Fig 1. Proteomics results.

A) A summary of the protein groups identified from sweat via in-solution digestion. B) A Venn diagram of the protein groups identified from in-solution and in-gel digestion. C) Box-whisker plot of the number of MS¹ charge states selected for MSⁿ scans. D) Images of coomassie stained gels from 175μg sample loaded based on Nanodrop and 2μg sample load based on Bradford Assay. Data shows a small number of protein groups are identified from single sweat samples resulting from a high number of +1 charged peptides and a large group of low molecular weight proteins/peptides.
