The piggyBac-based double-inducible binary vector system: A novel universal platform for studying gene functions and interactions

Eukaryotic inducible overexpression systems, including Tet-On and mifepristone-inducible systems, have been widely used to study gene functions by reverse genetics. Among the transposon systems reported to date, the piggyBac transposon system is one of the most efficient in cultured mammalian cells. Here, we report a piggyBac-based double-inducible system that combined the advantages of previous systems. To create this system, the trans- and...
