Distributions of peptide lengths identified by LTQ and QTOF platforms as a function of residue modifications. (A) Peptide length distribution of unique peptides when modifications are discounted for the QTOF (red) and LTQ (gray). (B) Peptide length distribution of unique peptides when modifications are taken into account for the QTOF (red) and LTQ (gray). (C) The distribution of modified and non-modified peptides identified by the (C1) QTOF and (C2) LTQ platforms. Data are summarized in Data Sheets 2 and 3.
