Figure 2: Differential proteins spots of rat liver proteins (model group) on 2DE gel. First dimensional separation was performed on an immobilized nonlinear pH 3–10 strip, followed by the second-dimensional separation on 12% SDS-PAGE. The protein spots were visualized by silver staining. A total of 54 protein spots showed significantly different expression between normal and model groups by image analysis and comparison and are marked with green circles and red ID codes.
