FIG. 7.

Immunoblot analysis of protease-treated EEV. Purified EEV particles were digested with proteinase K (PK) or trypsin (T), and Western blot analysis was performed with the antibody indicated at the bottom of each panel. While A33R and A34R were sensitive to proteolytic digestion, A36R was largely protease resistant. Undigested EEV samples were used as controls (CON). Molecular mass markers are indicated in kilodaltons.
