1 Upon heparin infusion during cardiopulmonary bypass (CPB), a heparin releasable pool of endothelial associated TFPI circulates in plasma. Heparin tissue factor pathway inhibitor Homo sapiens
2 Upon heparin infusion during cardiopulmonary bypass (CPB), a heparin releasable pool of endothelial associated TFPI circulates in plasma. Heparin tissue factor pathway inhibitor Homo sapiens
3 Following protamine neutralization of heparin, the plasma TFPI level decreases, but does not return completely to baseline, suggesting that during CPB a fraction of the plasma TFPI becomes heparin-independent. Heparin tissue factor pathway inhibitor Homo sapiens
4 Following protamine neutralization of heparin, the plasma TFPI level decreases, but does not return completely to baseline, suggesting that during CPB a fraction of the plasma TFPI becomes heparin-independent. Heparin tissue factor pathway inhibitor Homo sapiens
5 RESULTS: The ELISA and Western blot data indicated that an increase in full-length TFPI accounted for most of the heparin releasable TFPI. Heparin tissue factor pathway inhibitor Homo sapiens
6 RESULTS: The ELISA and Western blot data indicated that an increase in full-length TFPI accounted for most of the heparin releasable TFPI. Heparin tissue factor pathway inhibitor Homo sapiens
7 Following heparin neutralization with protamine, the full-length TFPI antigen returned to baseline levels while the free TFPI antigen and the total plasma TFPI activity remained elevated. Heparin tissue factor pathway inhibitor Homo sapiens
8 CONCLUSIONS: During CPB the full-length form of TFPI is the predominant form in plasma because of its prompt release from the endothelial surface following heparin administration. Heparin tissue factor pathway inhibitor Homo sapiens
9 Upon heparin neutralization with protamine, full-length TFPI redistributes back to the endothelial surface. Heparin tissue factor pathway inhibitor Homo sapiens
