  • Inhibition of coagulation in blood and blood products
    Patent number: 6566140
    Abstract: The present invention provides methods for inhibiting blood clotting. In general, the methods include adding corn trypsin inhibitor (CTI) to blood or a blood product in an amount sufficient to inhibit the clotting. The CTI can be used alone or in combination with other anti-coagulants. In one aspect, the invention features plasma clotting assays featuring substantially prolonged clotting times. Clotting assays using whole or minimally altered blood are also provided. Further provided are methods for storing blood or blood products at low temperature with the CTI.
