Figure 3.
Cumulative unique peptide identifications obtained upon subsequent analyses up to ten replicates for BB12A, BB11A, BB10A, and BB9A (black, red, blue, and green diamonds, respectively). Results for a mixture containing 50 femtomoles per peptide from all four libraries are shown in open diamonds. Data for replicates of a tryptic digest of D. radiodurans are shown in open squares. The data point at one replicate represents the average number of unique identifications among all ten replicates, rather than the number in any one replicate.
