Histograms depicting the molecular weight distribution of the identified proteins in each of the 8 experiments. The proteins from each individual experiment were grouped according to their calculated molecular weight and plotted as indicated. All Y-axis scales except for the ones in panels D and H have been standardized to facilitate cross-experiment comparison.
