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 extracellular matrix degradation and cell migration. It is widely applied in studies related to cancer progression, metastasis, inflammation, and tissue remodeling. Researchers use this assay to evaluate uPA expression under different experimental conditions, assess the effectiveness of therapeutic agents targeting the plasminogen activation system, and investigate the role of uPA in various disease models. The ELISA format allows for high-throughput, sensitive, and specific detection, making it a valuable tool in molecular and cellular research.
