Phosphorylation, one of the most common and important post-translational modifications of
proteins, plays a critical role in signal-transduction, regulatory, and metabolic pathways.[1] …

In this study, we employed, for the first time, the Ce4+-chelated magnetic silica microspheres
to selectively concentrate phosphopeptides from protein digest products. Cerium ions were …

Mass spectrometry-based strategies are widely used for mapping of post-translational
