Family of ProxyPhos chemosensors: a toolbox for the detection of proximally phosphorylated biologically-relevant phosphate species.
A serum phosphopeptide (DpSGEGDFLAEGGGVR) was demonstrated to be a potential biomarker for gastric cancer diagnosis, particularly for early stage cases.
A composite assembled by mesoporous TiO2 and flowerlike NiO nanosheets can significantly improve the selectivity and sensitivity for phosphopeptide enrichment.
The sequential enrichment of mono- and multi-phosphopeptides was successfully achieved using two novel Ce-based nanocomposite affinity probes.
An optimized ILM G3THAP/PA matrix significantly improved the detection of phosphopeptides by negative ion MALDI-MS compared with using 3-AQ/CHCA/ADP and DHB/PA matrices.
