From: Extracellular redox sensitivity of Kv1.2 potassium channels
Calibrated effects of redox potential on Kv1.2 use-dependent activation. (A,B) Extracellular redox potential was clamped using membrane impermeant redox couples ((A), cysteine and cystine (Cys:CySS), or (B), reduced and oxidized glutathione (GSH:GSSG)) by varying the ratio of the two species while maintaining a total concentration of 100 µM. N = 13–15 for each redox potential.
