Figure 6: 2D-DIGE analysis of H9C2 cell proteome in response to H2O2 and quercetin treatment. H9C2 cells were lysed and arranged for a triplicate electrophoresis using pH 3 to 10 nonlinear, 24 cm IPG strips, and SDS-PAGE after treatment. 2D-DIGE image of protein sample (Cy2) is shown here. The spot numbers represent differentially expressed proteins.
