Fig. 5: Identification of differentially expressed proteins in response to oxidative damage by iTRAQ.

a, b MS/MS spectra used for the identification of H2A and MAT2A, respectively. c MAT2A protein levels were detected by western blotting to validate the iTRAQ results. GAPDH was used as a normalization control. Molecular weights are indicated on the left: MAT2 (60 kDa) and GAPDH (37 kDa).
