Plasmid 11648: pLVPRT-tTR-KRAB
Comments: 

Transgenes can be expressed from any RNA Pol II promoter as part of
bicistronic unit comprising the KRAB-based repressor; tetO sequences
are inserted into the vector LTR. Tet-on and Tet-off versions rely on
repressors that bind in the absence or the presence of doxycycline,
respectively. Addition of Pol III promoter-small hairpin RNA cassette
allows for drug-controllable RNA interference (Tet-on shRNA).
