Figure 6.
Accumulation of protein group identifications during nine successive replicate analyses of tryptic peptides from colon adenocarcinoma tissue, as classified by the number of distinct peptides that characterized each protein. The data are taken from the analyses described in Figure 5. Listed are proteins that were identified by 2 distinct peptides within a single replicate MS/MS run, those identified by 3 or 4 peptides, by 5 through 9 peptides and by 10 or more peptides. Proteins that are identified by higher average numbers of distinct peptides have higher probabilities of detection in a single replicate MS/MS run.
