  • Publication number: 20060127956
    Abstract: A method and device is described for a quality control device for immunohistochemical testing of surgical biopsies. Immunohistochemistry testing involves the use of antibodies to detect the presence of proteins that have diagnostic or prognostic importance. In this invention, peptides are covalently attached to glass microscope slides. The peptides represent antibody contact sites to the native protein. Namely, the peptide contains the same amino acid sequence as the epitope in the native protein to where the antibody binds. Alternatively, peptides may not necessarily share the exact sequence as found in the native protein but they still bind to the antibody. To use this invention, tissue sections derived from surgical biopsies may be mounted on glass slides bearing the peptides. As the immunohistochemical stain is performed on the tissue section, a similar reaction sequence occurs at the site of the glass slide where the peptide is located.

  • Patent number: 7011940
    Abstract: The invention describes quality control devices for assays that measure analytes in cells and tissue samples, and methods of use thereof. In particular, the quality control device comprises a matrix affixed with synthetic controls in different concentrations, or different synthetic controls. The quality control device can be adhered to a microscope slide via an adhesive or chemically attached to a microscope slide and processed simultaneously with a tissue sample.

  • Patent number: 6855490
    Abstract: The invention describes a method for attaching biological molecules, such as proteins, nucleic acids, and carbohydrates to a glass surface. In particular, a covalent attachment method is described wherein a glass surface is first activated with a water-stable form of an isocyanate, termed a protected isocyanate. The protecting group of the isocyanate moiety is displaced by amines, hydroxyl, or carboxyl groups of biological molecules, leading to covalent attachment to the glass surface.
