Figure 2From: Cyclic GMP protects human macrophages against peroxynitrite-induced apoptosisOxidising radical generation by GEA-3162. A – representative EPR spectra generated by GEA-3162 (300 μM) in the presence and absence of SOD (500 U.ml-1). B – SOD reduced the intensity of the GEA-3162 EPR signal by a maximum of 61%. *P < 0.05, ***P < 0.001 (Two-way ANOVA followed by post hoc Bonferroni's test; n = 6).Back to article page
