  • Magnetic immunodiagnostic methods and kit for the demonstration of antibody/antigen complexes in erythrocyte blood grouping and phenotyping
    Patent number: 9618518
    Abstract: The current invention relates to a magnetic immunodiagnostic method for the demonstration of antibody/antigen complexes of blood group and phenotype. Such a method involves the research and/or identification of antibodies or antigens, preferably anti-antigen antibodies or antigens of a blood group. This method implements a suspension of magnetic particles coated with an antibody anti-glycophorin A that can recognize and specifically magnetize erythrocytes. The invention also includes a device and kit for carrying out one such method.
    Type: Grant

    Date of Patent: April 11, 2017
    Assignee: DIAGAST
    Inventors: Laurence Fauconnier, Yves Barbreau, Arnaud Boulet, Maha Zakhour
  • Use of ferrofluids for phenotyping blood and related applications
    Patent number: 8889368
    Abstract: The invention relates to a method for phenotyping blood and/or performing an irregular agglutinin test and/or for determination of compatibility of a donor and receiver, using an aqueous solution of ferrofluid, obtained from a mixture of polyoxoanions of Fe(III) and at least one metal M(II) of oxidation state II. The invention further relates to a kit for carrying out said procedure.
