tTA
tTA is a fusion protein of tetR protein from E.coli and the transcription activation domain VP16 from simplex herpes virus. It can bind to the Ptight element in response to doxycyline, and activate the expression of gene downstream of Ptight element.[1]

Funtional experiment
We conducted the functional experiment by co-tranfected the plasmid contains tTA and the plasmid contains P tight into Bosc, one kind of HEK-293 cell lines.Noted that we did not use tTA advance due to time limit(we construct the plasmid contains tTA advance later), and we will try that later,for improvement of expression control.
After adding dox, the expression of dox is almost fully suppressed.
We also get the quantitive data by western blot, which will be submitted later.
