Used in biomedical research to quantify rabbit tissue plasminogen activator (t-PA) levels in biological samples such as plasma, serum, or tissue extracts. This ELISA kit enables researchers to study fibrinolysis, the body's natural process of breaking down blood clots, in experimental models involving rabbits. It is particularly valuable in cardiovascular research, including studies on thrombosis, stroke, and the efficacy of thrombolytic therapies. The assay provides a sensitive and specific measurement of t-PA antigen concentration, supporting investigations into vascular biology, inflammation, and endothelial function. Commonly used in preclinical studies to evaluate drug effects on the fibrinolytic system.
