  • Publication number: 20030143224
    Abstract: The present invention provides antibodies that specifically bind with a high degree of binding affinity to a native ungulate PrPC and/or a denatured ungulate PrPSc, but not to a native ungulate PrPSc. Preferred antibodies find native bovine PrPC and treated PrPSc but not native bovine PrPSc and can be used in an assay to determine if a sample is infected with infectious prions, i.e. PrPSc.

  • Patent number: 6562341
    Abstract: Antibodies are disclosed which specifically bind to native PrPSc in situ. Preferred antibodies bind only to the native PrPSc of a particular species e.g., human, cow, sheep, pig, etc. Particularly preferred antibodies bind specifically to a particular isoform of human PrPSc. Preferred antibodies of the invention are (1) produced by phage display methodology, (2) bind specifically to native PrPSc, (3) neutralizes the infectivity of prions, (4) bind to PrPSc in situ and (5) bind 50% or more of PrPSc in a liquid flowable sample. Antibodies of the invention can be bound to a substrate and used to assay a sample (which has any PrPc denatured via proteinase K) for the presence of PrPSc of a specific species which PrPSc is associated with disease. Antibodies which specifically bind to human PrPSc can be labeled and injected carrying out an in vivo diagnostic test to determine if the human is infected with prions associated with disease.

  • Publication number: 20020168629
    Abstract: The present invention provides a novel method for the identification and clonal isolation of antibodies that bind to unique epitopes. The method is based on the use of antibodies as solid phase capture reagents to bind a known capture antibody epitope, thereby precluding the capture antibody epitope from being presented to a population of antibodies to be screened. The method is particularly suited for screening libraries of cloned antibodies, such as phage display combinatorial antibodies. An antibody specific for herpes simplex virus (HSV), was employed as a model for the assay.

  • Publication number: 20020146753
    Abstract: It has been discovered that one of the causes of human rheumatoid arthritis is an autoimmune reaction to human glucose-6-phosphate isomerase. While human glucose-6-phosphate isomerase is a normal constituent of living tissue, and the underlying reasons for the autoimmune reaction are not understood, this discovery enables effective treatment of the disease, especially when the human immune reaction is the primary cause of the rheumatoid arthritis. The human antibody, anti-glucose-6-phosphate isomerase IgG, can be used to develop immunopolypeptides having binding capacity with the antigen. Antibodies and antibody fragments to the antiglucose-6-phosphate isomerase IgG, antisense oligonucleotides, conjugates of human GPI with cytotoxic agents, immobilized human GPI may be used to ameliorate or eliminate the immune reaction. The peptide, nucleotide products as well as methods of diagnosis and treatment are provided.

  • Patent number: 6395275
    Abstract: The present invention describes synthetic human monoclonal antibodies that immunoreact with and neutralize human immunodeficiency virus (HIV).

  • Publication number: 20020055133
    Abstract: The invention provides peptide synthons having protected functional groups for attachment of desired moieties (e.g. functional molecules or probes). Also provided are peptide conjugates prepared from such synthons, and synthon and conjugate preparation methods including procedures for identifying the optimum probe attachment site. Biosensors are provided having environmentally sensitive dyes that can locate specific biomolecules within living cells and detect chemical and physiological changes in those biomolecules as the living cell is moving, metabolizing and reacting to its environment. Methods are included for detecting GTP activation of a Rho GTPase protein using polypeptide biosensors. When the biosensor binds GTP-activated Rho GTPase protein, the environmentally sensitive dye emits a signal of a different lifetime, intensity or wavelength than when not bound.
