title: Heparin-like tubings. III. Kinetics and mechanism of thrombin, antithrombin III and thrombin-antithrombin complex adsorption under controlled-flow conditions.
abstract: In previous papers, we described treated tubular materials which exhibit an heparin-like antithrombic activity under dynamic conditions. In order to ascertain the heparin-like mechanism of this activity, we have studied the interactions of thrombin, antithrombin III and thrombin-antithrombin III complex with the inner face of these treated tubings under controlled-flow conditions. Moreover, the kinetics of the adsorption of thrombin were studied at different flow rates to establish the rate-determining step.
