FM4-64 internalization in the deletion mutants.
Cells were incubated for 30 min with the lipophilic dye FM4-64. After a
45–60-min chase period in medium without dye, FM4-64 fluorescence was
examined. (A) JD52 (wild-type), (B) JD52 (10 mM NaN3 + 10
mM NaF added together with FM4-64), (C) RKY1511
(Δvps4), (D) RKY1509
(Δmos10), (E) RKY1590
(Δvps20), and (F) RKY1510
(Δsnf7). (Left) FM4-64 fluorescence.
