Detailed Description

data structure for pattern of isotopic peaks

Groups of peptides appear as characteristic patterns of isotopic peaks in MS1 spectra. For example, for an Arg6 labeled SILAC peptide pair of charge 2+ with three isotopic peaks we expect peaks at relative m/z shifts of 0, 0.5, 1, 3, 3.5 and 4 Th.
