Mean pepmix TMT ratios were evaluated based on the extent of co-isolation in the corresponding peptide spectrum match. The data was plotted in a cumulative fashion displaying the mean TMT ratio of the fraction of pepmix data below the respective co-isolation threshold (A). Median-centered peptide abundance distribution for each TMT channel (sample) in (B) the TMT set comprised of individual samples and (C) the TMT set consisting of pool CSF samplesBack to article page
