  • Patent number: 6593137
    Abstract: This invention provides a hybridoma produced by the fusion of a mouse antibody-producing cell and a mouse myeloma which is designated 1-10F-8A and deposited with the ATCC under Accession Number PTA-279, said hybridoma producing a monoclonal antibody which binds to fullerene C60. This invention provides a mouse monoclonal antibody specific for a fullerene-C60 and produced by the mouse monoclonal antibody-producing hybridoma designated 1-10F-8A. The invention provides the amino acid and encoding nucleic acid sequences of the heavy and light chains of the 1-10F-8A monoclonal antibody. This invention also provides methods of determining a serum concentration of a fullerene in a subject and of purifying a fullerene from a sample.

  • Patent number: 5604092
    Abstract: Monoclonal antibodies to cyclosporine A (CsA), a potent immunosuppressant, were generated in Balb/c mice using a novel antigen prepared by linking CsA to a protein carrier via a photoactive cross-linking reagent, 4-benzoylbenzoic acid (BBa). Twenty-two monoclonal anti-CsA antibodies were generated, using CsA-BBa-bovine serum albumin (CsA-BBa-BSA) as the immunogen. Epitope mapping studies were performed using a series of singly substituted CsA derivatives and an antibody was identified that recognizes N-methyl leucine residues 9 and 10 of CsA. This antibody also cross-reacts with the HIV-1 Gag protein. A method for the detection of HIV-1 in patient samples employing this monoclonal antibody is disclosed.
