TOPS is used for liver function biochemical test kit

TOPS, as the new Trinder's reagent, is a highly water-soluble derivative of aniline and is widely used in in vitro diagnostic kits, especially playing an important role in liver function biochemical kits. The following is a detailed analysis of the application of TOPS in liver function biochemical test kits:

Basic characteristics of TOPS

TOPS, as a chromogenic substrate, has high water solubility and sensitive chromogenic reaction characteristics. In biochemical testing of liver function, it can react with specific enzymes or substrates to produce easily detectable color changes, thereby achieving quantitative determination of liver function related indicators.

Application of TOPS in Liver Function Biochemical Test Kit

1. Testing indicators

Adenosine deaminase (ADA): TOPS is one of the main components of adenosine deaminase detection reagents. Adenosine deaminase is a sensitive indicator reflecting liver injury, and its elevated level often indicates liver cell damage or necrosis. The colorimetric reaction involving TOPS can accurately determine the activity of adenosine deaminase in serum, providing reliable basis for the evaluation of liver function.

Other liver function indicators: Although TOPS has a prominent application in adenosine deaminase detection, it may also be used for the detection of other liver function indicators, such as transaminase (ALT, AST), total bilirubin (T-Bil), direct bilirubin (D-Bil), etc. The changes in these indicators can reflect liver function abnormalities such as liver cell damage and bile stasis.

2. Reaction principle

The reaction principle of TOPS in liver function biochemical assay kit is mainly achieved through its color development characteristics. When TOPS reacts with specific enzymes or substrates, it produces specific color changes. By measuring the degree of color change (such as absorbance value), the content or activity of the measured substance can be indirectly calculated.

3. Advantages

High sensitivity: TOPS is sensitive to color and can accurately reflect trace changes in liver function indicators.
Quick response: TOPS participates in a fast color reaction, which helps to shorten the detection time.

High precision: TOPS's color reaction system is stable, minimally affected by external interference, and the detection results are accurate and reliable.

Practical application cases

In practical applications, TOPS is often used to prepare the chromogenic substrate portion in liver function biochemical assay kits. For example, when detecting the activity of adenosine deaminase in serum, a colorimetric substrate containing TOPS can be used to react with the serum sample, and the activity of adenosine deaminase can be calculated by measuring the color change of the reaction product. In addition, TOPS may also be used in detection kits for other liver function indicators to provide comprehensive liver function assessment.

Summary

TOPS reagent, as a novel Trinder's reagent, plays an important role in liver function biochemical assay kits. Its high water solubility, sensitive color reaction characteristics, and stable reaction system make it an indispensable reagent in liver function testing. Through the color reaction involving TOPS, the content or activity of various liver function related indicators in serum can be accurately determined, providing reliable basis for the evaluation of liver function.
