Figure 4From: Mitochondrial proteomics on human fibroblasts for identification of metabolic imbalance and cellular stress Western blot detection of NDUFA9 and the loading control VDAC1 (porin). The samples were loaded in triplicate (6 μg protein/well) and the protein levels, NDUFA9 in relation to VDAC1, were compared for glucose versus galactose cultivation, for two different normal fibroblasts; NHDF-1 and NHDF-2.Back to article page
