Fig. 2. Frequency distribution of Vbl in 120 cells from
collecting tubules and collecting ducts. (A) The Vbl of
collecting duct cells (N=50) fell into two groups, one being more
hyperpolarized than the other. (B) Vbl of collecting
tubule cells (N=70) showed a broader distribution with the mean
Vbl falling inbetween that of the two collecting duct
groups.
