Figure 1:

MALDI-TOF MS spectra of acid-soluble insect proteins for an example population of Ganaspis cf. brasiliensis (Ximing, reference Sample 1) obtained using Method 1 (top), and Method 2 (bottom) as described in the Materials and Methods section. Spectra are shown baseline-subtracted, smoothed, with common scaling on the y-axis (−2000 to 40 000 Bruker Intensity Units), and covering the mass range from 2 to 20 kDa (with x-axis scale increments of 2 kDa).
