UROKINASE PLASMINOGEN ACTIVATOR (urokinase, uPA) is a key serine protease involved in the degradation of the extracellular matrix that catalyzes the conversion of plasminogen to active plasmin. It acts as a thrombolytic agent to break up blood clots and when over-expressed, has been reported to influence the growth of certain malignant tumors (breast, prostate, etc.). BioAssay Systems’ DUKI-100 Kit provides a convenient fluorimetric means to screen for potential urokinase inhibitors. In this assay, the fluorimetric substrate reacts with urokinase and an inhibitor will decrease the fluorescence at λex/em = 380/450 nm.
