Figure 6. Western blot analysis of expression of NA in pseudoparticle producer 293 cells and NA incorporation into pseudoparticles.
(A) Pseudoparticles and their producer 293T cell lysates were analyzed for 09N1 and 09N1-s60 expression. Wild-type H1N1 virus A/California/7/2009 (300 ng) was used as a positive control. Mock, normal 293T cell lysate; pps, pseudoparticles. (B) Pseudoparticles and their producer 293T cell lysates were analyzed for AH N1 and AH N1+09s60 expression. Mock, normal 293T cell lysate; pps, pseudoparticles.
