Résumé

Proximity ligation in situ assay (PLISA) is a powerful method to quantify endogen protein-protein interactions in cells and simultaneously identify localization of these interactions. PLISA can be used to quantify autophagy flux and can as well be adapted to assess global autophagy (SQSTM1/P62-LC3B interaction) or specific autophagy, such as mitophagy (NIX-LC3B). Here, we describe a step-by-step method to monitor autophagy using PLISA in adherent cancer cells.
