Properties of phosphopeptides and unmodified peptides identified after IMAC enrichment, TiO2 enrichment, or no enrichment. All values shown are the average number of unique sequences identified per biological replicate and error bars display standard deviation. Median values for each distribution are marked with solid, dotted, or dashed lines. A. Length of phosphorylated peptides. B. Length of unmodified peptides. C. Isoelectric point of phosphopeptides. D. Isoelectric point of unmodified peptides. E. Grand average hydropathy (GRAVY) values of phosphorylated peptides. F. GRAVY values of unmodified peptides.
