We have conjugated tirofiban, an antagonist of the GPIIb/IIIa integrin receptor, to PEG, and shown that these polymers effectively inhibit platelet aggregation. This inhibition decreased with the size of the polymer. Our goal was to develop new cryoprotective agents to store frozen platelets. Surprisingly, tirofiban-conjugated PEG did not exhibit any protection.
