Dana B. Jacobs 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).

  • Hematology controls for reticulocytes and nucleated red blood cells
    Patent number: 7195919
    Abstract: The present invention is drawn to a hematology control made from particles a particle having a biopolymer attached to a surface of the particle. The particle simulates a component of a blood sample, such as a reticulocyte or nucleated red blood cell component of a blood cell sample in a flow cytometer or hematology analysis instrument. The present invention is further drawn to methods of making and using the hematology control.
    Type: Grant
    Filed: December 19, 2003
    Date of Patent: March 27, 2007
    Assignee: Beckman Coulter, Inc.
    Inventors: Dana B. Jacobs, Paul W. Price, Nery Ortiz, Theodore J. Gerula
  • Hematology control product with increased closed vial stability
    Patent number: 6569682
    Abstract: An improved blood suspension media for hematological compositions, having particular utility with a red blood cell component for devices using electronic and optical means for blood determinations, and processes for using the suspension media. The suspension media finds particular utility in providing the hematology control product with a stable and consistent MCV and RDW for an extended product shelf life.

  • Stable hematology control composition and method of use
    Patent number: 5994139
    Abstract: The present invention relates to a hematology control product for automated hematology instruments containing an aqueous solution of at least one blood cell analog, an absorbance agent in an amount sufficient to simulate a hemoglobin concentration, and a stabilizing agent in an amount sufficient to stabilize the size of the blood cell analog when the control product is subjected to temperature ranging from -15.degree. C. to 45.degree. C. The control product does not require controlled temperature storage for product stability. In addition, a novel method of using a hematology control product is provided wherein the control product contains a single blood cell analog and is used to simulate both red blood cells and white blood cells on an automated hematology instrument.
