Abstract
Described are ion-exchange membranes that include a porous polymeric membrane and imidazole ion-exchange groups at surfaces of the membrane; ion-exchange membranes and filters that contain the ion-exchange membranes; and methods of using the ion-exchange membranes and filters for separating charged biological molecule from a liquid.
Claims5
A method of separating a charged biological molecule from a liquid using a porous ion-exchange membrane sheet, the method comprising contacting liquid that contains the charged biological molecule with a porous ion-exchange membrane comprising a porous polymeric sheet and imidazole ion-exchange groups at surfaces of the porous polymeric sheet, at an adsorption condition that causes the charged biological molecule to adsorb onto the ion-exchange membrane.
