The present invention provides a human-mouse myeloma analog, designated HMMA 2.11TG/O, which has been deposited with the American Type Culture Collection (ATCC) under Accession Number HB 9583. The invention also provides a hybridoma designated F 105, which also has been deposited with the ATCC under Accession Number HB 10363. The invention also concerns a monoclonal antibody-producing hybridoma produced by the fusion of the human-mouse myeloma analog and an antibody-producing cell. Other embodiments of the invention provide a method for producing a monoclonal antibody-producing hybridoma which comprises fusing the human-mouse myeloma analog with a human antibody-producing cell and a therapeutic method for treating a subject having a pathogen- or tumor-related disease which comprises administering to the subject a monoclonal antibody specific for the disease produced by the monoclonal antibody-producing hybridoma. In addition, a method of blocking binding of the human immunodeficiency virus and method of preventing infection of human cells by the human immunodeficiency virus are disclosed, as well as methods of detecting the virus or its antigen.

IgG-1 human monoclonal antibody reactive with an HIV-1 antigen and methods of use

The present invention is directed to a recombinant human monoclonal antibody which binds to a discontinuous epitope on the HIV gp120 envelope glycoprotien, blocks the binding of gp120 to the CD4 receptor, and neutralizes a broad range of HIV isolates. The present invention also provides the primary nucleotide and deduced amino acid sequences of the rearranged heavy and light chains of the recombinant monoclonal antibody of the present invention, and a method of screening for antibodies which block binding of envelope glycoprotein to the CD4 receptor.
