Optimization and direct comparison of the dimerizer and reverse tet transcriptional control systems

Exogenously controlled gene expression systems are essential for both the in vivo analysis of gene function and the regulated delivery of therapeutic gene products. However, differences in experimental methods used to characterize the various systems prohibit informative comparisons. The purpose of this study was to identify an optimal system for regulated gene expression studies through a rigorous direct comparison of the dimerizer and the reverse tet transactivator (rtTA) transcriptional switch systems.
