Figure 1. Basophil activation test to egusi seed. A dose response curve illustrating the proportion of CD63+basophils at increasing concentrations of egusi seed extract from 0.1 ng/mL to 10,000 ng/mL. Positive controls are represented by anti-IgE (aIgE) and N-Formylmethionyl-leucyl-phenylalanine (fMLP).
