(A) Single-channel conductance of BK channels measured in bilayers of different lipid compositions and from HEK cells. Each bar represents a single-channel conductance measured in an individual experiment. The value above each composition is the probability that the set of scores observed deviates from normality as determined by the Shapiro-Wilk test of normality (Shapiro and Wilk, 1965). (B) Average slope conductance ± SD for each of the six lipid compositions. Probability values for each pairwise comparison are indicated in Table 1. In every case, significant values are assumed when p ≤ 0.05. N = number of recordings in each mean.
