APOBEC3 is packaged at similar levels in WT and glyco-Gag mutant viruses in vivo. (A) Western blot of virions isolated from BL/6 and APOBEC3 KO mice infected with WT or glyco-Gag mutant viruses and probed with anti-APOBEC3 (Upper) or anti-MLV (Lower) antisera. (B) Western blot of cores isolated from WT and mutant M-MLV–infected BL/6 and KO mice. This experiment was performed six times with similar results. A3BL6, APOBEC3BL6; NS, nonspecific band (52).
