Fig. 2. Western blot of purified hepatitis E virus (HEV) 110-610 His-tag 54.6 kDa protein. Membranes were incubated with swine serum (A), human serum (B), and monoclonal antibody (anti-hepatitis ORF2 antibody) (C). M, protein marker; 1, HEV 110-610 N-end His-tag protein; 2, HEV 110-610 C-end His-tag protein (arrows).
