Timetable for the sensitizations and challenges in the study. Epicutaneous sensitizations were performed twice in one week intervals, followed by an immunological maturation period. Intragastric (i.g.) administrations (50 mg/mL of ovalbumin) were started on day 38, and repeated 10 times. The mice were sacrificed on day 58, 60 min after the last i.g. administration.
