Abstract
Rabbits were repeatedly immunized with a chimeric plasminogen activator composed of the kringle-2 domain of human tissue-type plasminogen activator (t-PA) attached to the serine protease domain of the human urokinase-type plasminogen activator (u-PA). IgG from these rabbits was purified, biotinylated and subjected to affinity chromatography on K2tu-PA covalently attached to Sepharose. Roughly half the antibodies recovered from the K2tu-PA column could subsequently be bound to a column with similarly immobilized t-PA, whereas the other half bound to a u-PA column. Less than 0.01% of the biotinylated anti-K2tu-PA antibodies did not bind to either t-PA or u-PA and perhaps are directed against neoantigenic determinants on K2tu-PA, not present in the natural plasminogen activators.
