TOOS is a new type of Trinder's reagent, widely used for in vitro diagnosis in medical testing. Its appearance is white crystal powder, and its Chinese name is relatively long. It is N-ethyl-N - (2-hydroxy-3-sulfopropyl) -3-methylaniline sodium salt, corresponding to CAS number 82692-93-1. When communicating with peers, we prefer to directly use the English name TOOS or CAS number to determine whether we are discussing the same product. The TOOS reagent detection method, also known as enzymatic method, requires water dissolution before use. Its detection principle is to produce hydrogen peroxide between the sample to be tested and the corresponding enzyme, and the hydrogen peroxide then acts together with 4-aminoantipyrine (4-AAP) and peroxidase (POD) to generate red quinone imine compounds from the chromogenic substance, i.e. TOOS aqueous solution. The absorbance of the substance is measured to calculate the waiting value. So, what items can this method detect? In fact, when conducting tests in hospitals, blood sugar testing items, routine liver function tests, triglyceride and lipid testing, cholesterol testing, and other items are all carried out through TOOS testing reagents. I believe everyone has discovered that these items are metabolites in the body, and their analysis can provide important information and decision-making basis for the diagnosis and treatment of diseases. However, when using TOOS reagent, special attention should be paid to its reducibility. After it is configured as a solution, if it is placed in the air, it will undergo oxidation and discoloration. Therefore, it is necessary to use it as soon as possible to achieve maximum utilization. The editor also suggests choosing powdered raw materials when purchasing, in order to ensure the expected experimental results are achieved during use. The TOOS crystal powder produced by Desheng Biochemical not only has a material purity of over 99%, but also has a high color purity. Impurity in color directly affects the color development results. In addition, Desheng Biochemical has a dedicated quality monitoring officer to track and supervise the entire production process, ensuring that each production process is accurately carried out. Desheng Biochemical is also a direct manufacturer of color substrate TOPS, ADOS, ADPS, ALPS, DAOS, HDAOS, MADB, and MAOS, Not an intermediary, we provide you with high-quality products and save costs.
