Abstract: Antibodies directed against idiotypes on naturally occurring human anti-animal antibodies are disclosed for use in inhibiting xenograft rejection in human patients. An effective quantity of these anti-idiotypic antibodies is injected into the actual or potential xenograft recipient in order to bind to the idiotypes expressed on anti-animal antibodies as well as subpopulations of B lymphocytes, to inhibit hyperacute rejection of transplanted animal tissues or organs by the human patient. Alternatively, anti-idiotypic antibodies are used in the form of immunoaffinity columns to deplete anti-animal antibodies from the recipient's serum. Methods of making mouse monoclonal, mouse recombinant, and human recombinant anti-idiotypic antibodies are described, as well as immunoaffinity columns containing immobilized anti-idiotypic antibodies.

Abstract: The invention comprises an anti-idiotypic antibody designated 2F10 and permitted variants thereof, which have antigenic properties similar to the group specific "a" determinant of human hepatitis B surface antigen HBsAg and have at least partial but not complete homology with such surface antigen. The invention further comprises a peptide having a chain comprising the amino acid residues Ala Val Tyr Tyr Cys Thr Arg Gly Tyr His Gly Ser Ser Leu Tyr and permited variants thereof, which, like 2F10, have antigenic properties similar to the group specific "a" determinant of human hepatitis B surface antigen HBsAg and have at least partial, but not complete, homology with said surface antigen. The amino acid sequence is found in and forms a part of 2F10.

Abstract: The present invention provides a low cost, less toxic, anti-cancer immunotherapy which enhances the host's immune system ability to destroy or contain cancers, and also provides a diagnostic test for cancer. Specifically, the present invention provides monoclonal antibodies specific for, that is, specifically bind, oncofetal protein (OFP), a cancer cell product. Tumors treated with a single dose of the monoclonal antibodies against OFP are markedly reduced in size, and leukemic populations of cells treated with a single does of monoclonal antibodies against OFP are significantly decreased in number. Since the monoclonal antibodies of the present invention do not bind to tumor cells, the monoclonal antibody treatment overcomes the disadvantages associated with tumor cell targeting. Monoclonal antibodies to OFP offer a simple and inexpensive agent for use as a primary or adjuvant therapy against a wide variety of cancers and tumors in humans and other animals.

Abstract: Compositions containing a high concentration of the full repertoire of immunoglobulins, including IgA, IgM and IgG, are used to combat infections from microorganisms and viruses at a wound, surgical, or burn site, or normal tissue at times of risk of infection. The compositions can contain elevated antibody titers for several specific pathogens including S. aureus, CNS, Enterococci, S. epidermidis, P. aeruginosa, E. coli, and Enterobacter spp., etc. The compositions are applied directly to a wound or burn site as an ointment, creme, fluid, spray, or the like, prior to viral or bacterial attachment or biofilm formation such that adhesion of the pathogens is inhibited and the pathogens closest to the wound or burn site will be pre-opsonized for phagocytic killing prior to toxin release.
