Abstract
The present invention relates to composite materials useful for purifying proteins obtained from biological feedstocks. The composite materials of the invention comprise a porous support having an average pore size of 5 to 500 nm, said porous support being filled with a first polymer which is cross-linked, and a second polymer which is not crosslinked and is covalently bonded to the external surface of the cross-linked polymer-filled porous support.
