  • Dry analytical elements for the determination of protein
    Patent number: 6046052
    Abstract: A dry analytical element is disclosed which can be used to sensitively and rapidly detect and quantitate protein. The assays are carried out using a dye that reacts with protein and molybdate ion to produce a measurable change in the spectral absorption of the dye. Also disclosed are polymers which stabilize and enhance the accuracy of the assay, and compounds which reduce interference by bicarbonate.
    Type: Grant

    Inventors: Thomas Arter, David B. LaTart, John C. Mauck, Richard C. Sutton, Wayne Weber, Robert Winterkorn, James Schaeffer
  • Electrophoresis element comprising a polymer containing a haloacetamido group
    Patent number: 5212253
    Abstract: Described are novel acrylic monomers, homopolymers and copolymers prepared therefrom, and electrophoresis gel media prepared by crosslinking certain copolymers of the invention by a crosslinking reaction that does not involve a free-radical vinyl addition mechanism.
    Type: Grant
    Filed: November 2, 1989
    Date of Patent: May 18, 1993
    Assignee: Eastman Kodak Company
    Inventors: Ignazio S. Ponticello, David B. LaTart
  • Polymeric electrophoresis media
    Patent number: 5149416
    Abstract: Preformed, water-soluble, acrylamide based copolymers comprising a minor proportion of a comonomer, which comonomer contains a site for a crosslinking reaction with a selected crosslinking agent by a reaction that does not involve a free-radical vinyl addition mechanism, which copolymers have M.sub.w and M.sub.n values within selected ranges, can be conveniently and safely used to prepare electrophoresis gel media in situ.
