FIG. 5.

Release of a VSV PY mutant is not blocked by MG132. (A) Titers of the AAPA mutant virus present in the supernatant of cells infected in the absence (−) or presence (+) of MG132 (50 μM). Virus titers and standard deviations represent averages of three independent experiments. (B) Immunoprecipitation of radiolabeled VSV M protein from cell extracts (cells, lanes 2 and 3) and media (media, lanes 2 and 3) of cells infected in the absence (−) or presence (+) of MG132 (50 μM). Mock-infected samples are shown in lane 1 in both sections.
