  • Methods of Manufacturing a Biologic Using a Stable Storage Intermediate
    Publication number: 20100310548
    Abstract: The present invention is directed to methods of isolating and purifying protein from a bioreactor process. The invention relates to employing a protein phase separation methodology to isolate or purify protein product in the forms of solid, semi-solid, or suspension during a protein manufacturing purification process as a stable storage intermediate. This approach is designed to allow the isolated protein product (purified or partially purified) to be stored over an extended period of time prior to further protein purification steps.

  • Method of treating cancer by administering conjugates comprising human IL-18 and substitution mutants thereof
    Patent number: 7736639
    Abstract: Methods of treating cancer in patients in need thereof with human interleukin-18 (IL-18) polypeptides and substitution mutants thereof that are conjugated to water-soluble polymers at specific sites on the human IL-18 protein are disclosed.
    Type: Grant
    Filed: December 21, 2007
    Date of Patent: June 15, 2010
    Assignee: GlaxoSmithKline LLC

  • METHOD OF TREATING CANCER BY ADMINISTERING CONJUGATES COMPRISING HUMAN IL-18 AND SUBSTITUTION MUTANTS THEREOF
    Publication number: 20080206189
    Abstract: Human interleukin-18 (IL-18) polypeptides and substitution mutants thereof were conjugated to water-soluble polymers at specific sites on the human IL-18 protein. These conjugated human IL-18 and substitution mutants thereof retain biological activity. These conjugated cytokines demonstrate enhanced and unexpected biological properties when compared to the corresponding unconjugated cytokines.

  • Crash helmet that is assembled easily and rapidly
    Publication number: 20060230507
    Abstract: A crash helmet includes a helmet body, a face mask, and a binding device for attaching the face mask to the helmet body. Thus, the face mask is mounted on and removed from the helmet body easily and rapidly by operation of the binding device, so that the crash helmet is assembled and disassembled easily and rapidly, thereby facilitating a user mounting and dismantling the crash helmet. In addition, the face mask is mounted on the helmet body by the binding device without needing a metallic spring to prevent the crash helmet from being inoperative during a long-term utilization, thereby enhancing the lifetime of the crash helmet.
