Figure 6: BPV-1E5-PDFGβR colocalization. (a) BPV-1 E5 (green fluorescence) and PDFGβR (red fluorescence) markedly colocalized (merged panel, yellow fluorescence) in a juxtanuclear Golgi-like position in sarcoid-derived EqS02a cells transfected with BPV-1 E5 (EqS02aE5). A representative image is shown. (b) EqS02a cells expressed PDFGβR in the cytoplasm and showed no green signal for E5. Bar = 20 μm.
