Used in biomedical research to quantify urokinase plasminogen activator (uPA) levels in biological samples such as cell culture supernatants, serum, and tissue extracts. The kit enables accurate measurement of uPA, a key enzyme involved in fibrinolysis, extracellular matrix degradation, and cell migration. It is widely applied in studies related to cancer progression, metastasis, inflammation, and tissue remodeling. Due to its high sensitivity and specificity, this ELISA kit supports diagnostic research and drug development, particularly in oncology and cardiovascular diseases. It is intended for research use only and not for diagnostic procedures in humans.
