Patents by Inventor Ethel R. Macrea

Ethel R. Macrea 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).

  • Automated molecular pathology apparatus having independent slide heaters
    Patent number: 7396508
    Abstract: Apparatus and methods for automatically staining or treating multiple tissue samples mounted on microscope slides are provided. Individualized slide temperature control is accomplished by the heating system according to the present invention that has thermal platforms radially mounted to the carousel for heating the slides and sensing the temperature of each. The heating system also permits automated de-waxing if necessary.
    Type: Grant
    Filed: July 12, 2000
    Date of Patent: July 8, 2008
    Assignee: Ventana Medical Systems, Inc.
    Inventors: William Richards, Charles D. Lemme, Kimberly Christensen, Ethel R. Macrea
  • Removal of embedding media from biological samples and cell conditioning on automated staining instruments
    Patent number: 6855559
    Abstract: The present invention provides reagents for use in an automated environment for removing or etching embedding media by exposing a biological sample to be stained in histochemical or cytochemical procedures without the dependence on organic solvents. The reagents comprise components optimized to facilitate removal or etching of the embedding media from the biological sample. The present invention also provides reagents for use in an automated environment for cell conditioning biological samples wherein the cells are predisposed for access by reagent molecules for histochemical and cytochemical staining procedures. The reagents comprise components optimized to facilitate molecular access to cells and cell constituents within the biological sample.
