Urine peptidome analysis. Top panel summarizes the MUDPIT discovery and MALDI MS confirmation processes. Bottom table lists the 13 confirmed urine peptide biomarker discriminating KD and FC. M/Z: mass to charge ratio. ΔSC: spectral counting difference. Post translation modifications: * hydroxylation; # methionine oxidation. U Test: P value. Abbreviations: FC, febrile controls; KD, Kawasaki disease; MALDI MS, Matrix-assisted laser desorption/ionization (MALDI) mass spectrometry; MUDPIT, multi-dimensional protein identification technology.
