  • Solid phase immunoassay using immunoreagents immobilized on inert synthetic resin surfaces
    Patent number: 4778767
    Abstract: A solid phase immunoassay comprises the steps of(a) immobilizing an immunoreagent on the surface of a carrier comprised of an inert synthetic resin selected from the group consisting of polyimides and polyfluorinated synthetic resins,(b) contacting the immunoreagent with a complementary immunoreagent whereby an immunocomplex immobilized on said carrier is formed,(c) quantitating the immobilized immunocomplex.An element useful in conducting this solid phase immunoassay is prepared by a process of treating the surface of an article comprised of a synthetic polymer selected from the group consisting of polyimides and polyfluorinated synthetic resins to make it adsorptive of an immunoreagent which comprises the steps of(a) thoroughly rinsing the surface with a water-miscible organic solvent,(b) thoroughly rinsing the surface with water.
