For enzyme-linked immunosorbent assay (ELISA) determination of soluble uPA and PAI-1 antigens, supernatants were collected from the 3D tube formation assay 72 hours after stimulation and assayed as previously described [24,36]. The monoclonal uPAR-blocking antibody H-2 came from Boehringer Mannheim, Penzberg, Germany [37] and was used to determine the overall internalization of the uPA:PAI-1 complex by blocking the uPA binding to uPAR, as previously described [26].
