Table 2.

This table summarizes the fluorescence lifetime results from cell measurements in the presence and absence of amsacrine, the fluorophore quencher

	0 μM	18.6 μM	27.9 μM	37.2 μM
EB intensity percentage decrease	0%	2%	19%	24%
EB mean lifetime (tau1)	15.9 ns	15.2 ns	14.6 ns	14.0 ns
EB mean lifetime (tau2)	0.9 ns	0.9 ns	0.7 ns	1.3 ns
Mean reduced-Chi-square errors	3.88	4.34	2.9	4.1

The two-lifetime components determined are listed as the reduced mean χ² for the comparison between experiment and model. The average decrease in fluorescence intensity is also provided.
