Fig. 7. The effect of vinblastine on cytoplasmic Alfy-positive vesicles. HeLa cells on coverslips were either left untreated or starved for 2 hours. When indicated, the cells were pretreated with 50 µM vinblastine. Fixed cells were stained with anti-Alfy antibodies and studied by confocal microscopy. Error bars indicate s.e.m. from five experiments.
