  • Human monoclonal antibody to glycoprotein GPIII of varicella zoster virus
    Patent number: 5650319
    Abstract: The human monoclonal antibody to the glycoprotein gpIII of varicella zoster virus (VZV), and hybridoma producing same, are provided. The hybridoma is obtained by immunizing human lymphocytes with gpIII antigen in the presence of a mitogen, and selecting a monoclonal antibody which reacts with a cell monolayer ELISA plate but substantially does not react with a cell homogenate ELISA plate.

  • Monoclonal antibodies specific for HIV and hybridomas for their production
    Patent number: 5445960
    Abstract: Human IgG1 monoclonal antibodies are produced by hybridoma ATCC HB10074 and bind to gp120 of HIV.
    Type: Grant
    Filed: May 24, 1993

  • Human hybridomas and monoclonal antibodies which bind both gp41 and gp120 envelope proteins of human immunodeficiency virus
    Patent number: 5298419
    Abstract: The invention is directed to the human hybridoma designated MCA 86 and having A.T.C.C. Accession No. HB 9669 and human monoclonal antibodies produced by hybridoma MCA 86. Human monoclonal antibodies produced by hybridoma MCA 86 immunologically binds to both gp41 and gp120 envelope glycoproteins of Human Immunodeficiency Virus (HIV). These monoclonal antibodies are useful in the diagnosis of HIV infection.
