Morphology of influenza virus treated with GTE. a Cryo-EM images of PR8 virus treated with PBS or GTE. 5 × 107 PFU of PR8 virus was incubated with PBS or 0.1% GTE 0.1% for 24 h at 25 °C before observation under cryo-EM. Two images of the virus treated either PBS or GTE 0.1% are shown. b Analysis of the size distribution of PR8 virus treated with GTE or PBS by dynamic light scattering (DLS). 5 × 107 PFU of PR8 virus was incubated with PBS or GTE (0.01, 0.05, and 0.1%) for 24 h at 25 °C. After the incubation, the size distribution of the virus was analyzed by DLS. The results of intensity distribution are shown. The red box indicates the particle size at the highest intensity
