Figure 2From: Improved proteome coverage by using iTRAQ labelling and peptide OFFGEL fractionation MS/MS spectra of GALQNIIPASTGAAK (which allowed the identification of the Glyceraldehyde 3 phosphate deshydrogenase) from 200 μg of digested proteins fractionated by SCX chromatography. (A) free-labelled experiment; (B) iTRAQ labelling experiment.Back to article page
