Depositor 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.
