Fig. 10. Kinetics of Cys-DNIC as detected with EPR in HEPES (100 mM, pH 7.4). (A) With 20 mM cysteine, 200 m-M NO-proline, 50 mM Fe2+ and 250 mM sodium citrate. (B) With 20 mM cysteine, 200 mM NO-proline, 100 mM Hb, 50 mM Fe2+ and 250 mM sodium citrate. (C) With 20 mM cysteine, 400 mM Cys-NO, 50 mM Fe2+ and 250 mM sodium citrate. At the arrow, 100 mM Hb is added to scavenge NO and (D) With 20 mM cysteine, 400 mM Cys-NO, 100 mM Hb, 50 mM Fe2+ and 250 mM sodium citrate. (From Ref. [19].)
