Swiss Mouse Embryo Moloney Murine Leukemia Virus Transfected Fibroblast Cells (CRE BAG 2 Line)

CRE BAG 2 is a fibroblast cell line that was developed from the NIH 3T3 embryonic Swiss mouse cell line, which was transfected with Moloney murine leukemia virus-derived proviral genomes carrying complementary mutations in the gag-pol or env regions. The genomes were altered at the 3' end of the provirus and contained a deletion of the psi sequence needed for the efficient encapsidation of retroviral genomes into virions.
