Phospho-screen plus

This workflow can be used to study phosphorylated species from complex samples such as cell lysates, tissues and biofluids. Samples are processed by trypsin digestion and phosphorylated peptides are enriched using titanium dioxide microparticles before further fractionation using strong cation exchange chromatography. This service uses 20hours of instrument time versus the 2hrs used for Phospho-screen. The increased instrument time is reflected in the number of phospho protein/peptide identifications.
