Abstract

Disclosed are ionic gel-coated beads (including Hydrogel™-coated beads), which are capable of adsorbing, or absorbing, proteins and other biomolecules onto or into the gel coating. The gel-coated beads with absorbed or adsorbed biomolecules are suitable for use in an assays, purification or other purposes. The beads have a core made from any of a number of materials, including latex, coated with the gel shell. The biomolecules can be retained within the gel, following adsorption, by covalent attachment, or, by selection of conditions of ambient pH and/or ionic strength such that they are retained without further reaction. Therefore, adsorbed proteins would retain the ability to bind to their respective ligands.
