The tettag system
WebThe TetTag system. The TetTag transgenic mice contain two transgenes: one transgene expresses tTA by Fos promoter and the other transgene expresses dox-insensitive tTA* and tau-LacZ downstream of the tetO promoter. Neuronal activity can trigger activation of Fos promoter and lead to the expression of tTA, the transactivator of the tetO promoter. WebAug 20, 2015 · In the 'TetTag' method, tetracycline controls the capture of activated neurons (using a self-activating tTA–TetO system), and the window of activity tagging is opened …
