  • High concentration white blood cells as a therapeutic product
    Patent number: 7169547
    Abstract: A therapeutic product formed from a high concentration of white blood cells having a high degree of cell viability. The white blood cells are sequestered from their normal population presence in whole blood by placing the blood into a container and preventing coagulation of the blood, separating the blood into two components, one of which is extremely rich in white blood cells through the use of a reagent and centrifugation, sequestering the white cell concentration, and freezing the white cells.
    Type: Grant
    Filed: May 15, 2001
    Date of Patent: January 30, 2007
    Assignee: New York Blood Center, Inc.
    Inventors: Pablo Rubinstein, Philip Henry Coelho, Cladd E. Stevens
