FIGURE 4

The enhancements (positive values) or reductions (negative values) of NoV P particle detection in the presence of vegetable extract (romaine lettuce, cherry tomato, and spinach) compared with PBS controls (P particles diluted in PBS) tested by saliva-binding ELISA. The x axis represents the concentration of vegetable extract; the y axis represents the enhancements or reductions of OD450 (ΔOD450). Each data point is an average of triplicates, and each error bar represents the data range.
