Isolation of autophagosomes, autolysosomes, and lysosomes allows mechanistic studies into the pathophysiology of autophagy—a lysosomal quality control pathway. Here, we outline a Nycodenz density gradient ultracentrifugation approach for high-yield isolation of autophagic fractions from mouse liver. These fractions can be used for immunoblotting, transmission electron microscopy, and proteomic and lipidomic analyses. For complete details on the use and execution of this protocol, please refer to Toledo et al. (2018).
