Identification of Urinary Peptide Biomarkers Associated with Rheumatoid Arthritis
Figure 2
Urinary polypeptide signatures in cases and controls from the validation set based on 39 significantly different sequenced peptides.
Normalized molecular weight (500–15000 Da) in logarithmic scale is plotted against normalized migration time (18–45 minutes). The mean signal intensity of the polypeptide peak is given in 3-dimensional depiction (n = 15 controls and 16 cases).
