    Abstract

    Autophagy plays a major role in physiological and pathological processes. The quantitation of the abundance of autophagy-specific substrates constitutes an efficient strategy for assessing autophagic activity. Here, we provide a detailed protocol for quantifying the decay of a fusion protein composed by enhanced green fluorescent protein (EGFP) and glutamine repeats (Q74) using regular or high-throughput fluorescence microscopy. This method provides a direct measurement of autophagic flux in a Huntington's disease model.
