Figure 7. Western blot analysis of expression of HA in pseudoparticle producer 293 cells and HA incorporation into pseudoparticles.
(A) Pseudoparticles and their producer 293T cell lysates were analyzed for AH H5 expression. Wild-type H5N1 virus A/Vietnam/1194/2005 (300 ng) was used as a positive control. (B) Pseudoparticles and their producer 293T cell lysates were analyzed for 09H1 expression. Wild-type H1N1 virus A/California/7/2009 (300 ng) was used as a positive control.
