The HPLC results showing ultraviolet profiles of MAG3-Cet, MAG3-Cet-F(ab)2 and MAG3-Cet-Fc. (a) The HPLC result of MAG3-Cet. (b) The HPLC result of MAG3-Cet-F(ab)2 and MAG3-Cet-Fc after digesting MAG3-Cet with IdeS protease. (c) The HPLC result of the mixture from (b) but after reaction with protein A beads. The residual MAG3-Cet and most of the MAG3-Cet-Fc were removed by protein A beads. (d) The HPLC result of the mixture of (a) and (c).
