Application of uricase 9002-12-4 in in vitro diagnostic kit

As an end product of purine metabolism, abnormal concentration of uric acid is closely related to diseases such as gout, renal dysfunction, and metabolic syndrome. In the field of in vitro diagnostics, uricase has become the core component of uric acid detection kits due to its high specificity, strong catalytic activity, and stability. This article will analyze how uricase empowers modern medical testing from four dimensions: mechanism of action, technological pathway, colorimetric system, and clinical value.  

Molecular damage mechanism of freeze-thaw cycles

Uricase is an oxidoreductase that specifically catalyzes the breakdown of uric acid into uracil, carbon dioxide, and hydrogen peroxide. Its core advantages lie in:

Uricase

1. High specificity: only acts on the C-N bond in uric acid molecules, avoiding cross reactions with other biomolecules and ensuring the accuracy of detection results;  

2. Strong catalytic activity: can quickly decompose uric acid at room temperature, shortening detection time;  

3. Stability: Can maintain activity for a long time under suitable conditions, suitable for the production and storage needs of the reagent kit.  

Technical path: Collaborative innovation of dual enzyme coupling method and uricase method

The current mainstream uric acid detection technology is centered around uricase, which amplifies and converts signals through different enzymatic reactions

1. Uricase peroxidase coupling method: uricase catalyzes the generation of hydrogen peroxide from uric acid, which reacts with 4-aminoantipyrine (4-AAP) and chromogenic agents (such as TOPS) under the action of peroxidase (POD) to form a red quinone imine compound. The absorbance of this product is linearly positively correlated with uric acid concentration, making it suitable for batch detection in fully automated biochemical analyzers.  

2. Urinase method: Urinase directly catalyzes the decomposition of uric acid, and indirectly determines the uric acid content by monitoring changes in pH or carbon dioxide production in the reaction system. This method is easy to operate, cost-effective, and suitable for rapid screening in primary healthcare institutions. The collaborative application of two technological paths covers the full scenario requirements from laboratory precision testing to on-site rapid diagnosis.

Color System: Breakthrough Application of TOPS

In the uricase peroxidase coupling method, the performance of the color reagent directly affects the detection sensitivity and stability. A new colorimetric reagent represented by TOPS (N-ethyl-N - (3-sulfopropyl) -3-methylaniline sodium salt) has greatly improved the sensitivity of uric acid detection due to its high water solubility, strong stability, and anti-interference ability.  

Clinical value: from disease diagnosis to health management

The uricase driven in vitro diagnostic kit has demonstrated multiple values in clinical practice:

1. Disease diagnosis: Serum uric acid level is the core indicator for diagnosing gout and an important reference for renal function assessment and metabolic syndrome warning;  

2. Treatment monitoring: By dynamically monitoring uric acid levels, guiding gout patients to adjust the dosage of uric acid lowering drugs and evaluate treatment effectiveness;  

3. Health management: In physical examination scenarios, uric acid testing can identify high-risk populations and promote lifestyle interventions and disease prevention.
