METHOD OF PREPARING AMYLOID BETA PROTEIN HAVING HIGH TOXICITY

摘要

PROBLEM TO BE SOLVED: To provide a self-association type amyloidβprotein which has high toxicity equivalent to that of a self-association type amyloidβprotein existing in the living body of a patient suffering from Alzheimer's disease or the like, and maintains the toxicity. SOLUTION: This method is for producing the self-association typeβ-amyloid protein which has high toxicity, characterized by including a process for circulating an aqueous solution ofβ-amyloid protein, and the self-association type amyloidβprotein has high toxicity and is obtained by the method.
