From: Improved proteome coverage by using iTRAQ labelling and peptide OFFGEL fractionation
Protein abundance index (PAI) for the identified proteins. (A) influence of the iTRAQ labelling: free-labelled vs iTRAQ peptides (from 200 μg of digested proteins fractionated by SCX chromatography); (B) influence of the fractionation mode: SCX vs OFFGEL (from 400 μg of digested proteins and labelled with iTRAQ reagent).
