Takara, 634307, Retro-X™ Tet-One™ Inducible Expression System (Puro)

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 thePTRE3GSpromoter 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.
