Abstract:
The effect of polymethacrylic acid on the reaction between thrombin and antithrombin-III was investigated. It was found that polymethacrylic acid accelerated the inactivation rate of thrombin by antithrombin-III, whereas this polyanion did not affect thrombin activity. It is suggested that polymethacrylic acid may simulate the action of heparin on thrombin and antithrombin-III.
