Electrophoretic mobility quartiles from distributions of individual mitochondrial events. (A) mouse liver mitochondria on uncoated capillaries, (B) mouse liver mitochondria on AAP capillaries, (C) rat liver mitochondria on PVA capillaries, and (D) rat liver mitochondria on AAP capillaries. Open symbols represent data pooled from undersampled populations (<269 for rat liver mitochondria on PVA capillaries, <78 for all other samples). Graphs are presented in log scale along the x-axis to more easily perceive all the data. Legend: ■ first quartile, ◆ median, and ▲ third quartile.
