±×¸². Tet-One System Mechanism - The Tet-On 3G transactivator protein is expressed constitutively from
the human PGK promoter (PPGK) but is unable to bind to the TRE3G promoter (PTRE3G) in the absence of doxycycline
(Dox). When bound by Dox, supplied in the culture medium, the transactivator undergoes a conformational change, binds to
PTRE3G and activates transcription of a transgene cloned downstream.

±×¸² 2. Seven out of eight Tet-One clones show more than 1,000-fold induction of expression.
HeLa cells were infected with LVX-TetOne-Puro-Luc lentivirus (M.O.I. = 1) and eight individual clones were
selected and expanded according to the protocol. Each clone was analyzed for doxycycline-induced expression
of luciferase. Seven of the eight clones demonstrated more than 1,000-fold induced expression, including
two clones with 5,000-fold induction, and one clone with 10,000-fold induction.
