Much recent and ongoing research is focused on understanding the mechanisms and regulation of autophagy, a cellular self-degradation pathway with many links to human health. Although many assays exist to measure the total magnitude of autophagy, electron microscopy remains the tool of choice for the determination of the size and the number of autophagosomes formed in a given mutant or under given induction conditions. Here we present a detailed protocol for measuring autophagic bodies in the yeast Saccharomyces cerevisiae by electron microscopy. Furthermore, we present an improved mathematical method for estimating body size and a new method for estimating body number. Finally, we include a discussion of the merits and limitations of these methods and an example of their application to autophagic bodies formed in the ume6? strain.
