cAMP at 10 μm causes maximal activation of CFTR

cAMP concentration (μm)	cAMP‐evoked CFTR current (nA)	n
400	−1484 ± 132	11
200	−1776 ± 282	8
10	−1610 ± 207	10

cAMP‐evoked CFTR current: summary of two experiments; the difference in effect between the three cAMP doses was not significant (P = 0.611, one‐way ANOVA).
