Figure 5. Comparisons of precursor mass tolerance effects on search time and protein identifications.

Figure 5

An ovarian tumor secretome dataset was searched using SEQUEST as described in “Materials and Methods.” (A) Search time using different precursor mass tolerances. (B) Overlap of PSM and protein identifications between the 1.1 Da and 100 ppm precursor mass tolerance searches. Numbers of PSMs and proteins unique to each search condition are listed below the precursor mass tolerance. Filtered non-redundant peptide identifications were used.
