The present invention relates to a method for assaying soluble GPC3 protein in a test sample, comprising using two different antibodies binding to different epitopes present in the N-terminal region of GPC3 protein.

Method for assaying soluble GPC3 protein

A method for separating a vesicle having a lipid bilayer membrane from a biological sample, includes forming a complex of a vesicle and a solid phase carrier by bringing the biological sample containing the vesicle having the lipid bilayer membrane into contact with the solid phase carrier to which a ligand for recognizing a surface antigen present on a surface of the vesicle is bound. The complex is washed. The forming is performed in the presence of a nonionic surfactant which does not comprise an aromatic group to reduce an aggregation of the complex.
