Figure 3

(a) Viral titer measured in supernatants of A549 cells infected with PR8 virus (high or low m.o.i.), following incubation of the virus with 140 μg/ml HOP extract. Titer was determined 24 h p.i. by hemagglutinating assay and expressed as percentage of HAU compared to that from cells infected with untreated virus. Data are mean ± SD from three independent biological replicates, each one performed in two technical replicates (). and versus untreated infected cells by Student’s -test. (b) Western blot analysis of viral proteins from samples obtained as described in (a). Actin was used as loading control.
