  • Patent number: 5668002
    Abstract: The human tumor-associated antigen CO-029 is a monoclonal antibody-defined, 27-34 kDa cell surface glycoprotein. A full-length cDNA clone for CO-029 is described. When transiently expressed in COS cells, the cDNA clone directs the synthesis of an antigen reactive with monoclonal antibody CO-029 in mixed hemadsorption and immunoblot assays. Sequence analysis reveals that CO-029 belongs to a family of cell surface antigens which includes the melanoma-associated antigen ME491, the leukocyte cell surface antigen CD37, and the Sm23 antigen of the parasitic helminth Schistosoma mansoni.

  • Patent number: 5296348
    Abstract: The present invention provides a method for selecting from among many monoclonal antibodies capable of binding to a surface antigen on a tumor cell, the antibody which also can internalize into the cell and exert an appropriate molecular effect on the level of gene regulation in the tumor cell. Such antibodies can most effectively be employed to damage the tumor cell.

  • Patent number: 4849509
    Abstract: The present invention is directed to monoclonal antibodies, and hybridomas which produce them, which are reactive with ganglioside antigens GD2 and GD3 and are essentially non-reactive with other ganglioside antigens. The invention further relates to methods of using these antibodies.

  • Patent number: 4786593
    Abstract: It has been determined that nerve growth factor binds to a cell surface protein of human neural crest origin having a molecular weight of about 75,000 daltons. New monoclonal antibodies specifically imunoprecipitate these receptor molecules, and also inhibit binding of the hormone to the receptor. These monoclonal antibodies show significantly higher reactivity with primary and metastatic melanoma cell lines than with melanocytes. The antibodies are used in a diagnostic method for histochemical detection of human neural crest disease.

  • Patent number: 4607009
    Abstract: An assay for determining the Lewis blood group of a patient consists of testing a body sample for the presence of Lewis.sup.a and Lewis.sup.b antigens.

Body samples which may be tested include: saliva, serum, urine, and paraffin-embedded tissue samples. Hybridoma cell lines and the antibody compositions they produce specific for these antigens are provided for use in the assay.

  • Patent number: 4028469
    Abstract: A bread containing substantial quantities of alfalfa provides a convenient, palatable form of introducing significant quantities of alfalfa into the human diet. The bread, which preferably contains honey, retains bread-like texture, taste and odor despite the presence of substantial quantities of alfalfa.
