  • Patent number: 5756717
    Abstract: Disclosed are specifically designed binding, "protein imaged" sorbents which reversibly bind with high specificity and affinity a preselected macromolecule, specifically a protein. The sorbents define one or more cavities which have a binding surface complementary in shape to the molecular surface of the macromolecule and a plurality of positively and negatively charged chemical moieties spatially distributed in a mirror image and charge inverse of a subset of the ionizable groups on the molecular surface of the macromolecule. Also disclosed are methods of producing such sorbents, useful over a range of conditions, for both preparative and analytical chromatographic separations or for use in various types of analyses.
