  • Staining kit for proteins and nucleic acids
    Patent number: 5279792
    Abstract: A kit for staining proteins and nucleic acids wherein the stain is a suspension of colloidal metal particles and the proteins and nucleic acids are visualized as a colored signal localized at the binding site of the colloidal metal particles to the proteins or nucleic acids or quantitatively determined at this site following art-known spectrophotometric procedures.
    Type: Grant
    Filed: June 3, 1991
    Date of Patent: January 18, 1994
    Assignee: Janssen Pharmaceutica N.V.
    Inventors: Marc K. J. J. Moeremans, Guido F. T. Daneels, Marc C. De Raeymaeker, Jan R. De Mey
  • Staining method for proteins and nucleic acids
    Patent number: 4920059
    Abstract: A process for staining proteins and nucleic acids wherein the stain is a suspension of colloidal metal particles and the proteins and nucleic acids are visualized as a colored signal localized at the binding site of the colloidal metal particles to the proteins or nucleic acids or quantitatively determined at this site following art-known spectrophotometric procedures.
    Type: Grant
    Filed: June 12, 1985
    Date of Patent: April 24, 1990
    Assignee: Janssen Pharmaceutica N.V.
    Inventors: Marc K. J. J. Moeremans, Guido F. T. Daneels, Marc C. De Raeymaeker, Jan R. De Mey
  • Blot overlay assay using colloidal metal particles
    Patent number: 4775636
    Abstract: A method for detecting and/or determining an agglomerate formed by the reaction between a specific binding agent and the corresponding acceptor substance according to the general methodology of blot overlay assays by using colloidal metal particles labelled components which may be visualized as a coloured signal at the surface of the blotting medium characteristric for the colloidal metal particles used or quantitatively determined following art-known spectrophotometric procedures such as densitometry.
    Type: Grant
    Filed: October 27, 1987
    Date of Patent: October 4, 1988
    Assignee: Janssen Pharmaceutica N.V.
    Inventors: Marc K. J. Moeremans, Guido F. T. Daneels, Jan R. De Mey
  • Bright field light microscopic method of localizing tissue antigens
    Patent number: 4446238
    Abstract: The use of colloidal gold as a bright field light microscopic marker for the immunocytochemical localization of antigens in histological sections, namely the two step or the bridge immuno gold staining method.
    Type: Grant
    Filed: January 25, 1982
    Date of Patent: May 1, 1984
    Assignee: Janssen Pharmaceutica N.V.
