: We developed a rapid screening system using two reporter genes under the
control of the same promoter, to identify the biological activity of modifi
ed or/and vectorized antisense oligodeoxynucleotides (ODNs). The ability of
a dendrimeric structure and a monocationic cholesterol derivative to enhan
ce ODN cellular uptake was previously investigated by fluorescence analysis
. Then, the assay system was validated through investigating the effect of
both vectors on antisense ODN efficiency.
