Figure 2From: A software application for comparing large numbers of high resolution MALDI-FTICR MS spectra demonstrated by searching candidate biomarkers for glioma blood vessel formationDistribution of the mean isotopic distances μ j of real isotopic clusters as a function of the mono-isotopic peptide mass in the glioma vessels sample H2. The dashed lines represent the acceptance window, between μs – σs and μs + σs of mean isotopic distances of real isotopic clusters. The larger mass accuracy with larger peptide masses is reflected by the larger scatter of isotopic distances μjBack to article page
