WebLC3 is the most commonly used marker to evaluate autophagy levels by IHC but requires careful analysis. High levels of cytosolic LC3 make it difficult to clearly see LC3 associated with autophagosomes. It is also common to see false positives due to the nonspecific granular staining pattern of cytoplasmic components (Martinet et al. 2024).

WebA growing body of evidence suggests that autophagy occurs in advanced atherosclerotic plaques. Vascular smooth muscle cells, macrophages, or endothelial cells treated … WebLC3-II, especially LC3B-II, is the only well-characterized protein which is specifically localized to autophagic structures throughout the process from phagophore to lysosomal degradation. Although larger in molecular mass, LC3-II shows faster electrophoretic mobility in SDS-PAGE gels (potentially because of increased hydrophobicity).
