Abstract
This invention relates generally to modified porous solid supports and processes for the preparation and use of same. In particular, passivated porous mineral oxide supports are disclosed which are characterized by a reversible high sorptive capacity substantially unaccompanied by non-specific adsorption of or interaction with biomolecules. Passivation is achieved by use of a passivation mixture comprising a main monomer, a passivating monomer and a crosslinking agent, which mixture upon polymerization results in the substantial elimination of the undesirable non-specific interaction with biomolecules.
