Mesoporous TiO2-Based Experimental Layout for On-Target Enrichment and Separation of Multi- and Monophosphorylated Peptides Prior to Analysis with Matrix-Assisted Laser Desorption-Ionization Mass Spectrometry

Ulf Anders Hagfeldt, Anna Eriksson, David Malmström

A simple method for on-target enrichment and subsequent sepn. and anal. of phosphorylated peptides is presented. The tryptic digest of a phosphorylated protein, in this case β-casein, is loaded onto a spot on a thin stripe made of mesoporous TiO2 sintered ...
