Levels of OVA-specific IgE measured in mouse serum on day 26 after OVA-post treatment with AbM. Mice were injected with 10 μg of OVA on day 0 and given 200 μl of AndoSan™ extract or PBS intragastrically on day 19, before OVA booster on day 20 and sacrifice on day 26. Values are given in AU/ml and means + 1 s.e.m. for groups of 16 mice (groups of 8 per each of 2 experiments). Anti-OVA IgE levels were lower in AbM (AndoSan™) than PBS treated groups (p = 0.048, two-way ANOVA).
