From: Mass spectrometrical analysis of recombinant human growth hormone (Genotropin®) reveals amino acid substitutions in 2% of the expressed protein

Figure 5

MS/MS spectra of Genotropin® . LIFT-TOF/TOF (MS/MS) (a, b) spectra of Genotropin® generated by an Ultraflex™ TOF/TOF (Bruker Daltonics) operated in LIFT mode for MALDI-TOF/TOF fully automated using the FlexControl™ software. The parent ions (m/z 1205.56 and m/z 2342.12) were selected for further analysis by MS/MS and the amino acid sequences NYGLLYCFR (5a) and LHQLAFDTYQEFEEAYIPK (5b) were unambiguously assigned to human growth hormone.
