Figure Lengend Snippet: (A) CHO cells stably transfected with TMEM30a-GFP and then stained with CellMask™ Orange Plasma Membrane to mark the plasma membrane (top) then imaged by confocal microscopy. Co-expression of the appropriate orange fluorescent protein Organelle Light defined endoplasmic reticulum (row 2), or Golgi (row 3). TMEM30a-GFP expressing CHO cells were labeled with MitoTracker Red to identify polarized mitochondria (bottom). (B) Western blot for GFP or plasma membrane Na/K ATPase in density gradient fractions from HepG2 cells stably expressing TMEM30a-GFP.
