Basic Information
There are 10 kinds of the new Trinder's reagents in common use, and the molar absorbance and absorbance wavelength of each chromogenic substrate will be different, and there will be differences in the selection of different characteristics.TOPS is commonly used for colorimetric determination of uric acid and cholesterol.It has good water solubility, high sensitivity, high purity (>99%), strong process stability, and can be used in both solution and test pipeline detection system.The water-soluble reagent for the determination of hydrogen peroxide by enzymatic photometry is widely used in diagnostic detection and biochemical tests.
TOPS POWDER
TOPS also has certain requirements in storage. 1. Its water solubility determines that it must be operated in a sealed environment and in a dehumidified environment, otherwise it is very easy to absorb moisture leading to changes in its chemical properties.2. Package the product in light-proof bottles because it is sensitive to light.3. The temperature should be kept at 0-5 C.

Usage
Usage: Reagent for determination of hydrogen peroxide by enzymatic photometry.
The new Trinder's reagent is a highly water-soluble aniline derivative, which is widely used in diagnostic tests and biochemical tests.There are several advantages over conventional chromogenic reagents in the colorimetric determination of hydrogen peroxide activity.The new Trinder's reagent is stable enough to be used both in solution and in test pipeline detection systems.In the presence of hydrogen peroxide and peroxidase, new Trinder's reagents form very stable purple or blue dyes during the oxidative coupling reaction with 4-aminoantipyrine (4-AA) or 3-methylbenzothiazole sulfone hydrazone (MBTH).The molar absorbance of dyes coupled with MBTH is 1.5-2 times higher than that of dyes coupled with 4-AA; however, the 4-AA solution is more stable than that of MBTH solution.Substrates are enzymatically oxidized by their oxidase to produce hydrogen peroxide.This concentration of hydrogen peroxide corresponds to the substrate concentration.Therefore, the amount of the substrate can be determined by the color development of the oxidative coupling reaction.Glucose, alcohol, acyl-coenzyme A and cholesterol can be used to detect those substrates coupled with the new Trinder's reagent and 4-AA.
