Chromogen substrate tops manufacturer

Details:

The full Chinese name of TOPS is n-ethyl-n - (3-sulfopropyl) - 3-methylaniline sodium salt. Its CAS No. 40567-80-4, molecular formula is c12h18nnao3s · H2O and molecular weight is 297.34. It can be used as a water-soluble reagent for the determination of hydrogen peroxide by enzymatic spectrophotometry and is widely used in diagnostic detection and biochemical tests.

Pictures of tops products

Desheng's top products have three advantages:

1. Desheng has been adhering to the company culture of taking morality as the foundation, honesty as the first, quality first and leading technology. It is specialized in the R & D, production and sales of blood collection additives, in vitro diagnostic reagents, buffers and luminescent substrates. And there is a special R & D department, so Desheng products are supplied by top manufacturers with preferential prices and no price difference.

2. Desheng products are ready to use and can be packaged according to customers' needs. And the sub packaging process is strict. It is carried out at the professional sub packaging table. The sub packaging table is kept clean. The sub packaging personnel must wear disposable gloves for sub packaging, and the clothing requirements of the staff are more strict.

3. Desheng delivered goods quickly. It ordered goods on the same day and delivered goods on the same day (before 4 o'clock). With the concept of customer-oriented, the staff once had a customer with a very large order, but the sub packaging was cumbersome. The company ensured that the customer's order was delivered on time, and all the staff helped to sub package to ensure the delivery of products.

Application of tops:

Biochemical research. Water soluble reagent for the determination of hydrogen peroxide by enzymatic spectrophotometry. The new Trinder "s reagent is a highly water-soluble aniline derivative, which is widely used in diagnostic detection and biochemical test. It has several advantages over the conventional chromogenic reagent in the colorimetric determination of hydrogen peroxide activity. The new Trinder" s reagent is stable enough to be used in both solution and test line detection system. In the presence of hydrogen peroxide and peroxidase, The novel Trinder "s reagent is used with 4-aminoantipyrine (4-AA) or 3-methylbenzothiazole sulfone hydrazone (MBTH) During the oxidative coupling reaction, very stable purple or blue dyes are formed. The molar absorbance of the dye coupled with MBTH is 1.5-2 times higher than that of the dye coupled with 4-AA; However, 4-AA solution is more stable than 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 color development of oxidation 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 kinds of new Trinder" s reagents is necessary to develop the best detection system.

Tops is stored at 0-5 ℃, protected from light and moisture, with purity > 99%, good water solubility and stable process, which can ensure that the product appearance is pure white crystal powder. Desheng is an old blood testing reagent company with 14 years of R & D and production experience, and has deep research on chromogen substrate Trinder's reagent.
