  • Publication number: 20120225807
    Abstract: Improved bacterial secretion signals derived from pelB and ompA are provided. The improved variants enhance bacterial membrane secretion are thus useful for production of proteins secreted from bacteria including proteins displayed on filamentous phage particles, and, in particular, proteins requiring oxidative formation of covalent bonds, such as disulfide bonds within or between polypeptide chains in order to form a correctly folded and functional protein structure. Described herein are methods for the multivalent display of complex dimeric proteins on the surface of a bacteriophage particle and combinatorial synthetic libraries of such proteins displayed as a fusion polypeptide with filamentous phage pIX coat protein. Heterodimeric or more complex interchain bonded structures may also be displayed using the method of the invention.

  • Publication number: 20120225085
    Abstract: Methods are provided for the display of a complex homodimer protein on the surface of a bacteriophage particle and combinatorial synthetic libraries of such proteins displayed as a fusion polypeptide with filamentous phage pIX coat protein. Heterodimeric or more complex interchain bonded structure, such as disulfide-linked, multimeric proteins, may be displayed using the method of the invention.

  • Publication number: 20120021001
    Abstract: The present invention is directed to a bovine viral diarrhea virus comprising at least one helicase domain amino acid mutation wherein the mutation in the NS3 domain results in a loss of recognition by a monoclonal antibody raised against wild-type NS3 but wherein viral RNA replication and the generation of infectious virus is retained. The present invention is useful, for example, to produce a marked bovine viral diarrhea virus vaccine or to differentiate between vaccinated and infected or unvaccinated animals.
