Generation of the dual fluorescent protein reporter system
(A) Schematic illustration of the pEGFP-cox8 reporter system.
(B) Schematic illustration of the pLVX-actin-mCherry reporter system.
(C) Live imaging of EGFP-Cox8-mCherry-Actin-HeLa cells within 16 hr. Arrow points to the observed dynamic changes of cell proliferation.
(D) Confocal microscopy observation of co-localization of GFP-COX8 on the mitochondria. The GFP-COX8-HeLa cells were stained with TMRE (200 nM) for 20 min before the examination by confocal microscopy. Scale bar: 10 μm.
