The chromogenic substrate TOOS reagent plays an important role in various detection fields due to its unique chemical properties. The color reaction it participates in can convert the presence and content of the target substance into visible or instrument measurable color changes, providing an intuitive and effective analytical tool for detection work.
In clinical biochemical testing, TOOS is commonly used to detect various metabolic products and enzyme activities in the human body. Taking blood glucose testing as an example, glucose oxidase catalyzes the reaction between glucose and oxygen, producing gluconic acid and hydrogen peroxide. Under the joint action of TOOS and peroxidase (POD), hydrogen peroxide will oxidize TOOS to generate quinone imine compounds with specific colors. By measuring the absorbance of the chromogenic product at a specific wavelength, the glucose content in the blood can be accurately calculated. This method has high sensitivity and specificity, and is widely used in clinical diagnosis in hospitals to help doctors quickly understand the blood sugar level of patients and provide an important basis for the diagnosis and treatment of diabetes and other diseases. In addition, in cholesterol detection, cholesterol esterase and cholesterol oxidase act on cholesterol in sequence, producing hydrogen peroxide, followed by TOOS participating in colorimetric reaction, achieving the determination of cholesterol content in serum, which is of great significance for evaluating the risk of cardiovascular disease.
TOOS is also indispensable in liver function testing. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) are important indicators reflecting liver cell damage. During the detection process, these two enzymes catalyze specific transamination reactions, producing hydrogen peroxide that undergoes color reactions in TOOS and POD systems. Based on changes in absorbance, the activity of ALT and AST can be accurately determined, thereby evaluating the health status of the liver and assisting in the diagnosis and monitoring of liver disease.
In addition to clinical biochemical testing, TOOS has also demonstrated significant value in the field of environmental monitoring. In water quality testing, TOOS can be used to detect certain pollutants in water. For example, for water samples containing phenolic compounds, under specific oxidation conditions, phenolic substances will react with TOOS to produce color products. By measuring the color depth, quantitative analysis of the content of phenolic pollutants in water can be achieved, providing data support for water pollution control. In addition, the TOOS-POD colorimetric system can also play a role in detecting the hydrogen peroxide content in water, helping to understand the redox status of the water and evaluate the safety of water quality.
TOOS, a chromogenic substrate, has wide and important applications in various fields such as clinical biochemical testing and environmental monitoring due to its efficient chromogenic performance. With the continuous development of detection technology, TOOS is expected to play a role in more detection projects, providing stronger support for people's health, environmental monitoring, and safety assurance.
