Abstract: Highly efficient enrichment of phosphopeptides in low abundance prior to mass spectrometry analysis is essential in phosphopeptidomics analysis. Herein, an affinity probe possessing both interactions of polyoxometalates (POMs) and hydrophilic interaction chromatography (HILIC) was facilely…
