Transmission electron micrographs (TEM) of uranyl acetate-stained native virions and purified VLPs after incubation at different pH. Native virions, purified VLPs containing both AmCPV S1 and S3 encoded proteins, or AmCPV S3 encoded protein alone was incubated at pH-4 (A), pH-7.3 (B), and at pH-12 (C) and analyzed by TEM at 50 kV. Bar 100 nm.
