2. Application Scenarios
Reagent Kit Production: Custom-designed for automated blood analyzers, enabling precise detection.
Antithrombin Diagnostics: Accurately measures antithrombin concentration in blood samples to diagnose antithrombin deficiency.
Heparin Monitoring: Monitors heparin concentration in blood throughout surgery to ensure safety.
Anticoagulant Activity Detection: Evaluates the anti-FXa and anti-FIIa activities of unfractionated heparin and low molecular weight heparin, providing scientific support for anticoagulation therapy.
Activity Assessment: Detects the anti-FIIa activity of chemically synthesized compounds or tissue extracts, aiding in drug development and substance screening.
3. Reaction Principle
S-2238 is a specific substrate for thrombin, with a structure designed to mimic the N-terminal region of the alpha chain of fibrinogen. Chemically modified to enhance stability and reactivity, it plays a critical role in detection. During testing, excess thrombin is added to the plasma sample, where antithrombin forms a 1:1 complex with thrombin. The remaining thrombin reacts with the chromogenic group p-nitroaniline of S-2238, producing coloration. The intensity of the color correlates positively with residual thrombin and negatively with antithrombin. By measuring absorbance changes through spectrophotometry, the activity can be precisely determined.
4. Unique Advantages of S-2238
High Specificity and Stability: Ensures accurate and reliable experimental results.
High Sensitivity: Capable of detecting minor changes in AT-III activity.
Simple and Fast Operation: Reduces experiment time and lowers operational complexity.
Wide Applications: Suitable for both research laboratories and clinical settings, supporting multiple scenarios including cardiovascular diseases, blood disorders, and monitoring the efficacy of anticoagulant drugs.
