  • Publication number: 20120219968
    Abstract: The present invention provides expression vectors that facilitate high levels of expression of GPCR proteins. Encompassed by the invention are methods and compositions for recombinant cell lines expressing GPCR proteins with the aid of the expression vectors of the instant invention. The recombinant cell lines of the instant invention express GPCR proteins at levels of at least about 150,000 copies of the protein per cell. The present invention also provides methods and compositions for raising antibodies against GPCR proteins using the high expressing recombinant cells of the instant invention.

  • Patent number: 7517952
    Abstract: Compositions and methods for the therapy and diagnosis of cancer, such as prostate cancer, are disclosed. Compositions may comprise one or more prostate-specific proteins, immunogenic portions thereof, or polynucleotides that encode such portions. Alternatively, a therapeutic composition may comprise an antigen presenting cell that expresses a prostate-specific protein, or a T cell that is specific for cells expressing such a protein. Such compositions may be used, for example, for the prevention and treatment of diseases such as prostate cancer. Diagnostic methods based on detecting a prostate-specific protein, or mRNA encoding such a protein, in a sample are also provided.
