ABSTRACT:
Platelet-specific, chimeric immunoglobulin and immunoglobulin fragments are described. The chimeric molecules are made up of a nonhuman antigen binding region and a human constant region. Preferred immunoglobulins are specific for glycoprotein IIb/IIIa receptor in its complexed form; they block ligand binding to the receptor and prevent platelet aggregation. The immunoglobulins are useful in anti-thrombotic therapy when administered alone or in conjunction with thrombolytic agents, as well as in thrombus imaging.
