A The fluorescence images and B the relative fluorescence intensity (FI) of the injection site in mice after injecting with HBsAg, HBsAg/Al and HBsAg/HPLNP formulations at a concentration of 1 µg HBsAg per mouse, for varying time periods. C The fluorescence images and D the FI of mesenteric lymph nodes after injecting with HBsAg, HBsAg/Al and HBsAg/HPLNP formulations at a concentration of 1 µg HBsAg per mouse, for varying time periods. Tukey's multiple comparisons test was used for statistical analyse
