In the search for new ligands for the plasminogen kringle 4 binding-protein tetranectin, it has been found by ligand blot analysis andELISAthat tetranectinspecificallybound to the plasminogen-like hepatocyte growth factor and tissue-type plasminogen dissociation constants of these complexes were found to be within the same order of mag-nitude as the one for the plasminogen-tetranectin complex. The study also revealed that tetranectin did not interact with the kindred proteins: macrophage-stimulating protein, urokinase-type plasminogen activator and prothrombin
