Ad5Luc1-PK vector provides augmented gene transfer.

<p>Luciferase activities following infection of cancer cell lines with Ad5Luc1-PK (filled columns) and Ad5Luc1 (open columns). Luciferase activity was determined 24 hours post-infection and reported in relative light units, RLU. Each column is the average of 4 independent replicates using 100 v.p./cell. Error bars indicate standard deviation.
