Analyzing the vRNA genome packaging efficiency of the recombinant viruses. Five recombinant viruses [rA/PR/8/34 (A), Swap(wt) (B), Reassortant(NS) (C), Reassortant(HA) (D), and Swap(mut) (E)] were grown in eggs at 37 °C and purified viral RNA was separated (0.5 μg/lane) on a 2.8% acrylamide gel and visualized by silver staining. The RNA from the rA/PR/8/34 (A) and Swap(mut) (E) viruses was separated on one gel, and the RNA from the other three viruses [Swap(wt) (B), Reassortant(NS) (C), and Reassortant(HA) (D)] was separated on another gel.
