Urine proteome analysis by C₁₈ plate–matrix-assisted laser desorption/ionization time-of-flight mass spectrometry allows noninvasive differential diagnosis and prediction of diabetic nephropathy - Fig 5

<p>(A) Representative LC-UV chromatogram of urinary proteins from a DM-NP subject. The eluent was collected at 60-s intervals. (B) MALDI-TOF MS analysis of LC subfractions 9, 10, and 11. The marker peak of <i>m/z</i> 15860 was found in fraction 10. (C) Identification of the corresponding peptide of the <i>m/z</i> 647.91 peak by nanoLC-MS/MS. The sequence of CC16 was shown and the identified peptide sequence was underlined.
