Abstract |
Shotgun proteomics has been used successfully for more than two decades for measurement of proteins from diverse biological systems. This has led to new insights and identification of potential biomarkers and drug targets for numerous medical conditions. The advent of mass-labeling approaches such as isobaric tagging for relative and absolute quantitation (iTRAQ) has allowed multiplexing of samples to improve the accuracy and throughput of experiments and the reduction of costs. Here, we describe a detailed iTRAQ mass spectrometry protocol for simultaneous analysis of four proteomes from postmortem brain tissue extracts. In addition, a post-labeling procedure for peptide fractionation is presented. |
