Fig. 8. Membrane association of Apg16L depends on Apg5 but not on Apg5 conjugation
with Apg12. APG5-/- ES cells stably expressing GFP-Apg5
(GFP24) (A) or GFP-Apg5K130R (GKR-1) (B), wild-type ES cells (C)
and APG5-/- ES cells (D) were cultured in Hanks' solution
for 2 hours. The cells were fixed, permeabilized and subjected to
immunofluorescence confocal microscopy using an antiserum against Apg16L
(p63C-2) and Cy5-conjugated goat anti-rabbit IgG secondary antibody.
GFP-Apg5(KR) labeling, Apg16L staining, merged, and differential interference
contrast (DIC) images are shown. Bars, 10 µm.
