Reproducible Automated Phosphopeptide Enrichment using Magnetic TiO2 and Ti-IMAC.

Data from ProteomeXchange, PXD ID: PXD000892. File: FIG5_1_KRAS_G12D_3.msf.mgf. Published as part of Anal Chem. 2014 Sep 18 . From the Abstract: {{i}} Reproducible, comprehensive phosphopeptide enrichment is essential to study phosphorylation-regulated processes. Here, we describe the application of hyper-porous magnetic TiO2 and Ti-IMAC microspheres for uniform automated phosphopeptide enrichment. Combining magnetic microspheres with a magnetic particle-handling robot enables rapid ..., reproducible ... and high-fidelity ... phosphopeptide purification in a 96-well format ... {{/i}}
