The new Trinder's reagent is a water-soluble aniline biosodium salt and hydrate, which has been frequently used in biological diagnostic reagents and biochemical detection. In the colorimetric determination of H2O2 activity, it has multiple incomparable advantages compared to conventional colorimetric reagents. At present, the new Trinder's reagents (chromogen substrates) contain products such as DAOS, HDAOS, MADB, MAOS, TOOS, TOPS, ADOS, ADPS, ALPS, etc. This series of product reagents is stable enough, and their reaction principles are basically similar, which can be used in detection systems for solving and experimental assembly lines. Among them, MAOS has a wide range of applications, and we will focus on understanding it. The full name of MAOS is N-ethyl-N - (2-hydroxy-3-sulfopropyl) -3,5-dimethylaniline sodium salt, which belongs to the new Trinder's reagent and has strong water solubility. It is a white powder. It plays a crucial role in many application fields, such as being a water-soluble reagent for enzymatic photometric determination of hydrogen peroxide and for detecting 4-AA coupled substrates. MAOS oxidation issue Trinder's reagent powder is not easily interfered with and oxidized, but when prepared as a solution, it is easily affected by air and produces red or yellow substances after oxidation. So after preparing the solution, it is necessary to seal and refrigerate it as much as possible, using as much as possible. Once the solution is exposed to high temperature air for a long time, it is highly susceptible to gradual oxidation, leading to discoloration of the solution. MAOS sensitive issues In addition, MAOS is extremely sensitive to light and humidity, so during storage, it needs to be refrigerated at a temperature between 0-10 degrees Celsius and frozen below 0 degrees Celsius. If there is no clear requirement for storage, the principle is to store it in a cool place below 15 ℃. Hubei Xindesheng focuses on the research and development of a batch of new Trinder's reagents, which have the characteristics of high water solubility, stable performance, high sensitivity, and loose requirements for pH range, ensuring the activity of multiple enzymes in the reaction. These have obvious advantages compared to other merchants, especially in terms of product supply, with spot goods shipped to ensure customer demand, while also providing comprehensive pre-sales and after-sales services, allowing customers to purchase with confidence!
