PEGs (MW 300 and 1000) were further immobilized on this reactive surface. The PEGylated Tecothane™ surface was 40 Advances in Polyurethane Biomaterials then activated by a typical coupling reaction with BOC-protected lysine. Finally, the BOC-protecting group was removed by trifluoroacetic acid. The terminal NH2 on lysine preferentially captures plasminogen when exposed to blood. Plasminogen can be later converted into plasmin. Plasmin is believed to lyse fibrin, which binds platelets and participates in blood clotting.
