The analysis of MALDI spectra: peaks' statistics. Peak lists were generated automatically for each spectra taken using FlexAnalysis v.2.4 supplied by Bruker Daltonics. (A) Signal-to-noise values (S/N) for each individual peak were extracted from all of the mass spectra taken for each individual preparation in each experiment. (B) Peak quality factor (QF) values, as reported by the FlexAnalysis software. Analysed similarly to S/N values. (C) Peak resolution values (Res), as reported by the FlexAnalysis software. Panel (D) shows the skew of the Res distribution for each matrix/QD preparation. In all panels, all values were averaged over all the peaks from all the spectra (for each particular matrix/QD preparation) from each individual experiment, and are shown as means +/- STDEV, from 3 experiments for each matrix/QD preparation.
