A method of reducing aggregate and product-contaminant complex content in a protein preparation including a desired protein includes (i) contacting the protein preparation with at least one solid surface comprising at least one surface-bound ligand capable of binding a metal, the surface-bound ligand being capable of binding a metal is initially substantially devoid of a metal, the operating conditions are selected to substantially prevent the binding of the desired protein to the at least one solid surface and (ii) separating the protein preparation from the surface-bound ligand, such that when more than one surface- bound ligand is present, each surface-bound ligand is independently either of the same net charge or charge neutral.
