  • Homologous recombination in plants
    Patent number: 6781032
    Abstract: The present invention provides novel methods for modifying target nucleotide sequences in a plant cell through the use of homologous recombination. The plant cell is transformed with a DNA construct comprising a polynucleotide sequence encoding a fusion polypeptide comprising a polypeptide sequence of interest linked to a reporter sequence.
    Type: Grant

    Date of Patent: August 24, 2004
    Assignee: The Regents of the University of California
    Inventors: Wilhelm Gruissem, John Jelesko, Masaki Furuya
  • Methods and compositions for independent DNA replication in eukaryotic cells
    Publication number: 20020086428
    Abstract: The invention provides methods and compositions for replicating a polynucleotide sequence independent of replication of chromosomal DNA in a cell.
    Type: Application

  • Receptors for immune complexes
    Patent number: 6326159
    Abstract: Receptors are disclosed that are antibodies that exhibit a binding affinity for an immune complex of a monoepitopic antigen and an antibody for such antigen that is substantially greater than the binding affinity for the monoepitopic antigen or the antibody for the monoepitopic antigen apart from the immune complex. Normally, the monoepitopic antigen has a molecular weight less than 1500 and is an organic compound. The antibodies of the present invention find use in a method for determining a monoepitopic antigen in a sample suspected of containing such antigen. The method comprises forming an immune sandwich complex comprising the monoepitopic antigen or an analog thereof, a first monoclonal antibody that binds to the monoepitopic antigen, and a second monoclonal antibody that is an antibody of the present invention and detecting the immune sandwich complex.

  • Receptors for immune complexes
    Patent number: 5223441
    Abstract: Receptors are disclosed that are antibodies that exhibit a binding affinity for an immune complex of a monoepitopic antigen and an antibody for such antigen that is substantially greater than the binding affinity for the monoepitopic antigen or the antibody for the monoepitopic antigen apart from the immune complex. In one embodiment the receptors are antibodies prepared against an affinity-labeled complex of an antigen and an antibody for the antigen. Normally, the monoepitopic antigen has a molecular weight less than 1500 and is an organic compound. The antibodies of the present invention find use in a method for determining a monoepitopic antigen in a sample suspected of containing such antigen. The method comprises forming an immune sandwich complex comprising the monoepitopic antigen or an analog thereof, a first monoclonal antibody that binds to the monoepitopic antigen, and a second monoclonal antibody that is an antibody of the present invention and detecting the immune sandwich complex.
