Abstract:
To provide a separating agent for IgG purification, whereby IgG can be separated and purified efficiently at a high purity, and a method for purifying an IgG using it.A separating agent for IgG purification, characterized in that a polyacrylic acid and/or a polymethacrylic acid is immobilized on a carrier, and a method for purifying an IgG monomer, characterized in that a mixture containing an IgG monomer and an impurity containing polymeric IgG is contacted to the separating agent and eluted.
