Summary for Patent: 4,829,098
Title: Immobilized biomolecules and method of making same
Abstract:A method of biomolecule immobilization is described in which the biomolecule itself or, alternatively, a monomer-conjugated biomolecule, is grafted with free monomer onto a hydrophilic, solid-phase, polymeric substrate which has been pre-irradiated with ionizing radiation. The pre-irradiation step is carried out, preferably at C. in air, while the grafting step is carried out at C. in a substantially oxygen-free atmosphere. The technique is applicable to immobilization of a wide variety of biomolecules, such as enzymes, catalysts, hormones, lectins, drugs, vitamins, antibodies, antigens, nucleic acids, DNA and RNA segments, pesticides, dyes and fertilizers. The products may be used for therapeutic or diagnostic applications or bioseparations.
