摘要: Abstract An inhibitor present in placenta and released placental tissue culture forms specific complexes with each of two molecular urokinase. Audoradiography demonstrated that the shifted electrophoretic position 125 I-labelled It did not change migration diisopropyl-fluorophosphate-inactivated urokinase, thereby indicating complex formation dependent on active serine site The had a strong neutralizing effect plasminogen activators from human ovarian carcinoma culture. might prove useful inhibiting fibrinolytic process necessary for proliferation tumour vessels.
