Conductances of Xenopus Oocytes Expressing CFTR

Unstimulated		cAMP-stimulated
		24 h	48 h	72 h
Mock	2.9 ± 1.7 (11)	2.7 ± 1.4 (4)	2.9 ± 1.6 (4)	3.2 ± 2.1 (3)
hCFTR	4.2 ± 3.8 (35)	426 ± 60 (16)	685 ± 131 (13)	1,147 ± 217 (6)
XCFTR	3.1 ± 2.1 (34)	214 ± 50 (14)	1,009 ± 268 (14)	2,028 ± 217 (6)

Xenopus laevis oocytes were injected with water (mock), hCFTR cRNA, or XCFTR cRNA, and their membrane conductances were measured at 24, 48, or 72 h after injection with and without stimulation with cAMP cocktail. Conductances are expressed in microSiemens. Each result represents the mean ± SEM of n experiments (numbers in parentheses).
