Abstract: Microcellular polyethylene foam films offer a large internal surface of 20 m2/g.Through irradiation induced grafting process,it could connected some of hydroxyl and amine groups to form basic membranes,and then grafted with vinyl dimethyl azlactone to form modified microporous polyethylene membranes.It would absorb amine group of protein-Awith coordinate bonding in neutral solution and releasing in acid solution.We could used various modified membranes to carry out coordinate binding for isolation and purification of protein.

Key words: Microporous PE foam membranes, Grafting modified, Isolation of protein, New Filter
