P tight promoter

It is a response element containing 7 consecutive TetO elements and a minimal CMV promoter. When binding to tTA or rtTA, the expression of the downstream gene will be highly activated. Besides, it can achieve low constitutive expression(almost undectectable) when not binding to tTA or rtTA.

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.

functional assay of tTA

The 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.
