Figure 7.

Histograms showing the number of proteins identified with a given number of unique peptides for each individual experiment. The number of validated, non-redundant peptides was calculated for each protein identified within the context of each individual experiment, and proteins having identical numbers of peptides were grouped together and plotted as indicated. The Y-axes (number of proteins) for the experiments indicated in panels C and D and in A, B, E, F and G have been standardized in order to facilitate cross-experiment comparison.
