(A) Base peak chromatogram for the LC-MS/MS analysis of spot 22. (B) through (D) MS/MS spectra for the three peptides ions from the LC-MS/MS analysis that matched to Xenopus laevis hypothetical protein MGC81232. The peptide ions (doubly-charged, [M+2H]2+, with precursor ion masses 567.25, 705.81, and 630.29) were matched to sequences NDQLVC#EQK (Xcorr 2.98; C# denotes carbamidomethyl-cysteine), EFEEDLSGVDDR (Xcorr 3.92), and NYIM*EFDVGR (Xcorr 3.02; M* denotes oxidized methionine), respectively.
