CFTR and infection: Similar to what was observed for scAAV2, 24 hr after inoculation of single-stranded rAAV2, the expression of GFP (Fig. 3A) or Luc (Fig. 3B) reporters indicated that infection was significantly more efficient in ΔF508-CFTR-expressing cells than in control or CFTR-overexpressing BHK-21 cells.
