Appeal No. 1995-4400 Application 07/694,302 CLAIMS: 1. A hybridoma which produces a Friend murine leukemia virus (FMuLV) specific monoclonal antibody specific for an antigenic determinant of a gp85 envelope precursor protein characteristic of a methanol-fixed F-MuLV infected cell. 2. The hybridoma according to claim 1, wherein said hybridoma results from the fusion of a myeloma cell and a spleen cell. 3. The hybridoma according to claim 2 wherein said myeloma cell is derived from a mouse. 4. The hybridoma according to claim 3 wherein said myeloma cell is X63-Ag8.653. 7. A hybridoma producing monoclonal antibody 720, IgG1. 8. A hybridoma producing monoclonal antibody 721, IgG2a. 9. A hybridoma producing monoclonal antibody 722, IgG2a. 10. A hybridoma producing monoclonal antibody 723, IgG3. 11. A monoclonal antibody having the binding characteristics of the monoclonal antibody produced by the hybridoma according to claim 7, or binding fragment thereof. 12. A monoclonal antibody having the binding characteristics of the monoclonal antibody produced by the hybridoma according to claim 8, or binding fragment thereof. 13. A monoclonal antibody having the binding characteristics of the monoclonal antibody produced by the hybridoma according to claim 9, or binding fragment thereof. 14. A monoclonal antibody having the binding characteristics of the monoclonal antibody produced by the hybridoma according to claim 10, or binding fragment thereof. 15Page: Previous 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 NextLast modified: November 3, 2007
