Processed MALDI-TOF MS spectra. (A) The 2500-10000 m/z range of the log mean spectrum from each study (all spectra from EAT in red, 2EAT in black) showing the consistency of the data between the two studies and the peak at 7600; (B) A close-up of 2EAT mean spectrum (in black) with peak-location density histograms from all spectra in each study (EAT in gray, 2EAT in blue) shows there are approximately 30 peaks in the 9300-10000 range and the ZAG fragment at 9560 m/z appears consistently on the shoulder of the peak at 9520 m/z.
