Figure 10. ES-MS/MS analysis of a tryptic fragment with mass of 628 (in QTOF) and 1,272 (in MALDI-TOF) from the 9 kDa I isoform

Note the oxidation of M-146 residue in γD-crystallin isofrom I. A similar oxidation of methionine residue was also seen in the 9 kDa isoforms II and isoform III (not shown).
