Platelet-specific chimeric immunoglobulin

Abstract From the Canadian patent

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 alone or in conjunction with thrombolytic agents and in thrombus imaging.
