Tet-On 3G tetracycline-inducible expression systems

Tet-On 3G inducible gene expression systems

Tet-On 3G tetracycline-inducible gene expression systems are the third generation of the most powerful, versatile, and widely cited inducible mammalian expression systems available. The Tet-On 3G system offers a significant improvement over Tet-On and Tet-On Advanced systems with significantly reduced basal expression and increased sensitivity to doxycycline, a tetracycline analogue.

Choice of Tet-On 3G vector formats

There is a range of available Tet-On 3G vector formats:

  • Tet-One systems (listed elsewhere) provide a complete inducible expression system on a single vector.
  • The Tet-On 3G Inducible Expression System (EF1alpha Version), our EF1-alpha promoter version of the Tet-On 3G system, provides consistent long-term expression of the Tet-On 3G transactivator, even in cell types known for their tendency to silence a CMV promoter over time, such as hematopoietic cells and stem cells.
  • Bidirectional promoter versions of the system allow you to induce expression of two genes from the same promoter—either two transgenes of your choosing, or a single transgene and a fluorescent protein. If your cells turn red or green after adding Dox, this confirms that your gene has been turned on and that you have selected a high-performing inducible clone.
  • Using IRES technology, we've married very tight gene expression control to a bright red fluorescent protein (mCherry) in the Tet-On 3G Inducible Expression System (with mCherry), and a bright green fluorescent protein (ZsGreen1) in the Tet-On 3G Inducible Expression System (with ZsGreen1). 
  • Retroviral and lentiviral formats include the PTRE3GV promoter, which is optimized for use in retroviral and lentiviral vectors. They are supplied with complete viral packaging systems.

Use tetracycline-approved serum for optimal results

With the greatly increased sensitivity of the Tet-On 3G system, it is more important than ever that the serum you use for your studies is guaranteed to be tetracycline-free. Only Takara Bio performs actual inducibility tests on a sensitive Tet-inducible cell line in order to provide an absolute guarantee that our serum will not affect basal expression in your Tet-On 3G experiments. Each Tet-On 3G system is supplied with 50 ml of our premium Tet System Approved FBS.

631337 Tet-On® 3G Bidirectional Inducible Expression System Each USD $993.00 *

The Tet-On 3G Bidirectional Inducible Expression System is a powerful, tightly regulated, tetracycline-inducible mammalian expression system that is controlled by the addition of doxycycline to the culture medium. This system allows the simultaneous expression of two genes of interest from a bidirectional, Tet-responsive promoter that binds the Tet-On 3G transactivator protein in the presence of doxycycline. It includes the pTRE3G-BI Vector Set, consisting of a bidirectional vector into which both genes of interest can be cloned and simultaneously expressed, a bidirectional control vector that contains the luciferase gene in one of the two possible cloning sites, and two linear selection markers for hygromycin and puromycin resistance—and the pCMV-Tet3G Vector, which constitutively expresses the Tet-On 3G transactivator protein from a CMV promoter. This system also includes our highly efficient Xfect Transfection Reagent and Tet System Approved FBS.

Tet-One tetracycline-inducible expression system, technology overview

Tighly controlled expression system that is as easy to use as any constitutive system

Until now, the best inducible mammalian expression systems have all required a two-vector format. Tet-One inducible expression systems are the only commercially available single-vector systems that can deliver a >10,000-fold difference in expression levels between induced and uninduced states.
