  • Publication number: 20130011868
    Abstract: 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.
