|Further information:||The construction of this plasmid is described in De Groote et al. (2016).
This is a lentiviral Gateway destination vector, with the tet-inducible minimal human CMV-IE promotor and rtTA3 on the same plasmid.
The plasmid is suitable for microRNA expression.
The U3 region of the HIV-1 3' LTR is deleted (ΔU3 or dU3) and facilitates self-inactivation of the HIV-1 5' LTR after transduction to enhance the biosafety of the vector. The element also contains a polyadenylation signal for transcription termination and polyadenylation of mRNA in transduced cells.
The vector contains the psi packaging signal, allowing viral packaging, and the rev response element (RRE) from HIV-1, permitting Rev-dependent nuclear export of unspliced viral mRNA.
Depending on the gene cloned in this vector, some leakage expression may be detected.
Because the risk for recombination after each subcultivation is high, this plasmid is only available under the format of isolated plasmid DNA. Plasmid integrity should be checked via PvuII restriction digest after each subcultivation.
This Gateway destination vector is compatible with the human orfeome library which is also available at BCCM/GeneCorner.
This vector can not be used to express short hairpin RNA (shRNA), which requires an RNA-polymerase III promotor. However, this vector can be used for knock-down experiments if the hairpin is expressed in a micro-RNA context (eg. Block-iT PolII miR RNAi kit).
The nucleotide sequence of the pDG2i-HA puro vector corresponds with the EMBL Nucleotide Sequence Database accession number LT009445.1.
Other names of the plasmid are pDG2lenti_HA rtTA3 puro, pDG2iTag-puro and pDG2i-HA-puro.
