Figure 3From: Co-administration of avian influenza virus H5 plasmid DNA with chicken IL-15 and IL-18 enhanced chickens immune responsesStable expression of Vero cells with (a) pDisplay vector, (b) pDis/H5. Recombinant H5 proteins expression was detected by IFAT assay and visualized in bright field (BF) and fluorescence (F). Vero cells transfected with pDisplay vector as negative control.Back to article page
