FIGURE 2

Relative luminescence units emitted by firefly LUC (A) and Renilla LUC (B) activity across a range of dilution factors applied to Nicotiana benthamiana leaf extracts. Firefly LUC activity is inhibited by concentrated N. benthamiana leaf extracts. 20-fold dilution of a 5 mg per 100 μL extract is required to diminish the inhibitory effect.
