Fig. 3. M2e5x VLP immunization induces M2e-specific antibodies to M2 expressing MDCK cells.

Fig. 3

Immune sera were collected from BALB/c mice that were immunized with split vaccine alone (Split, N=12) or additional M2e5x VLP immunization after split vaccine (S-M2e5x, N=12). All sera were collected at 3 week after M2e5x VLP boost. (b) immunization. (A) Hemagglutinin inhibition (HAI) assay. Split-b(11wk): 11wk after Split-b. (B) Reactivity to synthetic M2e peptide. Split-b(7wk): 7wk after Split-b. Split-b(11wk): 11wk after Split-b. (C) Reactivity to M2-expressing MDCK cell. (D) Reactivity to influenza virus-infected MDCK cells. The dotted line denotes the limit of HAI detection. Error bars indicate mean ± SEM.
