Fig. 3From: Porcine circovirus type 2 ORF3 protein induces apoptosis in melanoma cellsPCV2 ORF3 overexpression induces nucleus fragmentation. B16F10 cells were transfected with either pcDNA3.1 empty plasmid (a and c) or pcDNA-ORF3 plasmid (b and d) and fixed 48 h post-transfection. Endogenous tubulin was stained with a FITC-labeled anti-α-tubulin antibody (green) in panels a and b. DNA was stained with DAPI (blue). Scale bars 5μmBack to article page
