Expression of FDXR–GFP fusion proteins. a, 911 cells were transfected with wild-type (WT) or deletion mutant (MUT) FDXR–GFP construct and its expression assessed with fluorescence microscopy. MitoTracker Red specifically labels the mitochondria and colocalizes with the FDXR–GFP (green). b, The fraction of stable clones that expressed GFP after doxycycline withdrawal in clones transfected with the indicated genes and grown in selective media for 14 d.
