RESUMO
We have derived hybridization probes from analogous 100-base-pair segments located within the N-terminal region of gp70 coding sequences which differentiate xenotropic from mink cell focus-forming (MCF)-related murine leukemia virus (MuLV) DNAs. The MCF probe annealed to the integrated proviruses of all six MCF MuLV isolates tested; the xenotropic probe hybridized to the DNAs of all four xenotropic proviral isolates examined. No cross-hybridization was observed, and neither probe reacted with the env segments of amphotropic or ecotropic MuLV DNAs. Southern blot analysis of HindIII- or EcoRI-digested genomic DNAs from a variety of inbred laboratory mice demonstrated the presence of more MCF- than xenotropic MuLV-related segments in every strain tested.
