摘要

The purpose of the present invention is to provide a method for separating a vesicle having a lipid bilayer membrane, the method having excellent efficiency of impurity removal, and the method not being prone to rupture a vesicle having a lipid bilayer membrane. A method for separating a vesicle having a lipid bilayer membrane, the method characterized by including a complex-forming step for bringing a biological sample including a vesicle having a lipid bilayer membrane into contact with a solid-phase carrier to which is bound a ligand for recognizing a surface antigen present on a surface of the vesicle and forming a complex of the vesicle and the solid-phase carrier, and a washing step for washing the complex, at least the complex-forming step or the washing step being performed in the presence of a nonionic surfactant.
