abstract = {Tryptic digests of alpha and beta-casein were investigated as model compounds to demonstrate the applicability of the proposed setup for phosphorylation profiling in protein analysis using quadrupole based collision-cell ICP-MS as phosphorus specific detector. Detection limits for phosphorylated peptides down to the sub pico-mole level have been obtained. As a complementary technique, electrospray ionisation mass spectrometry (ESI-MS/MS) with data base searching has been applied to further characterise the phosphorylated peptides detected.},
