Used in biomedical research to quantify urokinase plasminogen activator (uPA) levels in cell culture supernatants, plasma, serum, and other biological fluids. Helps in studying processes involving fibrinolysis, tissue remodeling, and cell migration. Widely applied in cancer research, particularly in understanding tumor invasion and metastasis, as uPA is often overexpressed in malignant tissues. Also used in cardiovascular research to assess thrombolytic activity and monitor disease progression. The kit enables high-sensitivity detection, supporting both clinical and experimental investigations into diseases where uPA system dysregulation plays a key role.
