Figure 3: Growth kinetics and HA titres of HA/NA chimeric viruses in Vero cells.
From: Development of high-yield influenza A virus vaccine viruses
(a) Growth kinetics and HA titres of UW-PR8-based viruses with wild-type or chimeric Indo09 HA and NA genes. (b) Growth kinetics and HA titres of viruses possessing the UW-PR8 backbone in combination with Indo09 HA and NA genes, or the PR8-HY backbone in combination with wild-type or chimeric Indo09 HA and NA genes. Experiments were carried out as described in the legend to Fig. 2. The values presented are the average of three independent experiments±s.d.
