The new Trinder's reagent is a highly water-soluble aniline derivative that has been widely used in diagnostic tests and biochemical tests. In the colorimetric determination of hydrogen peroxide activity, it has many advantages compared with conventional color reagents. The new Trinder's reagents are stable enough to be used in solutions and test line inspection systems.
Currently chromogen substrates (new Trinder's reagents) include TOOS, TOPS, ADOS, ADPS, ALPS, DAOS, HDAOS, MADB, MAOS, etc. These new chromogens actually have similar reaction principles to traditional chromogens, but they have more advantages. We mainly understand the MAOS among them.
The full name of MAOS is N-ethyl-N-(2-hydroxy-3-sulfopropyl)-3,5-dimethylaniline sodium salt. It is a highly water-soluble aniline derivative of the new Trinder's reagent. Which has a pivotal position. It is a water-soluble reagent that can be applied to the enzymatic photometric determination of hydrogen peroxide, and is widely used in diagnostic testing and biochemical tests.
Reasons for the discoloration of the reagent solution: Color-developing substrates such as MAOS are all new Trinder's reagents, which are derivatives of highly water-soluble aniline sodium salt, which will produce red or yellow substances after being oxidized. Trinder's reagent powder is not easy to be oxidized. It needs to be sealed and refrigerated after preparation. If the solution is exposed to the air for a long time and the temperature is high, they may be slowly oxidized by the oxygen in the air. Discoloration of the solution occurred.
MAOS is sensitive to light and sensitive to humidity. Therefore, when we store, the storage temperature of cold storage is between 0-10, and the temperature of frozen storage is below 0. If the storage temperature is not specified, in principle, it should be stored in a cool place below 15C.
Hubei Xindesheng has focused on the research and development of a batch of new Trinder's reagents and other color reagents. The new reagent has more advantages: such as high water solubility, UV absorption of the color reaction product> 540nm; color reaction requires a wide pH range, and the activity of a variety of enzymes can be guaranteed during the reaction; color reaction sensitivity is higher and can be used For the determination of very small amounts of analytes.
And it has considerable product advantages, purity: >99%, good water solubility, stable process, and can ensure the appearance of the product is pure white crystal powder. Welcome everyone to inquire.
