Figure 4From: The EIPeptiDi tool: enhancing peptide discovery in ICAT-based LC MS/MS experimentsExample of missing value. Selected Ion Chromatograms (SICs) illustrate how an H/L pair having the same m/z and retention time values of peptide QRQEELCLAR, identified in Sample 1 is also present in the LC-MS/MS data of Sample 3.Back to article page
