Abstract:
An object of the present invention is to provide a separation agent for separating a human serum-derived IgG polyclonal antibody. This object is achieved by a separation agent for separating a human serum-derived IgG polyclonal antibody, the separation agent including: a carrier; and a single-chain antibody which has a dissociation constant for a human serum-derived IgG polyclonal antibody of not more than 3.0×10−8 M and which binds to the surface of the carrier via a chemical bond.
