Expression of mTH and mTH-WPRE in COS-7 cells.
Cytoplasmic perinuclear expression of mTH is indicated by immunofluorescence in COS-7 cells in the absence and presence of WPRE following transduction with the plasmid vector DNA or the empty vector (empty). Original magnifications, left column, × 20; right column, × 40.
