		±×¸².  Tet-One¢â 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.  Seven out of eight Tet-One¢â 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.
