Table 3. Z′ , % Inhibition and Z′ × % Inhibition as calculated from the data shown in Fig. 10.

Protein conc. (nM)	Z′	% Inhibition	Z′ × % Inhibition
5,000	0.95	19	18.27
2,500	0.95	44	42.02
1,250	0.95	63	58.06
625	0.88	76	66.37
313	0.70	82	57.44
156	0.56	82	46.33
78	0.54	88	47.35

Z′ × % inhibition provides a good metric to identify the optimal range of protein concentration for use in screening
