Figure 4From: A new strategy for faster urinary biomarkers identification by Nano-LC-MALDI-TOF/TOF mass spectrometryQuantitative performance of MALDI-TOF/TOF for the determination of the following peptides spiked at increasing concentrations in blank urine: Human angiotensin II (1046.54 Da, higest concentration 1X = 120 fmol/μl), neurotensin (1672.91 Da, 1X = 80 fmol/μl) and ACTH 18–39 fragment (2465.19 Da, 1X = 100 fmol/μl). Each sample was analyzed six times.Back to article page
