EcarinEcarin is a metalloprotease isolated from the venom of the saw-scaled viper (Echis carinatus) that activates prothrombin. Ecarin does not affect other clotting factors. The action of ecarin on prothrombin is independent of calcium, phospholipids and factor V. Moreover, Ecarin, in contrast to factor Xa, activates the acarboxy form of prothrombin present in plasma of patients undergoing oral anticoagulant therapy with vitamin K antagonists. Determination of prothrombin levels in patients undergoing anticoagulant therapy. Based on the interaction of hirudin with meizothrombin a simple ecarin clotting test for the monitoring of hirudin levels has been developed (Nowak and Bucha, 1993). Due to its action on acarboxy prothrombin, ecarin can be used for the determination of acarboxy prothrombin in the supernatent of barium sulfate treated patient plasma where normal carboxylated prothrombin has been removed by adsorption. Ecarin can be used for the detection of low prothrombin concentrations in plasma fractions for quality- and in-process control purposes. Ecarin, used in conjunction with the phospholipid- and calcium ion-dependent prothrombin activator Textarin from Pseudonaja textilis venom, forms a highly sensitive and specific test system for lupus anticoagulant (Triplett et al., 1993). |
