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).
Cloning shRNA into pLVET, pLVCT, and pLVPT vectors: first clone shRNA into pLVTHM downstream of the tetO-H1 region.
Then cut pLVTHM containing your shRNA with MscI-FspI and clone the insert containing the 3'LTR to target plasmid opened
with MscI-FspI. FspI cuts into AmpR. This means for inverted clones AmpR will not be restored; after selection you will
be left with clones with the shRNA cassette and functional AmpR.
