Lentiviral Tet-One inducible expression systems

The Tet-One system allows you to generate inducible expression systems as easily as you would generate constitutive expression systems. Previous inducible expression systems required transduction of two separate vectors into your cells. With the Tet-One system, both the doxycycline-responsive transactivator and your gene of interest are combined on the same vector. This allows for an easier setup while maintaining the low background expression and up to 25,000-fold induction (Heinz et al. 2011) in response to doxycycline that is found in the Tet-On 3G systems.

Lenti-X Packaging Single Shots (VSV-G), a high-titer fourth-generation packaging system, is included with each Lenti-X Tet-One kit.

The Lenti-X Tet-One Inducible Expression System is a tetracycline-inducible lentiviral gene expression system that allows you to produce high titers of recombinant, VSV-G-pseudotyped lentiviruses for the purpose of establishing a tightly inducible expression system for your gene of interest in a wide variety of dividing and non-dividing mammalian cells. The all-in-one pLVX-TetOne Vector expresses the Tet-On 3G transactivator from the constitutive human PGK promoter in the forward orientation and your gene of interest from the P_TRE3GS promoter in the reverse orientation. In the presence of doxycycline (Dox), the Tet-On 3G transactivator specifically binds and activates high-level transcription from the inducible promoter that controls expression of your gene. This vector does not contain a selection marker. The kit also includes Lenti-X Packaging Single Shots (VSV-G), a complete fourth generation lentiviral packaging system, and a sample of Lenti-X GoStix.
