Strain Osborne-Mendel (B cell); BALB/c (myeloma)
The antibody immunoprecipitates p30, binds efficiently to S. aureus protein A, and works well in Western blotting assays for p30. The antibody reacts with the p30 group antigen (gag) from most MuLV.
Storage Conditions Liquid nitrogen vapor phase
Animals were immunized with spleen focus forming virus (SFFV) infected nonproducer normal rat kidney (NRK) cells in complete Freund's adjuvant. Spleen cells were fused with NS-1 myeloma cells.
Genes Expressed
immunoglobulin; monoclonal antibody; against p30 gag protein of murine leukemia virus (MuLV)
