Patents by Inventor Eleanor Canova-Davis

Eleanor Canova-Davis has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Homogeneous enzyme immunoassay system and method
    Patent number: 4783400
    Abstract: A liposome assay reagent for determination of an analyte in a homogeneous immunoassay. The reagent includes a suspension of oligolamellar lipid vesicles containing encapsulated glucose-6-phosphate dehydrogenase (G6PD), at a specific activity of between about 1-15 units/.mu.mole vesicle lipid, and glucose-6-phosphate (G6P) at a concentration of at least about 5 mM. The encapsulated G6P protects the enzyme against inactivation on preparation, by reverse phase evaporation in the presence of organic solvent, and on storage as an aqueous suspension.
    Type: Grant
    Filed: August 20, 1986
    Date of Patent: November 8, 1988
    Assignee: Cooper Lipotech
    Inventors: Eleanor Canova-Davis, Viola T. Kung, Carl T. Redemann
  • Liposome immunoassay reagent and method
    Patent number: 4622294
    Abstract: A liposome assay reagent for determination of an analyte in a homogeneous immunoassay. The reagent includes a suspension of oligolamellar lipid vesicles containing encapsulated glucose-6-phosphate dehydrogenase (G6PD), at a specific activity of between about 1-10 units/.mu.mole vesicle lipid, and glucose-6-phosphate (G6P) at a concentration of at least about 5 mM. The encapsulated G6P protects the enzyme against inactivation on preparation, by reverse phase evaporation in the presence of organic solvent, and on storage as an aqueous suspension.
