Identification of foods that may cross-react with ragweed pollen by using murine model of sensitization with ragweed pollen and allergenic protein microarray technology. (A) Allergenic protein microarray analysis was performed using serum from mice given intraperitoneal administration of ragweed pollen plus alum or PBS plus alum as a control, before analysis of murine model of OAS. (B, C) Balb/c mice (n = 5) were intraperitoneally injected with ragweed pollen plus alum six times at a 1- week interval. Serum levels of total IgE (B) and ragweed-specific IgE (C) from Balb/c mice after two, four or six times of intraperitoneal injection of ragweed pollen plus alum. Data are presented as mean ± SD. Data are representative of two independent experiments. Brown-Forsythe and Welch ANOVA with Dunnett T3 multiple comparisons. *P < 0.05; **P < 0.01.
