Application of New Triners Reagent-- MAOS

Release time:


The Chinese name of MAOS is N-ethyl-N- (2-hydroxy-3-sulfopropyl) -3,5-dimethylaniline sodium salt monohydrate, which is a white powder whose CAS No. is 82692- 97-5. This product is relatively sensitive to light and humidity. Therefore, our storage requirements are high, and we need to use a light-shielded and well-sealed container. The temperature should be guaranteed at 0-5℃. It should be protected from light and moisture to ensure that the quality of detection is more accurate and higher.

Usage: It can be applied to water-soluble reagents for the determination of hydrogen peroxide by enzyme photometry, as well as diagnostic tests and biochemical tests.

MAOS chromogenic substrate reagent

Application: The new Trinder's reagent is a highly water-soluble aniline derivative, which is widely used in diagnostic tests and biochemical tests. It has several advantages over conventional chromogenic reagents in the chromogenic determination of hydrogen peroxide activity. The new Trinder's reagent is stable enough to be used in both solutions and test line inspection systems. In the presence of hydrogen peroxide and peroxidase, the new Trinder's reagent reacts with 4-aminoantipyrine (4-AA) or 3-methylbenzothiazole sulfone hydrazone (MBTH) during the oxidative coupling reaction. Forms a very stable purple or blue dye. The molar absorbance of the coupling dye with MBTH is 1.5-2 times higher than that with 4-AA; however, the 4-AA solution is more stable than the MBTH solution. The substrate is enzymatically oxidized by its oxidase to produce hydrogen peroxide. The concentration of hydrogen peroxide corresponds to the substrate concentration. Therefore, the amount of substrate can be determined by the chromogenic of the oxidative coupling reaction. Glucose, alcohol, acyl-CoA and cholesterol can be used to detect those substrates coupled with the new Trinder's reagent and 4-AA. There are 10 new Trinder's reagents. Among the new Trinder's reagents, TOOS is the most commonly used.

However, for specific substrates, testing different types of new Trinder's reagents is necessary to develop the best detection system.
