Stability and variation of metrics over a range of sample injection amounts. Stability and variation of metrics over a range of sample injection amounts. Serial dilutions of a tryptic digest of the CPTAC yeast reference proteome were analyzed in triplicate by LC-MS/MS on an LTQ instrument. Median values for each series were plotted according to the categories in Fig. 1. Error bars represent ±median error. Some values have been scaled as indicated in the panel legends. pep, peptide; IDs, identifications; med., median; ID'd, identified; fract., fraction; num, number; FWHM, full width at half-maximum; inject., injection.
