Figure 3From: A new strategy for faster urinary biomarkers identification by Nano-LC-MALDI-TOF/TOF mass spectrometrySpecific peptides MS signal intensity versus time after plate storage at 3 different temperatures (25°C, 4°C, -20°C). (a) human angiotensin II (MW = 1046.54), (b) neurotensin (MW = 1672.91), (c) ACTH fragment 18–39 (MW = 2465.19), and (d) oxidized insulin B chain (MW = 3494.65). Error bars represented SD from triplicate measurements.Back to article page
