Abstract

Since the discovery of autophagy genes and proteins in the early1990s, numerous previously unknown physiological and pathological functions have been discovered for autophagy. At the same time, precise monitoring of autophagy has become important, and western blotting and fluorescence microscopy of the marker protein LC3 iswidely used for this purpose. Here, we describe a modification of the widely used method, number of LC3 dots per cell. This protocol provides the proportion of vesicular LC3 staining over the total LC3 staining in the same cell. The approach is well suitable for quantification of endogenous LC3.
