Abstract
Transgenic flies expressing GFP-mCherry-Atg8a (obtained from the Bloomington Drosophila Stock Center)  
under the control of the  neuronal nSyb-GAL4 driver are used for assaying autophagic flux.
Transgenic flies expressing GFP-mCherry-Atg8a (obtained from the Bloomington Drosophila Stock Center)  under the control of the  neuronal nSyb-GAL4 driver are used for assaying autophagic flux
Brains from 10-day-old animals are dissected in ice-cold 1X PBS
The dissected brain are transferred to a glass slide
The remaining 1X PBS is removed from the slide
A drop of DAPI Fluoromount is added and the brain mounted with a coverslip
The dissected brain is imaged immediately within 5 minutes using a Zeiss confocal microscope under a 63X objective lens, and a line scan performed
For quantification, the intensity of GFP and mCherry is measured per puncta using ImageJ, and the ratio between GFP and mCherry calculated
