Figure 7.
Effect of specific motor antibodies on late endocytic vesicle motility. MT-bound late endocytic vesicles were incubated with antibodies to specific motor proteins, as indicated, for 6 min. Motility was then quantified after 50 μM ATP addition. The total number of MT-bound vesicles examined is shown in parentheses. *p < 0.0004 compared with buffer or nonimmune IgG.
