The Thermo Scientific Pierce Magnetic Titanium Dioxide Phosphopeptide Enrichment Kit is for isolating phosphopeptides from complex biological samples using titanium dioxide-coated magnetic beads.

Features of the Magnetic Titanium Dioxide Phosphopeptide Enrichment Kit:

Complete MS-compatible kit—includes ready-to-use binding, wash and elution buffers that are optimized for phosphopeptide enrichment and downstream analysis by MALDI and ESI mass spectrometry
Optimized for HTS—procedure validated for processing 1 to 96 samples at a time; complete entire assay in about 15 minutes using a KingFisher Flex Instrument
Stable affinity ligand—titanium dioxide is specially coated as a film on the magnetic particles
Selective—affinity system is selective for phosphorylated Ser, Tyr and Thr; exhibits minimal non-specific binding to acidic residues
Sensitive—affinity provides more than 1000 times greater sensitivity than traditional IMAC technologies; enables enrichment and MS-measurement of less than 100 fmol of phosphoprotein

The TiO2 ligand selectively binds peptides containing phosphorylated serine (Ser), tyrosine (Tyr) or threonine (Thr), enabling phosphopeptide enrichment from protease-digested samples. The isolated phosphopeptides are compatible for analysis downstream by mass spectrometry. The high-performance, iron oxide, superparamagnetic particles are validated and optimized for use with high-throughput magnetic platforms, such as the Thermo Scientific KingFisher 96 and KingFisher Flex Instruments. The beads also enable premium performance for simple benchtop applications using an appropriate magnetic stand.
