Fig. 2. (A) The effect of changing the external K+ concentration on basolateral (Vbl) and transepithelial (Vte) membrane potentials in a paired experiment. Vbl hyperpolarizes in a low K+ concentration and depolarizes in a high K+ concentration. Vte hyperpolarizes as the K+ concentration increases. (B) Vbl as a function of log bath [K+] shows a slope of 28 mV decade-1; y=28x-70. Each point represents means ± S.E.M. of Vbl.
