With the rapid development of China's economy in the 21st century, people's living conditions have made a qualitative leap compared to the 20th century. However, while the material conditions are extremely rich, due to excess nutrition, lack of exercise and other reasons, rich diseases such as diabetes, hypertension and hyperlipidemia have also begun to spread. In order to better and more convenient for people to monitor and diagnose these diseases, a variety of diagnostic and therapeutic instruments that can be used for bedside diagnosis, such as blood glucose meters, multiple lipid test cards, and triglyceride test strips, have been developed in succession. Today we are going to talk about MAOS is a core material that can be used with blood glucose test paper, total cholesterol test paper and the other two test papers mentioned above.
The maximum absorption wavelength and molar absorbance of the new Trinder’s reagent
MAOS(CASNo.:82692-97-5)full name: N-ethyl-N-(2-hydroxy-3-sulfopropyl)-3,5-dimethylaniline sodium salt monohydrate, is a new Trinder's A very important member of the reagent family. It is not as commonly used as TOOS, but it also has an absolutely irreplaceable role. As can be seen from the figure below, the maximum absorption wavelength of MAOS is 630nm, which has a larger absorption wavelength than other Trinder’s reagents. Since Trinder's reaction principle is the hydrogen peroxide produced by the tested substance under the action of the enzyme, then 4-aminotepyrine and catalase oxidize the chromogen substance to a red quinoid substance, and then use light absorption method to determine the Measured substance concentration.
The scope of application of MAOS and other Trinder's reagents is almost the same, between PH 5.0 and 9.5, but the maximum absorption wavelength of MAOS makes it can greatly reduce the interference of other components in the sample to be tested, so it is widely used in the need for relatively accurate Numerical applications such as blood glucose test strips.
