It is for this reason that phosphophopeptides are rarely found in samples that did not pass through a phospho-enrichment step, highlighting the importance of performing enrichment steps in phosphoproteomic studies. The numbers of identified phosphopeptides and phosphorylation sites are extremely important to the quality of a phosphoproteomic analysis; therefore, the efficiency of the enrichment process is critical. Here, phospho-enrichment techniques are presented to offer insight into the applicability of these methods to different e
