  • Publication number: 20140248657
    Abstract: The purpose of the present invention is to develop a method for producing a large amount of an insoluble aggregate that is equivalent to an insoluble aggregate formed in the brain of a patient. A method of producing an insoluble aggregate of a neurodegenerative-disease-related protein according to the present invention comprises the steps of: (1) introducing an insoluble fraction originated from the brain of a neurodegenerative disease patient into a cultured cell in which the neurodegenerative-disease-related protein can be expressed in a constitutive manner; (2) culturing the cultured cell into which the insoluble fraction has been introduced; and (3) extracting separating an insoluble fraction from the cultured cell. Optionally, the method may additionally comprise a step of amplifying the insoluble aggregate of the neurodegenerative-disease-related protein in the cultured cell.
