Prevention of thrombin/antithrombin III reaction in the presence of protamine or polybrene.
The rate of the thrombin/antithrombin III (AT III) reaction was decreased in the presence of free polybrene or protamine. The reaction rate was also decreased in protamine-coated tubes and tubes on which polybrene was absorbed nonspecifically. The reaction was also prevented when either thrombin or AT III was transferred into noncoated tubes after instantaneous contact with protamine-coated tubes or tubes with polybrene. These facts suggest that the thrombin/AT III reaction rate is determined with concentrations of reactive protein species.
