Heparin Binds Plasma Proteins; Angiomax® (bivalirudin) Binds Specifically to Thrombin Heparin (long strand) binds to other plasma proteins (colored molecules) and platelets, reducing heparin’s availability to bind to AT. Heparin-binding proteins are elevated in acute coronary syndromes (ACS). Angiomax (bright blue) binds onlyto thrombin (orange). Angiomax is not neutralized by other plasma proteins or platelets; it remains fully active near thrombus. Weitz JI et al. Thromb Res. 2002;106:V275-V284. Wittkowsky AK.
