Vector stability. To assess vector stability, remaining sample fluid from each individual animal dosing was sprayed into 15 mL sterile polypropylene tubes and stored frozen in cryovials. Luciferase activity was measured. There was approximately 35% less luciferase activity from renilla viral vector (RL) and 27% less activity from the firefly viral vector (although the data were not significantly different) when sprayed (s) versus not-sprayed (ns) were compared. *p < 0.05.
