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 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.

Overview

All-in-one vector design provides all the power of Tet-On 3G technology in a single vector, making inducible expression as easy as constitutive expression
Low background and high maximum induced expression
High sensitivity to doxycycline: near maximum expression at 10 ng/ml doxycycline
Inducible expression in a broad range of tissues, because the Tet-On 3G transactivator is expressed from the human PGK promoter
High-titer lentivirus packaging system provided with Lenti-X Tet-One systems
Retro-X systems incude our Retro-X Universal Packaging System
The AAVpro system uses a helper-free packaging system and includes extraction reagents for efficient isolation of AAV particles

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.
