    Abstract: This invention relates generally to modified porous solid chromatographic media and processes for the preparation and use of same. In particular, chromatographic media of porous mineral oxide, polymeric, or polymer-coated mineral oxide supports are disclosed which are characterized by a reversible high sorptive capacity and high intraparticle mass transfer rates. In order to prevent non-specific adsorption of or interaction with biomolecules, these supports may be passivated by use of a passivation mixture comprising a main monomer, a passivating monomer, and a crosslinking agent, which mixture upon polymerization results in substantial elimination of the undesirable non-specific interaction with biomolecules.

    Abstract: Dried agarose or gelose-containing films which are rehydratable into aqueous gel films are disclosed. The dried films are prepared by first forming, on a support, an aqueous gel film containing at most 5% by weight of agarose or gelose and a water-soluble linear polymer or copolymer of acrylamide or methacrylamide. The viscosity of such polymer and copolymer in a 5% aqueous solution at 22.degree. C is about 17000 centipoises or less and preferably about 6000 centipoises or less. The aqueous gel film is then dried according to known techniques, with the linear polymer or copolymer of acrylamide or methacrylamide being included in the dried film.
