Transduction efficiency of tandem fiber viruses in A549, Caco-2, and IM-9 lymphoblast cell lines. Aliquots of 2 × 105 A549 fibroblast cells (A), Caco-2 intestinal epithelial cells (B), or IM-9 lymphoblast cells (C) were incubated with 103 virus particles/cell for each of the indicated virus constructs. After 24 h cells were harvested and assayed for total relative CAT enzymatic activity as previously described. Data are means of triplicates ± sample standard deviation.
