Abstract
Shotgun proteomics involves the analysis of <span class="Chemical">peptides obtained by enzymatic digestions of proteins and subsequent ide<span class="Chemical">ntification via tandem mass spectrometry. This approach is an effective method for studying global protein expression in neuronal systems. The method described here is a quantitative shotgun neuroproteomics method using amine-specific isobaric tags for a relative and absolute quantitation (iTRAQ)-based workflow. We will provide the technical details for sample preparation, two-dimensional liquid chromatography, tandem mass spectrometry, database search, and statistical analysis to identify differentially expressed proteins. We will use a recent study on a rat model of multiple sclerosis, experimental autoimmune encephalomyelitis to illustrate the successful application of this method.Entities:
