FIG. 6.
Morphology of VLP2/6 containing mutated VP6 proteins. Sf9 cells were coinfected by the baculoviruses expressing GFP fused to VP2 and the QDNL mutant of VP6. The VLP were purified by CsCl density gradients, and both the upper (A) and lower (B) bands were analyzed by negative staining. The protein content of each band was analyzed by PAGE (C). Shown are the results for the upper (lane 1) and lower (lane 2) bands; the results for wild-type VLP2/6 are also shown for comparison (lane 3).
