What items can the chromogenic substrate TOOS be used for?

TOOS is a new type of Trinder's reagent, a chromogenic reagent widely used in in vitro diagnosis in medical tests. The appearance is white crystalline powder. Its Chinese name is relatively long, N-ethyl-N-(2-hydroxy-3- Sulfopropyl)-3-methylaniline sodium salt, the corresponding CAS number is 82692-93-1. When communicating with colleagues, we prefer to directly use the English name TOOS or CAS number to determine whether we are talking about the same product.

The method of TOOS reagent detection is also called enzymatic method, which needs to be used after being dissolved in water. Its detection principle is that the sample to be tested and the corresponding enzyme produce hydrogen peroxide, and the hydrogen peroxide reacts with 4-aminoantipyrine (4-AAP) and peroxidase (POD) to make the chromogen The substance, that is, the TOOS aqueous solution, generates a red quinoneimine compound, and the absorbance of the substance is measured to calculate the pending value.

So, what items can such a method detect? In fact, when testing in the hospital, blood glucose testing items, routine liver function tests, triglyceride blood lipid testing, cholesterol testing and other items are all carried out by TOOS testing reagents. I believe everyone has already discovered that these items are all metabolized in the body. The analysis of them can provide important information and decision-making basis for the diagnosis and treatment of diseases.

However, when using TOOS reagent, it is necessary to pay special attention to its reducibility. After configuring it into a solution, if it is placed in the air, it will cause oxidation and discoloration. use. The editor also recommends choosing powdered raw materials when purchasing, so as to ensure the expected experimental effect when used.

The TOOS crystal powder produced by Desheng Biochemical not only has a material purity of more than 99%, but also has high color purity. Impure color will directly affect the color development results. Track and supervise to ensure that each production link is carried out accurately.
