Abstract

A process for production of a microporous affinity membrane having regioselective affinity for compounds in blood or other biologically active fluids to be removed during purification of blood or said fluids is disclosed, as well as a microporous affinity membrane produced by said process, an adsorption device containing such a microporous affinity membrane, and use of such a microporous affinity membrane.
