Figure 5.

The UV-Vis spectra of 100 μM nTAM in the presence of HX/XO superoxide generating system ([HX] =0.25 mM, [XO] =10 mU/ml) in 0.1 M phosphate buffer solution, pH = 7.4 (dotted lines corresponds to different incubation times of 6, 13 and 25 minutes). Solid line represents the UV-Vis spectrum of nTAM in the absence of HX/XO.
