Abstract: which produces avian leukosis virus gag and pol proteins, we have constructed packaging cells with subgroups B, C, and E envelope specificities. This allows us to produce helper-free avian leukosis virus particles carrying the lacZ reporter gene and the A, B, C, or E subgroup specificities. Titers of the recombinant lacZ virus are shown to be dependent upon the type of the env subgroup and the target avian cell.
