Images were collected with a Nikon ES80 epi-fluorescence microscope
equipped with a CoolSnap CCD camera using NIS-Elements software with
constant exposure settings and processed equivalently in PhotoShop.
ATG8-GFP localization as a reporter for autophagy was as described
by Eisenberg et al.29 (link) The percentage of
cells showing autophagy was based on counting at least 100 cells per
technical replicate, and the experiment was performed on two biological
replicates. Propidium iodide staining was performed as previously
described.29 (link)
