  • Patent number: 7932043
    Abstract: Methods of preparing monoclonal antibodies that differentially bind to a single conformer of a protein of interest are described. Passive immunization using these antibodies as well as use of conformer-specific antibodies as diagnostic reagents for the purpose of stratification of patient populations with regards to disease outcome, drug efficacy or drug sensitivity is also disclosed as well as active immunization with the protein conformer. In the screening techniques, detection can be for example by tissue immunostaining, western blotting or solution IP. A specific mab termed 7VC which shows conformation specificity to CtmPrP, a prion protein conformer that triggers neurodegeneration under specific assay conditions of pH and copper concentration, is described. A second specific antibody termed 19B10 shows conformation specificity for NtmPrP, a prion protein conformer that downregulates total PrP expression and effects cell differentiation.

  • Patent number: 7041462
    Abstract: Methods and compositions are provided for identifying novel conformers of proteins not known to exist as different conformers. By using chimeric genes replacing a native signal sequence with a different signal sequence resulting in the production of a conformer, one can compare the native protein with the product of the chimeric gene. Where the conformations are different, the different protein may be used for production of antibodies, elucidation of mechanisms associated with the native and different conformer protein, assays for the presence of the different conformer in physiological samples, identification of compounds specifically binding to the conformer, particularly drugs, etc. Where the formation of the conformer is associated with a diseased state, the conformer may be used in screens to identify compounds as drug candidates.
