Similar experiments were performed with Ad5-CB-CFTR virus to assess the 
efficiency of recombinant CFTR expression in the xenografts. Non-CF xenografts 
were exposed to 10^ pfu/ml of virus and subsequently explanted, frozen, 
cryosectioned, fixed, and immunostained using the CFTR COOH terminal antibody. 
Figure 7 shows immunocytochemical analyses of Ad5-CMV-lacZ infected grafts 
(panel A - Nomarsky, and panel B - fluorescence) and Ad5-CB-CFTR infected 
grafts (panel C - Nomarsky, and panel D - fluorescence).
