Proteomic analyses. Purified mitochondrial proteins from Ian4^+/+ WF and Ian4^-/- BBDP rat T cells resolved by SDS/PAGE. Bands 1, 2, and 5 were differentially expressed in Ian4^+/+ vs. Ian4^-/- T cells, excised, and identified by MALDI-TOF mass spectrometry. Not all differentially expressed bands were examined. Bands 3 and 4, which were similarly expressed, were excised to verify the purity of the mitochondrial isolation. Identities and gene identifiers for excised bands are indicated. Shown is one of two similar gels.
