Used in biomedical research to quantify levels of human tissue-type plasminogen activator (t-PA) in biological samples such as plasma, serum, or cell culture supernatants. This ELISA kit enables researchers to study t-PA's role in fibrinolysis, thrombosis, and cardiovascular diseases. It is also applied in clinical research settings to assess endothelial function and monitor conditions involving abnormal clot breakdown, such as stroke, deep vein thrombosis, or metabolic syndrome. The assay provides a sensitive and specific method for detecting t-PA antigen concentrations, supporting both diagnostic development and therapeutic monitoring in experimental models.
