Figure 2From: Synergistic inhibition of avian leukosis virus subgroup J replication by miRNA-embedded siRNA interference of double-target Transfection effect of recombinant expression vectors observed by fluorescence microscope. The miRNA-embedded siRNA expression plasmids were transfected into DF-1 cells and GFP expression was monitored at 48 h post-transfection by fluorescence microscopy (magnification 40×).Back to article page
