Abstract: A method of purifying biomolecules with an anion exchanger containing a membrane having a surface having a polymer such as a primary or secondary amine ligand formed thereon, such as polyallylamine. The feedstock is introduced to the exchanger in the presence of one or more ionic-modifiers by themselves or in combination with monovalent salt. The ionic modifier alters the binding ability of the primary amines such that they retain a significant binding capacity for highly charged species such as DNA but lose part or almost all of their binding capacity for less charged species such as viruses or proteins at pH above the pI of the virus or protein.
