Figure 1
Fig. 1
Interactions between thrombin, antithrombin and heparin. Thrombin (Factor IIa) exosite I: orientates fibrinogen binding and is important for platelet receptor (PAR) recognition; exosite II: binding site for heparin and fibrin, when fibrin is bound this blocks access for heparin. Antithrombin binds at the primary protease site.

An example of divergence between heparin concentration and measured ACT. ACT, activated clotting time; CPB, cardiopulmonary bypass.
