Used in cancer research and therapy development due to its ability to target the uPAR (urokinase plasminogen activator receptor), which is overexpressed in various tumor types. It helps inhibit tumor cell invasion, metastasis, and angiogenesis by blocking uPAR-mediated signaling pathways. This antibody is also employed in diagnostic applications to detect uPAR expression in tissue samples, aiding in cancer prognosis. Its high specificity makes it valuable in immunoassays and flow cytometry for studying cell surface uPAR distribution. Additionally, it serves as a reference standard in the development of other anti-uPAR antibodies and therapeutic agents.
