Since the 1970 's, Asahi Kasei has been producing and selling ultrafiltration (UF) and microfiltration (MF) membrane modules manufactured with its proprietary technology. As a recent achievement, Asahi Kasei has coupled graft polymerization technology to its proprietary technology and successfully developed a protein adsorption membrane module for refining antibody pharmaceuticals. The membrane of the module has graft chains produced on its micropore surface and an anion-exchange group is fixed to the graft chains to induce protein adsorption, which offers a high capability to adsorb protein even at high permeate flux. Furthermore, the elaborately designed structure of the module enables high scalability. This technical report introduces the design concept and characteristic performance of this protein adsorption membrane module newly developed.
