TetOn-3G, an ideal controller of mammalian gene expression with TRE-3G promoter+PolyA

Tet-On(Tetracycline-Controlled Transcriptional Activation,also known as rtTA2S-M2) is a system of inducible gene expression systems for mammalian cells. Tet-On 3G (also known as rtTA-V16[citation needed]) is similar to Tet-On but was derived from rtTA2S-S2 rather than rtTA2S-M2. The Tet-On 3G protein has 5 amino acid differences compared to Tet-On which appear to increase its sensitivity to Dox even further. Tet-On 3G is sensitive to 100-fold less Dox and is 7-fold more active than the original Tet-On.[http://en.wikipedia.org/wiki/Tetracycline-controlled_transcriptional_activation#Tet-On_Advanced_and_Tet-On_3G]

Target cells that express the Tet-On 3G transactivator protein and contain a gene of interest (GOI) under the control of a TRE3G promoter (PTRE3G) will express high levels of your GOI, but only when cultured in the presence of doxycycline (Dox), which is a synthetic tetracycline derivative(the mechanism of Tet-On 3G system show below). And the Dox concentrations required for induction of Tet-On Systems are far below cytotoxic levels for either cell culture or transgenic studies.
