  • Patent number: 9556413
    Abstract: The invention described below relates to an enclosed cell sorting device and methods of using the device. The device is constructed so that the entire process of cell sorting can be conducted under fully anaerobic conditions to retain viability of anaerobic cells before, during, and after cell sorting. This is accomplished by creating an anaerobic atmosphere for the high speed cell sorter and all its components and by the use of airlocks that allow the introduction of anaerobic containers into the chamber containing the sample.

  • Patent number: 9518117
    Abstract: Provided are monoclonal antibodies and antigen-binding fragments thereof that bind to, and inhibit the activity of, CD47, as well as monoclonal antibodies and antigen binding fragments thereof that compete with the former for binding to CD47. Also provided are combinations of any of the foregoing. Such antibody compounds are variously effective in 1) treating tissue ischemia and ischemia-reperfusion injury (IRI) in the setting of organ preservation and transplantation, pulmonary hypertension, sickle cell disease, myocardial infarction, stroke, and other instances of surgery and/or trauma in which IRI is a component of pathogenesis; 2) in treating autoimmune and inflammatory diseases; and 3) as anti-cancer agents that are toxic to susceptible cancer cells, promoting their phagocytic uptake and clearance, or directly killing such cells.
