Levels of OVA-specific IgE measured in mouse serum on day 26 after OVA-pretreatment with AbM. Mice were given 200 μl of AndoSan™ extract or PBS intragastrically on day -1 and injected with 10 μg of OVA s.c. in the tail base on day 0 and again on day 20, before exsanguination for serum on day 26. Values are given in arbitrary units (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 in PBS treated groups (p = 0.002, two-way ANOVA).
