Notes
In the diBA(5)C4 study, two of the six (Norm I NBC)−1 values obtained at 20 μM diBAC + 40 μM DIDS were not included in our analysis because they appeared to be outliers. These two values (8.63 and 9.91) had a mean (Norm I NBC)−1 of 9.27, which was 2.3-fold larger than the mean value of 3.96 obtained from the other four experiments.
