WebSep 11, 2024 · Isolated ON-gating currents decayed at increasing rates with increasing membrane depolarization, and the amount of gating charges displaced saturates at high voltages. These are two hallmarks of currents arising from the movement of charged elements within the boundaries of the cell membrane. WebAug 19, 2003 · We proceeded to characterize the components of HERG gating. Fig. 1. Comparison of gating and ionic currents for ether-a-go-go (EAG) and HERG K + channels. EAG ( a) and HERG ( b) ionic current elicited by 300-ms depolarizations ranging from -50 to +30 mV, applied in 20-mV increments from a HP of -110 mV. bush hog logo clip art
