The base vector pLKO.1-puro was developed1 at the Broad Institute as part of TRC. Our contribution to TRC is a diverse set of vectors for critical control experiments, as well as vectors for custom shRNA production. This page contains information pertaining to these vectors. [pLKO.1-puro sequence (without shRNA insert)](https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/vectors/plko.txt) [TRC1.5 Vector: pLKO.1-puro](https://www.sigmaaldrich.com#pLKO "TRC1.5 Vector: pLKO.1-puro") [TRC1.5 Control Vectors](https://www.sigmaaldrich.com#controlvectors "Control Vectors") [TRC1.5 Alternate Vector Backbones](https://www.sigmaaldrich.com#alternate_vector "Alternate Vector Backbones") [TRC2 Vector: TRC2-pLKO-puro](https://www.sigmaaldrich.com#TRC2 "TRC2 Vector: TRC2-pLKO-puro") [Inducible shRNA Vectors](https://www.sigmaaldrich.com#inducible "Inducible shRNA Vectors") [Lentiviral Packaging Vectors](https://www.sigmaaldrich.com#lentiviral "Lentiviral Packaging Vectors") [References](https://www.sigmaaldrich.com#References "References") ## [](https://www.sigmaaldrich.com)TRC1.5 Vector: pLKO.1-puro Vector and Use #### TRC1.5 clones are in the exact same vector backbone as the TRC1 clones Features of the pLKO.1-puro vector allow for transient or stable transfection of the shRNA as well as production of lentiviral particles.1 Stable gene silencing is selected using the puromycin selectable marker while self-inactivating replication incompetent viral particles can be produced in packaging cells (HEK293T) by co-transfection with compatible packaging plasmids.2,3 Exclusive to our portfolio, TRC1.5 contains almost 200,000 clones including more than 49,000 validated clones. It combines all of the content from TRC1 plus an additional 39,212 clones targeting 2,661 new human genes and 2,395 mouse genes. Unlike adenovirus or murine-based MMLV or MSCV retroviral systems, lentiviral-based particles permit efficient infection and integration of the specific shRNA construct into differentiated and non-dividing cells, such as neurons and dendritic cells, overcoming low transfection and integration difficulties when using these cell lines. Compared to siRNA and other vector-based systems, pLKO.1-puro provides solutions for long-term knockdown and phenotypic observation, transduction of difficult or sensitive cell lines (non-dividing cells or primary cells), and is an economical renewable resource. With an shRNA insert, the length of the pLKO.1-puro plasmid is 7,086 bp, as indicated in the vector map below. Without an shRNA insert, pLKO.1-puro vector has a length of 7,052 bp. The sequence file provided is the empty pLKO.1-puro vector (7,052 bp).

The only change between the TRC1.5 vector and the TRC2 vector is the addition of the WPRE (or the Woodchuck Hepatitis Post-Transcriptional Regulatory Element).4 This allows for enhanced expression of transgenes delivered by lentivirus.5 As with TRC1.5, stable gene silencing is achieved by using the puromycin selectable marker. Self-inactivating replication incompetent viral particles can be produced in packaging cells (HEK293T) by co-transfection with compatible packaging plasmids. TRC2-pLKO-puro provides solutions for stable long-term knockdown and phenotypic observation, transduction of difficult or sensitive cell lines (non-dividing cells or primary cells), and enhanced expression of transgenes. With an shRNA insert, the length of the TRC2-pLKO-puro plasmid is 7,518 bp, as indicated in the vector map below. Without an shRNA insert, the TRC2-pLKO-puro vector has a length of 7,484 bp. The sequence file provided is the empty TRC2-pLKO-puro vector (7,484 bp).

In the absence of IPTG (isopropyl-β-D-thio-galactoside), an analogue of lactose, LacI binds to LacO preventing expression of the shRNA. When IPTG is present, the allosteric LacI repressor changes conformation, releasing itself from lacO modified human U6 promoter, and subsequently allows expression of the shRNA. We are proud to offer two different IPTG inducible vectors for your research. The preferred inducible vector, [pLKO-puro-IPTG-3xLacO](https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/147/343/plko_iptg_3xlaco.pdf), contains three lac operon sequences (two in the U6 promoter and one 3' of the promoter) affording both tight regulation and great gene silencing. Whereas, the [pLKO-puro-IPTG-1xLacO](https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/200/058/plko_iptg_1xlaco.pdf)  vector contains a single lac operon sequence in the U6 promoter, which allows for an advantage to shRNA expression, but looser control of the promoter when not induced. | | | | | |-----------------------|---------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | __Product__ | __Purpose__ | __Vector Map__ | __Vector File__ | | pLKO-puro-IPTG-1xLacO | Alternate vector backbone | [pLKO-puro-IPTG-1xLacO](https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/200/058/plko_iptg_1xlaco.pdf "pLKO-puro-IPTG-1xLacO Vector Map pdf") | [pLKO-puro-IPTG-1xLacO](https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/vectors/plko-iptg-1xlaco.txt "pLKO-puro-IPTG-1xLacO Vector File") | | pLKO-puro-IPTG-3xLacO | Alternate vector backbone | [pLKO-puro-IPTG-3xLacO](https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/147/343/plko_iptg_3xlaco.pdf "pLKO-puro-IPTG-3xLacO Vector Map pdf") | [pLKO-puro-IPTG-3xLacO](https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/vectors/plko_iptg_3xlaco.txt "pLKO-puro-IPTG-3xLacO Vector File") | ## [](https://www.sigmaaldrich.com)Lentiviral Packaging Vectors Finally, for those wanting to package their own lentivirus, we offer the optimized packaging mix.
