2. Fig. 1
Efficient transfection of mouse nasal epithelium with recombinant Sendai virus expressing β-galactosidase. Close to 100% of airway epithelial cells express β-galactosidase, here visible as blue precipitate.

3. Fig. 2
Detection of endogenous CFTR in human airway epithelial cells using an anti-CFTR specific antibody. Apically localised CFTR protein is visible as a green layer and the DAPI-stained cell nucleus appears in blue.

4. Fig. 3
Nasal potential difference measurements in CF and non-CF murine nasal epithelium. Following measurement of basal PD (BL), a solution containing amiloride (Am) is perfused into the nasal cavity, which leads to a drop of PD in CF and non-CF mice. Subsequently the nasal epithelium is perfused with a low chloride solution (LC), which generates a driving force for chloride secretion and increased PD in non-CF, but not in CF mice.
