The Chinese name of the in vitro diagnostic reagent TOOS is N-ethyl-N - (2-hydroxy-3-sulfopropyl) -3-methylaniline sodium salt, which belongs to the chemical intermediate. Its appearance is a white crystalline powder, which is used after water dissolution. TOOS has become a commonly used colorimetric reagent in in vitro diagnostic reagents due to its high sensitivity and stable performance. So how is TOOS used? When conducting physical examinations in hospitals, many projects rely on analyzing changes in relevant metabolites in the body, searching for characteristic biomarkers, and establishing corresponding detection methods. Provide biochemical information and decision-making basis for disease prevention, diagnosis, and treatment. The liver function, kidney function, blood sugar, blood lipids, and other commonly performed tests in hospitals belong to biochemical diagnosis. TOOS is mainly used for measuring the concentration of uric acid in human serum, plasma, or urine by catalase spectrophotometry. It has shown advantages such as good color rendering effect, rapid response, stability, and high precision in blood glucose testing and routine liver function testing. In addition, it can also be used as a diagnostic reagent for blood lipid testing such as triglycerides and cholesterol testing. When using TOOS, it should be noted that it has reducing properties. If the prepared solution is exposed to air, it may undergo oxidation and discoloration. It is recommended to prepare it as needed to avoid wasting raw materials. When purchasing, choose powdered raw materials to ensure good experimental results during use. The TOOS produced by Desheng Biochemical not only has a purity of 99%, but also has a pure white crystalline powder appearance (if the color is impure, it will have a significant impact on color development). The crystal shape is full. We have been favored by over 100 domestic and foreign customers, and have also received a large number of repeat customers.
