Used to measure the functional activity of human alpha-2-antiplasmin (α2-AP) in plasma samples. This assay is commonly applied in research settings to assess fibrinolytic system status, particularly in studies related to thrombosis, bleeding disorders, and liver disease. It helps evaluate α2-AP's ability to inhibit plasmin, providing insight into clot stability and fibrinolysis regulation. The kit is suitable for monitoring changes in α2-AP activity during disease progression or treatment, and is widely used in clinical laboratories and biomedical research.
