Inhibition of IgE-FITC binding by Mo-DCs. Immature dendritic cells (105) were treated with IgE-FITC (7 μg/ml) plus blocking IgE or IgG antibodies (20 μg/ml) for 20 minutes at 4°C and then washed and fixed. Analysis was done by flow cytometry. The results show a significant decrease in IgE-FITC binding when mixed with unlabelled IgE, but not control IgG (*: p value ≤0.05). The data presented represent the average of three independent experiments expressed as mean ± SEM.
