Experimental protocol. Mice were sensitized weekly for four weeks intraperitoneally (i.p.) with 200 μg of CPE and 2 mg of alum and then challenged i.p with 1000 μg CPE 2 weeks after the last sensitization. To determine whether QC and/or QM extracts prevent peanut anaphylactic reactions, we administered QC or QM at 2 mg or 4 mg intragastrically (i.g.) to a group of mice twice daily for five weeks beginning at Day 0 of the protocol (n = 5-8 mice per group).
