Levels of OVA-specific IgE measured in mouse serum on day 26 after either pre- or post-OVA treatment with AbM. Mice were either 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, or injected with OVA on day 0 and given AndoSan™ extract or PBS intragastrically on day 19, or given AndoSan™ extract or PBS both before (day -1) and after (day 19) OVA injection (day 0). All groups were OVA boosted on day 20 and sacrificed on day 26. Values are given in AU/ml and means + 1 s.e.m. for groups of 8 mice (p = 0.064, one-way ANOVA for difference between the groups).
