摘要：
A monoclonal antibody or an antibody fragment thereof is provided, in which the monoclonal antibody or the antibody fragment thereof specifically binds to a sugar chain in which a terminal sialic acid residue is bonded to galactose by an α2,3 bond, and is not dissociated from the sugar chain after the binding to the sugar chain in which the terminal sialic acid residue is bonded to the galactose by the α2,3 bond.α2,3
