  • Patent number: 7105638
    Abstract: Disclosed is a method for the isolation and purification of polypeptides expressed in host cells by recombinant DNA techniques. A fused polypeptide is produced containing a desired polypeptide fused to additional amino acids. The additional amino acids define a leader sequence having properties exploitable in purification, a hinge region, and a cleavage site. The hinge region is cysteine-free and has a secondary structure which serves to expose the cleavage site to a selected endopeptidase. The method of the invention involves the production of a fused polypeptide which may be efficiently isolated by exploiting the properties of the leader sequence, and then efficiently cleaved at the cleavage site in an appropriate aqueous environment by virtue of the influence of the hinge on the cleavage agent/cleavage site reaction and other properties of the fused polypeptide.

  • Publication number: 20060116507
    Abstract: A method and system for controlling the provisioning of a device with information for accessing services of a wireless service provider via a wireless network is provided. The provisioning system initially stores automatic provisioning information on the device that includes the identification of wireless service providers that have the capability to automatically provision the device. When a user of the device wants to subscribe to a service of a service provider, the provisioning system requests an automatic provisioning service of the service provider to provide information describing available services and information needed to subscribe to those services. When the user selects a service and provides the needed information, the provisioning system retrieves provisioning information for the selected service from the service provider. The provisioning system stores the provisioning information on the device so that the device can then be used to access the selected service of the service provider.

  • Patent number: 7041641
    Abstract: Disclosed herein are improved osteogenic devices and methods of use thereof for repair of bone and cartilage defects. The devices and methods promote accelerated formation of repair tissue with enhanced stability using less osteogenic protein than devices in the art. Defects susceptible to repair with the instant invention include, but are not limited to: critical size defects, non-critical size defects, non-union fractures, fractures, osteochondral defects, subchondral defects, and defects resulting from degenerative diseases such as osteochondritis dessicans.

  • Patent number: 6949505
    Abstract: Disclosed are methods and compositions for maintaining neural pathways in a mammal including: enhancing survival of neurons at risk of dying; inducing cellular repair of damaged neurons and neural pathways; stimulating neurons to maintain their differentiated phenotype; and promoting dendritic outgrowth, including maintaining dendritic arbors and regenerating dendritic architecture. In one embodiment, the invention provides means for stimulating CAM expression in neurons. The invention also provides means for evaluating the status of nerve tissue, including means for detecting and monitoring neuropathies in a mammal. The methods, devices and compositions include a morphogen or morphogen-stimulating agent provided to the mammal in a therapeutically effective concentration.

  • Patent number: 6936582
    Abstract: OP/BMP morphogen is combined with GDNF/NGF neurotrophic factors in promoting the survival or growth, or inhibiting the death or degeneration, of mammalian cells, particularly neural cells, which express OP/BMP-activated serine/threonine kinase receptors and GDNF/NGF-activated tyrosine kinase receptors. Also discosed are methods for the treatment of such cells, including treatments for mammals afflicted with, or at imminent risk of, damage or injury to, such cells, as well as new pharmaceutical preparations for such treatments.
