载体简介:
The pSingle-tTS-shRNA vector expresses the tetracyline-controlled transcriptional suppressor (tTS), which controls expression of an shRNA sequence inserted into the shRNA cloning site. The tTS protein is a fusion of the Tet repressor protein (TetR) and the KRAB-AB silencing domain of the Kid-1 protein (SDKid-1 ), a powerful transcriptional suppressor (1, 2). In the absence of the inducer doxycycline (Dox, a tetracycline derivative), tTS binds to the tetO sequences in the modified Tet-responsive Pol III hybrid promoter (P Tight/U6 ) and blocks expression of the shRNA. As Dox is added to the culture medium, tTS dissociates from P Tight/U6 to allow Pol IIImediated transcription of the shRNA, resulting in suppression of the target gene in a highly dose-dependent manner. pSingle-tTS-shRNA also contains a ColE1 origin of replication and an ampicillin resistance gene (Amp r ) for propagation and selection in bacteria, as well as a neomycin resistance gene (Neo r ) for selection of stable transformants in mammalian cells.
