FIGURE 6.

Cross-inhibition of IgE binding between Blo t 21 and Der f 21. Cross-inhibition experiments of IgE binding were conducted using sera from five patients preadsorbed with 0.1, 1, or 100 μg/ml of Blo t 21 (solid line) or Der f 21 (dotted line). The percentage of inhibition of IgE binding were determined with plates coated with either Blo t 21 or Der f 21 and using patient sera preadsorbed with different concentrations of either Blo t 21 or Der f 21. The average from duplicates of a single experiment was plotted with their standard deviations.
