摘要

TMT labeling enables the simultaneous quantification of protein expression from multiple experimental conditions when coupled with the high resolution/accurate mass of the Orbitrap instruments. High pH reversed-phase fractionation of unenriched and phospho-peptide enriched samples resulted in over 7,800 protein groups identified and over 5,500 proteins quantified from ten different experimental conditions. Protein expression ratios from TMT ion reporters correlated well with previous SILAC studies and western blot analysis. Cluster analysis revealed differences in regulation of key ErbB pathway signaling proteins.
