The present invention provides an antibody which has the following features, its active fragment, or a derivative thereof: a) It specifically binds to human platelet membrane glycoprotein VI (GPVI); b) The function to activate a platelet and/or the function to induce a thrombocytopenia in vivo are low; and c) It at least partially depletes GPVI on the platelet membrane by contacting with a platelet.

Anti-platelet membrane glycoprotein VI monoclonal antibody

The present invention provides an antibody which has the following features, its active fragment, or a derivative thereof:

The present invention provides a convenient and highly sensitive method of determining sGPVI present in plasma; this is accomplished by establishing a plurality of mouse hybridomas that produce antibody against GPVI and combining the antibodies produced therefrom. Provided thereby are a novel platelet activation marker, a reagent and method for determining this novel platelet activation marker, and novel applications of this marker in, for example, the diagnosis of diseases associated with platelet activation/vascular endothelial injury.
