Protein concentration in ASL samples collected from the apical side of non-CF treated with 0.1 % DMSO (vehicle control) and CF HBEC treated with 0.1 % DMSO (vehicle control) or 1 µM of ivacaftor (iva), 5 µM of tezacaftor (tez), 5 µM of elexacaftor (ele) and 1 µM of ivacafotor + 5 µM of tezacaftor + 5 µM of elexacaftor (Mix) for 48 h. Protein concentration (µg/mL) was measured with the Bradford assay. Data are expressed as mean ± sem (standard error of the mean). n indicates the sample size.
