Ultrastructural localization of Apg9p for immunoelectron microscopy. Strain STY1 (pep4Δ) expressing 3×HA Apg9p was grown in YPD to log phase and transferred to SD(−N) medium for 2 h. The cells were fixed and stained with anti-HA antibody and 5-nm colloidal gold-conjugated goat anti–mouse IgG as described in Materials and Methods. A, Section showing autophagic bodies in the vacuole lumen. B, Section showing a cytosolic autophagosome. Apg9p is seen in patches near the vacuole, but not on autophagic bodies or autophagosomes. AB, autophagic body; AP, autophagosome; N, nucleus; V, vacuole; VM, vacuolar membrane. Arrows point to areas of concentrated Apg9p.
