  • Patent number: 8216581
    Abstract: The present invention relates to novel methods of identifying and producing an anti-platelet autoantibody. More preferably, the invention relates to identification and production of a human monoclonal anti-platelet autoantibody. Moreover, the invention relates to methods for treating or alleviating a disease, disorder or condition mediated by an anti-platelet autoantibody specifically binding with a platelet, or a component thereof, such as, but not limited to, idiopathic thrombocytopenic purpura, among others. Preferably, the antibody is an unglycosylated H44L4 Fab.

  • Patent number: 6979534
    Abstract: The invention relates to methods of agglutinating or capturing cells comprising providing a mixture comprising a population of cells and a population of bacteriophage expressing a first antibody on the surface of the bacteriophage, the first antibody being specific for an antigen-bearing moiety expressed by at least a portion of the cells in the cell population, wherein the first antibody binds to the portion of the cells causing the bacteriophage to also bind to the portion of the cells, adding to the mixture a second antibody specific for the bacteriophage, wherein binding of the second antibody to bacteriophage bound to the portion of the cells causes the portion of the cells to agglutinate or be captured.

  • Patent number: 5876925
    Abstract: The invention includes methods of isolating DNA and a protein encoded thereby, the protein being capable of binding to an antigen-bearing moiety. The methods comprise generating a DNA library expressing the protein in a virus vector. A magnetic label is added to cells expressing the antigen-bearing moiety and the cells are incubated with virus expressing the protein in the presence of an excess of unlabeled cells which do not express the antigen-bearing moiety to form a mixture, wherein the virus binds to the magnetically labeled cells. Cells having virus bound thereon are isolated from the mixture and DNA encoding the protein and the protein are obtained therefrom.
