A Quantification of TMRM fluorescence by flow cytometry in U2OS:GFP‐parkin cells treated with 25 μM antimycin A (anti A), 25 μM antimycin A and 10 μM oligomycin (anti A + oligo), and 20 μM CCCP (CCCP) for the indicated time, represented as a fraction of fluorescence intensity compared to DMSO‐treated cells. Error bars represent the mean ± s.e.m. (n = 3 experiments).
