Used in biomedical research to quantify levels of uPAR protein in biological samples such as plasma, serum, and cell culture supernatants. This kit enables researchers to study the role of uPAR in processes like cell migration, tissue remodeling, and cancer progression. It is particularly valuable in oncology and immunology studies where uPAR expression correlates with tumor invasion, metastasis, and inflammation. The assay provides a sensitive and specific method to monitor uPAR concentration, supporting both clinical research and drug development efforts targeting the plasminogen activation system.
