Fig. 5: Assessment of antibodies induced in mice immunized with the four sE2 glycoforms at day 56 post-immunization by ELISA.

Each datum represents the mean of duplicate experiments for each serum sample. A Total IgG endpoint titers. B IgG1 endpoint titers. C IgG2a endpoint titers. Endpoint titers were calculated by curve fitting in GraphPad Prism software with the endpoint OD defined as four times the highest absorbance value of day 0 sera.
