  • Patent number: 11833279
    Abstract: A method includes: depositing whole blood into at least one separator tube; subjecting the at least one separator tube to a first centrifugal force to cause a combination of the first centrifugal force and separator gel within each separator tube of the at least one separator tube to separate plasma of the whole blood from red and white blood cells of the whole blood within the at least one separator tube, wherein the plasma includes ?2M molecules; transferring one or more portions of the plasma from within the at least one separator tube and into at least one isolator; and subjecting the at least one isolator to a second centrifugal force to cause a combination of the second centrifugal force and a filter within each isolator of the at least one isolator to isolate the ?2M molecules from other components of the plasma within the at least one isolator.
    Type: Grant
