Abstract
The present invention provides a conjugate wherein GP (glycoprotein) Ib and a lipid are bonded via polyalkylene oxide. The present invention also provides a complex (GPIb lipid complex) containing this conjugate and a free lipid. The GPIb lipid complex is expected to have a potential for practical application in a wide range, as a platelet substitute, a pharmaceutical agent for the prophylaxis or treatment of angiopathy, vascular damage and thrombosis, a diagnostic for vWF deficiency and the like, a biological or medical reagent, a reagent for screening platelet aggregation suppressant or antithrombosis, and the like. The GPIb lipid complex of the present invention is also useful as a diagnostic for finding the location of vascular lesion or thrombus formation, or a therapeutic agent thereof. Moreover, the GPIb lipid complex of the present invention is also superior in retention property in blood, which enables continuous expression of a pharmacological action. The conjugate of the present invention is highly utilizable as an active ingredient of the GPIb lipid complex of the present invention.
