Gene function

Tetracycline inducible expression—Tet-One systems

tet-inducible expression using a single vector

Before the Tet-One systems were developed, our Tet-On and Tet-Off products all required two separate vectors: one to introduce the doxycycline-responsive transactivator protein into your target cells, and the other to introduce the inducible promoter controlling your gene of interest.

The Tet-One Systems provide both of these components on a single vector. The Tet-On 3G transactivator is expressed in the forward direction from the human phosphoglycerate kinase 1 promoter, and the cloned gene of interest is expressed from the P_TRE3GS promoter in the reverse orientation. Compared to the two-vector Tet-On 3G systems, all previously published all-in-one vectors have shown a low signal-to-noise ratio, typically providing only 50- to 100-fold induced expression, even in selected clones. Our Tet-One systems are based on an all-in-one design that has shown up to 25,000-fold induction (Heinz et al. 2011).

The AAVpro Tet-One Inducible Expression System is a tetracycline-inducible gene expression system that allows you to produce high titers of recombinant, adeno-associated virus (AAV) for establishing a tightly inducible expression system for your gene of interest in mammalian cells. The all-in-one pAAV-TetOne vector expresses the Tet-On 3G transactivator from the constitutive human PGK promoter, and your gene of interest from the P_TRE3GS promoter. 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. There is no selection marker on this vector for mammalian cells. The kit also includes the plasmids for preparation of high-titer AAV particles without the use of a helper virus, and AAV Extraction Solution for isolation of pure AAV particles.

The Retro-X Tet-One Inducible Expression System (Puro) is a tetracycline-inducible retroviral gene expression system that allows you to produce high titers of recombinant retroviruses for the purpose of establishing a tightly inducible expression system for your gene of interest in a wide variety of dividing mammalian cells. The all-in-one pRetroX-TetOne-Puro 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. In addition, this vector contains a puromycin antibiotic selection marker. The kit also includes our Retro-X Universal Packaging System, our premium retroviral packaging system featuring the GP2-293 packaging cell line. All four commonly used envelopes are supplied on separate vectors, including VSV-G, eco, ampho and 10A1, to allow you to choose the tropism that is most appropriate for your target cells.

The Tet-One Inducible Expression System is a tetracycline-inducible gene expression system that allows you to establish a tightly inducible expression system for your gene of interest in mammalian cells using an all-in-one plasmid vector. The pTetOne 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. In addition, the kit contains linear selection markers for resistance to puromycin and hygromycin, either of which can be cotransfected with the pTetOne Vector to obtain stable clones. It also includes Xfect Transfection Reagent and Tet System Approved FBS.
