The post-translational modification of proteins by phosphorylation has been shown to regulate many aspects of cellular function from growth and differentiation to basic metabolism. Here we show that two phosphopeptide enrichment strategies (IMAC and Motif Antibody) are highly complimentary with an overlap of -6% in the number of unique, non-redundant phosphopeptide identifications.
