β-galactosidase activity following in utero modification of CFTR expression. Bat-gal mice were injected at E15, E16, or E17 with adenoviruses expressing eGFP (control), antisense CFTR (ASCFTR), or CFTR and lungs harvested 24 hours later. Tissue was homogenized and β-galactosidase enzyme assays and total protein determinations performed. * p < 0.05.
