Used in biomedical research to quantify levels of urokinase-type plasminogen activator receptor (uPAR) in biological samples such as blood, plasma, or cell culture supernatants. This ELISA kit enables researchers to study uPAR's role in processes like cell migration, tissue remodeling, inflammation, and cancer progression. It is particularly valuable in oncology and immunology studies where uPAR expression correlates with tumor invasion, metastasis, and poor prognosis. The assay provides a sensitive and specific means to monitor uPAR concentration, supporting both basic research and biomarker validation in disease models.
