Figure 2From: Selection of recombinant MVA by rescue of the essential D4R genePlaque formation of dMVA-ZG and wild-type MVA in avian DF-1 cells. cDF-1 (a, b) and wild-type DF-1 (c, d) cells were infected with 100 pfu/well of dMVA-ZG (a, c) or MVA-wt (b, d). Four days post infection, immunostaining was performed with anti-vaccinia virus antibodies. Photographs show immune-stained plaques.Back to article page
