LIT serum demonstrates a reduced capacity to elicit RBL mediator release compared to AAD serum. RBL assays were performed as described above. For AAD and LIT samples, twofold serial dilutions starting at 500 ng/ml OVA-IgE were performed. For naïve animals, samples were diluted using twofold serial dilutions from 1:1 to 1:8 concentrations. β-hexosaminidase release was measured as a percentage of total release in control samples. n = 6–8 per group. ^ap < 0.05 vs naïve, ^bp < 0.05 vs LIT
