Tetracycline Inducible Expression—Tet-One Systems

Before the Tet-One Systems were developed, Clontech’s 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 PTRE3GS 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 50–100-fold induced expression, even in selected clones. Clontech’s Tet-One Systems are based on an all-in-one design that has shown up to 25,000-fold induction (Heinz et al, 2011).

  At-A-Glance   Documents   Images & Data   Resources


  • All-in-one vector design provides all the power of Tet-On 3G 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 System incudes 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


  • Tightly controlled inducible expression in mammalian cells
