Abstract
Antibodies and antigen-binding antibody fragments that bind to GPIIb/IIIa and chimeric polypeptides comprising these binding molecules are disclosed. Some of these antibodies and antigen-binding antibody fragments preferentially bind GPIIb/IIIa on activated platelets while others do not show a preference for binding GPIIb/IIIa on resting versus activated platelets. Some of these antibodies and antibody fragments do not inhibit the interaction of GPIIb/IIIa with fibrinogen, while some others do. The disclosed antibodies do not induce platelet activation. Some of these antibodies and antigen-binding antibody fragments are useful in targeting therapeutic agents such as clotting factors to platelets while others are useful in reducing platelet aggregation and/or thrombus formation.
