title: Solid-phase enzyme immunoassay of urokinase using monoclonal antibodies.
abstract: Using two monoclonal antibodies directed against urokinase, we have developed a micro enzyme-linked immunosorbant assay (ELISA) to detect and measure urokinase in biological fluids. The system presents the following characteristics: simple and rapid procedure, reproducibility, sensitivity (urokinase levels down to 1 ng/ml) and evaluation of the enzyme in biological fluids such as urine, pleural effusions, and ascitic fluids without preliminary purification.
