Figure 3.

Kinetics of the decay of liposome-encapsulated NN⁺ measured by EPR during enzymatic generation of HNO (○). HNO was generated by catalase, 2 mg/ml, from cyanamide, 10 mM, in the presence of 5 U/ml glucose oxidase and 5 mM glucose[43]. Addition of glucose oxidase/glucose was used as a source of hydrogen peroxide. The symbols (□) denote the kinetics measured in the same system but in the presence of 1 mM glutathione.
