  • METHOD FOR ASSISTING WITH DIAGNOSIS OF ALZHEIMER'S DISEASE OR MILD COGNITIVE IMPAIRMENT, BIOMARKER, REAGENT KIT, AND DEVICE
    Publication number: 20220291242
    Abstract: A method for assisting the diagnosis of Alzheimer's disease, comprising: measuring an amount of extracellular vesicles having phosphatidylserine and tetraspanin, or the amount of extracellular vesicles having phosphatidylserine and tetraspanin and an amount of extracellular vesicles having tetraspanin, in a biological specimen derived from a subject; and determining that the subject has Alzheimer's disease using the amount of extracellular vesicles having phosphatidylserine and tetraspanin, or a ratio of the amount of extracellular vesicles having phosphatidylserine and tetraspanin to the amount of extracellular vesicles having tetraspanin as an indicator.

  • STORAGE STABILIZER FOR EXTRACELLULAR VESICLE AND STORAGE STABILIZATION METHOD FOR EXTRACELLULAR VESICLE
    Publication number: 20220033765
    Abstract: An object of the present invention is to provide a means capable of stably storing an extracellular vesicle. The present invention relates to a storage stabilizer for an extracellular vesicle, which contains a copolymer containing a monomer unit derived from vinylpyrrolidone and a monomer unit derived from vinyl acetate, or a polymer having a monomer unit derived from vinylpyrrolidone such as polyvinylpyrrolidone and relates to a storage stabilization method for an extracellular vesicle, which includes cryopreserving an extracellular vesicle in the presence of the polymer.
