Figure 6
Effect of PS-F2 administration on the production of OVA-specific antibodies. Mice were immunized, treated, and challenged as described in Figure 1. (A) On day 14, serum levels of OVA-specific IgE were determined by ELISA. (B, C) On day 28, serum levels of OVA-specific IgG1 (B), and IgG2a (C) were determined by ELISA. n = 10 in all groups. Data shown are representative of 2 experiments. * P < 0.05, ** P < 0.01, *** P < 0.001.
