When used with any Lenti-X™ Tet-On® 3G or Tet-Express™ inducible expression system, the pLVX-TRE3G Vector Set allows for lentiviral delivery and inducible expression of your gene of interest in a wide variety of mammalian cells. Target cells that contain a gene of interest under the control of a PTRE3GV promoter will express high levels of your gene of interest, when cultured in the presence of doxycycline (when used with the pLVX-Tet3G Vector and a Tet-On 3G system) or in the presence of the Tet-Express tetracycline transactivator (when used with Tet-Express Systems).
