概述	Autophagy, a degradative pathway that provides recycled nutrients to cells under stress, plays both protective and deleterious roles in many diseases, including cancer, neurodegeneration, and infections. Members of the LC3 family play a key role in the maturation of the autophagosome, the central organelle of autophagy. LC3 precursors are proteolytically processed to form LC3-I, which is diffusely distributed in the cytosol. Upon initiation of autophagy, the C-terminal glycine of LC3-I is modified by addition of a phosphatidylethanolamine (PE) to form LC3-II, which translocates rapidly to nascent autophagosomes in a punctate distribution. Given the pronounced changes in biochemical properties and subcellular localization of LC3 upon initiation of autophagy, detection of LC3 by various means has become the gold standard method for estimating autophagosome quantity within the cell. However, detecting and interpreting the relative amounts of LC3-I and LC3-II in standard assay methods can be complicated. When LC3 is immunochemically detected by Western Blotting following SDS-polyacrylamide gel electrophoresis, LC3-II typically appears as a slightly lower band than the 18 kDa LC3-I band as a result of the greater hydrophobicity of LC3-II. However, in some instances, the LC3-I and LC3-II bands are incompletely resolved, which complicates analysis. Also, even when LC3-I and LC3-II are adequately separated on an immunoblot, changes in the relative ratios of the isoforms may not be directly proportional to autophagosome quantity, due to differential immunoreactivity of the isoforms. Finally, there is confusion about whether the best indicator of autophagy is 1) absolute quantity of LC3-II, 2) the relative ratio of LC3-II to LC3-I alone, or 3) the relative ratio of LC3-I to the sum of LC3-I and LC3-II. A review solely devoted to interpretation of LC3 immunoblotting concludes that the absolute quantity of LC3-II is the best indicator of autophagy. EMD Millipore’s LC3-II Enrichment Kit (Western Blot) enables sensitive and accurate quantification of autophagosome density by utilizing a selective permeabilization procedure that removes cytosolic LC3-I and retains autophagosome-bound LC3-II. This procedure reveals quantities of LC3-II, without interference from LC3-I, by Western blotting analysis. The kit also includes a lysosomal inhibitor, to prevent degradation of LC3-II that occurs upon fusion of the autophagosome with the lysosome. In addition, an antibody against a mitochondrial outer membrane protein TOMM22 is included for use as a control for specificity of permeabilization, to ensure that organelles remain intact after treatment.
