A new ion-exchange medium was prepared from magnetic particles of ∼1.0 µm through coating with small zwitterions and then functionalizing with ampholytic groups for the isoelectric point of ∼6.4 and denoted MSP-ZEWB. With Meyerozyma guilliermondii uricase (MGU) as the model of soluble proteins, the purification of a protein via ion-exchange was compared between MSP-ZEWB through elution in discontinuous mode and Toyopearl SP-650C as a classical ion-exchange medium through elution in continuous mode. MGU was adsorbed at pH 7.6 or 8.0 and e
