Survival of XF73-incubated MRSA cells after 5 min of incubation with 5 mM sodium azide with and without illumination^a

Condition	% Survival of MRSA cells with XF73 atb:
	0 μM	0.001 μM	0.005 μM	0.1 μM
XF73 alone + light	100 ± 0.15	99.9 ± 0.24	0.015 ± 0.01	0.00001 ± 0.000024
XF73 + sodium azide + light	100 ± 0.15	99.98 ± 0.18	8.6 ± 0.2	0.0001 ± 0.00015
XF73 + sodium azide without light	100 ± 0.21	99.98 ± 0.21	95.3 ± 0.3c	78 ± 0.5
XF73 alone without light	100 ± 0.13	99.98 ± 0.20	98.7 ± 0.28c	48 ± 0.9

^aIllumination was at 15.2 mW/cm² for 15 min.

^bThe results are the means of at least three independent experiments ± standard deviations.
