items, and for different biochemical tests, the concentration used will be different. The concentration of TOOS chemical is basically around 1~5mmol/L under the state. TOOS raw material not only has the characteristics of high sensitivity and stability, but also has good performance in color reaction intensity and fading, which is of great value in clinical diagnosis. <br> <br>Preservation of Chromogen Substrate TOOS <br>The premise that TOOS can produce a color reaction is that it cannot be oxidized in advance during storage, otherwise it may cause a low detection result. Taking Desheng&#039;s TOOS reagent as an example, the finished products are all in the form of solid powder, which is stored in a seal at low temperature, so that TOOS powder will not be slowly oxidized by air due to long-term storage, nor will it deteriorate due to excessive temperature or exposure to light. . Also prevent storage with oxides and acids.

Since Gadopentetate Dimeglumine Injection was launched in 1992 by Beilu Pharma in China, it was highly recommended and accepted by the radiologist, and quickly occupied the market with its excellent quality and reasonable price.

#Buffer <br>[a]https%3A%2F%2Fwww.hbdsbio.com%2Fproducts%2Ftes-buffer-cas-no-7365-44-8.html[/a] <br>The name of TES is n-trimethylol-methyl-2 amino-ethanesulfonic acid. TES powder can not only be prepared into biological buffer, but also is a very important chemical raw material. It is widely used in biochemical research to regulate the pH of biochemical reactions. It is generally used as a dissolving agent or solution pH maintainer. <br>High quality TES(CAS No. 7365 44 8) is a white crystalline powder. It is quite similar to Tris-HCl powder. When the pH value of biochemical detection solution is 6.8-8.2, the buffering capacity of TES buffer can play the greatest role. TES buffer is an electrically neutral compound. At the same concentration, the force between TEs ions is greater than that between Tris ions. When detecting metal ions, TES buffer will not react with metal ions to produce other metal compounds. Therefore, when TES is used as the buffer solution of cell culture medium, it can provide positive divalent metal ions for the culture medium. <br> <br>TES Buffer (CAS No. 7365-44-8) Detailed Introduction <br>The solubility of TES in water is very high. When 5g tes is added to 100ml water, it can be completely dissolved and reach the saturated state. After dissolution, it is transparent. The solubility of TES will not change greatly with the change of temperature. As a biochemical buffer, TES buffer does not participate in chemical reactions, so it will not affect the research results. Desheng is a professional source manufacturer of TES. Our company can ensure that the TES crystal powder produced is pure white with a purity of 99%. With mature production technology and perfect equipment, we can ensure that the daily output of TEs can reach 2 tons per day, and fully meet the production delivery date under the condition of ensuring the quality. <br> <br>TES Buffer (CAS No. 7365-44-8) Advantages <br>TES is a non-toxic buffer; <br>High solubility in solution, so as not to waste reagent; <br>In the pH range of 6.5-8.2, it has good stability and can keep the pH value of the solution in a stable state for a long time; <br>The chemical property is not active and does not interfere with the test results due to chemical reaction with enzymes and metal ions; <br>Little absorption of visible light or ultraviolet light. <br>Superb purification technology can ensure that the purity is higher than 99% and almost free of other impurities; <br>The experienced production team and quality assurance personnel shall strictly control the quality of TES; <br> <br>TES Buffer (CAS No. 7365-44-8) Applications <br>In the process of oxidation of succinic acid (succinic acid) to carbon dioxide, TES is more suitable than other buffers to maintain the pH of the solution; <br>TES is needed as a buffer medium to ensure the accuracy of the test in the refrigeration and transportation of sperm yolk storage solution; <br>In protein purification, separation and determination, TES buffer is used to maintain the pH value required by the test; <br>Like most amine buffers, TEs can form complexes with DNA, so it can be used as cell washing buffer; <br>TES, 4-hydroxyethyl piperazine ethanesulfonic acid and trimethylolaminomethane can inhibit the activity of the enzyme, but the influence of TEs on the enzyme is between the other two; <br>TES can affect the expression of messenger RNA and embryonic development when measured in dioctenic acid (BCA); <br>In personal care and cosmetic applications, TEs can be used to protect the active ingredients in the formula from degradation; <br>TES solvent can be used to separate hemoglobin and protect the stability of hemoglobin after freeze-drying; <br>Finally, TES buffer can be used as cathode solution in 2-D gel isoelectric focusing electrophoresis (IEF). <br>Professional R &amp; D team can provide TES buffer samples for testing and detection according to customer requirements. <br> <br>TES Buffer (CAS No. 7365-44-8) Precautions <br>When detecting positive divalent copper ions, TES cannot be used because they will form a complex; <br>The buffer capacity is affected by temperature, and the configuration temperature should be controlled at room temperature; <br>TEs can affect the expression of messenger RNA and embryonic development; <br>There is little complexation between TEs and metal, but once complexation occurs, interference may occur; <br>Usually put it in a cool, dry and ventilated place to prevent tes crystal powder from getting wet; <br>After the solution is prepared, it should be prepared and used first. It is easy to produce impurities after long-term storage.
