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: Cell lines have been produced that secrete human monoclonal antibodies capable of binding to the lipopolysaccharide molecules of selected Pseudomonas aeruginosa IATS serotypes. Pharmaceutical compositions containing these antibodies, which can be in combination with other monoclonal antibodies, blood plasma fractions and antimicrobial agents, and the prophylactic and therapeutic use of such compositions in the management of infections are included. Prior to filing of this patent application the continuous transformed human cell lines 1C1, 6D6 and 8H7 described herein were deposited in the American Type Culture Collection and given the designations CRL 8941, 9171, and 9258, respectively.

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: A genus specific chlamydia oral or injectable vaccine is provided which comprises an anti-idiotype antibody capable of producing in an animal an anti-idiotypic antibody or Fab fragment thereof enclosed in microspheres formed of a pharmacologically acceptable polymer is capable of producing in an animal an anti-anti-idiotypic immune response (serum antibody, secretory antibody or T-cell responsee) which recognizes a glycolipid exoantigen (GLXA) of chlamydia. The oral or injectable vaccine is produced from an idiotypic antibody to GLXA which, in turn, is utilized to produce the anti-idiotypic antibody.

Abstract: The metastasis of cells, which express a glycoprotein of human carcinoembryonic antigen on the cells surfaces, is inhibited in a living organ by administering, in advance, to a subject, a monoclonal antibody which binds a peptide which comprises at least the peptide sequence of domain N in the glycoprotein of human carcinoembryonic antigen.

Abstract: A product and method of treating failure of passive immunity transfer and for stimulating growth and milk production in cows by administration of proteins purified from bovine colostrum is disclosed. Injecting, either subcutaneously or intravenously, prepared bovine colostrum containing immunoglobulins and nonspecific proteins increases immunoglobulins in the blood stream to effect passive transfer after gut closure. Also administration in spray dried form as a diet supplement to growing calves or adult cows improves growth and milk production due to the presence of previously unappreciated nonspecific proteins.

Abstract: The present invention relates to a method for the selective preparation of hybridoma cell lines which produce a murine monoclonal antibody (MAK) of the IgGl class with a high capacity for including NK cell-relate cytotoxicity against human CD16 antigen by co-culturing the hybridoma cells in the selection medium with unstimulated human NK (natural killer) cells. The invention furthermore relates to a cell line A9 of the DSM deposit number ACC 2148 obtainable in this manner, and a MAK obtainable thereform, and a method for the preparation of bispecific MAK's by the fusion of an anti-CD30 cell line HRS-3 with hybridoma cell lines, which is obtained by the above-mentioned selection process, expecially with the A9 line of DSM deposit number ACC 2148 obtaining especially the bispecific MAK of the HRS-3/A9 cell line with the DSM deposit number ACC 2142. These bispecific MAK's are suitable for the treatment and for the shrinking of established human tumors, especially human Hodgkin's tumors.

Abstract: The present invention provides three unique monoclonal antibodies directed against a portion of the Wilms' tumor antigen, and methods of use therefor in detecting, monitoring and diagnosing malignancies characterized by over-expression or inappropriate expression of the WT 1 protein.

Abstract: Cell lines have been produced that secrete human monclonal antibodies capable of binding to the lipopolysaccharide molecules of selected Pseudomonas aeruginosa IATS serotypes. Pharmaceutical compositions containing these antibodies, which can be in combination with other monoclonal antibodies, blood plasma fractions and antimicrobial agents, and the prophylactic and therapeutic use of such compositions in the management of infections are included.

Abstract: Murine monoclonal antibodies are prepared and characterized which bind selectively to high molecular weight mucins by immunoprecipitation test and are IgGs or IgMs. Immunotoxins comprising the monoclonal antibody and cytotoxic moiety were produced.

Abstract: Three unique monoclonal antibodies, each having an epitope located in amino acids 1-181 of the WT1 tumor protein, and the hybridomas which secrete them have been constructed. These monoclonal antibodies are useful in the detection, monitoring, and diagnosis of malignancies characterized by inappropriate expression of the WT1 protein.

Abstract: The present invention provides a panel of monoclonal antibodies and binding proteins which specifically bind to human Fas antigen. Some of the antibodies and binding proteins are capable of stimulating T cell proliferation, inhibiting binding of anti-Fas CH-11 monoclonal antibody to cells expressing Fas antigen, blocking anti-Fas CH-11 monoclonal antibody-mediated lysis of cells, and blocking Fas ligand-mediated lysis of cells. The invention also provides for therapeutic compositions comprising the monoclonal antibodies.
