Abstract
A method of analyzing an exosome is provided for detecting abnormality in a cell, including: (a) a step of preparing an exosome from a sample; (b) a step of bringing the exosome prepared in the step (a) into contact with a first antibody to a protein which exists on the surface of the exosome as an antigen and forming a first antibody-exosome complex; and (c) a step of measuring a zeta potential of the first antibody-exosome complex.
