Outward rectification
WebJan 1, 2010 · Instead of outward rectification predicted by the Nernst equation, they showed greater flow into rather than out of the cell (Fig. 1A). Kir currents were therefore originally … Webcellular acidification, strong outward rectification, activa-tion kinetics during application of depolarizing pulses, lack of dependence on intracellular Ca2+ and sensitivity to 4,4′-diisothiocyanatostilbene-2,2′-disulfonic acid (DIDS). How-ever, the role of this acid-sensitive outwardly rectifying (ASOR) anion channel remains unknown.
