Advantages and storage of Maos in Trinder's reagent

The full name of Maos is n-ethyl-n - (2-hydroxy-3-sulfopropyl) - 3,5-dimethylaniline sodium salt monohydrate, which is a highly water-soluble aniline derivative of new Trinder's reagent. It plays an important role in it. Next, what are the advantages of Maos.

In the presence of hydrogen peroxide and peroxidase, the new Trinder's reagent formed very stable purple or blue dyes in the oxidative coupling reaction with 4-aminoantipyrine (4-AA) or 3-methylbenzothiazolylsulfonylhydrazone (MBTH).

The new Trinder's reagent is stable enough to be used in both solution and test line detection system.

It can be used as a water-soluble reagent for enzymatic spectrophotometric determination of hydrogen peroxide, as well as diagnostic detection and biochemical tests;

It is used for catalase spectrophotometric determination. It is only used for quantitative determination of uric acid (UA) in human serum, plasma or urine. It has good water solubility, high sensitivity and strong stability.

The molar absorptivity of Maos is high, so its sensitivity is also high. It should be noted that Maos will fade when the detection time is too long, so the detection of Maos needs to be completed in time and cannot be interrupted.

But Maos is sensitive to light and humidity. Therefore, when we store, the temperature of cold storage is between 0-10, and the temperature of frozen storage is below 0. If the storage temperature is not indicated, in principle, it is best to keep it in a cool place below 15. In principle, the service life of the product is because the reagent will change with time due to the storage conditions or the mixed trace impurities. Therefore, it is difficult to strictly determine the service life or shelf life.

The Maos oxidation chromogen reagent produced by Desheng has high water solubility and stable aniline analogues. The pH range of oxidation reaction is very wide, and the purity is more than 99%. The process is stable, the sensitivity is high, and the stock is sufficient, and samples are provided.
