General description

Sigma^® is proud to offer IPTG-inducible vectors as the latest development from our continued partnership in TRC.

The pLKO vector has been redesigned to contain a LacI (repressor) and a modified human U6 shRNA promoter with LacO (operator) sequences. 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.

The MISSION 1X LacO Inducible TurboGFP^™ shRNA Control is a 8,684 base pair lentivirus plasmid vector that contains an shRNA sequence targeting TurboGFP.¹ The TurboGFP shRNA Control Vector is useful as a positive knockdown control in experiments using the MISSION TurboGFP positive control vector or in cell lines expressing TurboGFP. TurboGFP is an improved variant of the green fluorescent protein copGFP cloned from copepoda Pontellina plumata.

Ampicillin and puromycin antibiotic resistance genes provide selection in bacterial or mammalian cells respectively. In addition, self-inactivating replication incompetent viral particles can be produced in packaging cells (HEK293T) by co-transfection with compatible packaging plasmids.^2,3The TurboGFP shRNA Control Vector is provided as 10 μg of plasmid DNA in Tris-EDTA (TE) buffer at a concentration of 500 ng/μl.
