Comparisons of stimulation levels of basophils (CD63 + CD203c+) in different dilutions of MC. Data were obtained from combined 21 measurements of three healthy individuals, and given as percentage (A) or MFI (B). Boxes show the ranges of 1st and 3rd quartiles and extreme values. Horizontal bars represent median values. The differences among the measurements of different dilutions were evaluated by Friedman Test. Wilcoxon Signed Rank test was used as post hoc test. p values were indicated above the boxes when a level of significance < 0.05 was reached in comparisons.
