|Abstract:||The detection and identification of O-phosphorylation sites in proteins with mass spectrometry remains a challenge. A common approach to analyse these modifications is to enrich phosphopeptides by immobilized metal affinity chromatography (IMAC) prior to mass spectrometric analysis. In this study two commercially available IMAC kits based on Fe(III)-ions immobilized on magnetic beads and Ga(III)-ions immobilized on a chelate-resin, have been investigated and the binding efficiency of peptide mixtures containing non-phosphorylated, singly, doubly and triply phosphorylated peptides have been tested.|
