Tet-Off Advanced IRES Fluorescent Vector Set

Description

The Tet-Off Advanced IRES Fluorescent Vector Set allows you to establish a tightly regulated and highly responsive inducible system for simultaneous coexpression of your gene of interest and a fluorescent protein marker. The system is turned off by adding doxycycline to the culture medium. The pTet-DualOFF Vector expresses the Tet-OFF Advanced transactivator along with the green fluorescent protein, ZsGreen1, to allow you to sort for high-expression of the transactivator in target cells. With pTRE-Dual2, Tet-inducible coexpression of your gene of interest and the red fluorescent protein, mCherry, is controlled by the TRE-based promoter, PTight. Coexpression of two genes from a single transcription unit in each of these vectors is made possible by an internal ribosome entry site IRES2 that separates the two coding sequences. pTRE-Dual2-Luc is an inducible control vector that coexpresses mCherry and luciferase. To select stable cell lines, the vectors must be cotransfected with one of the provided linear selection markers. Our products are to be used forResearch Use Only.

Back Monitor inducible expression using mCherry.pTRE-Dual vectors are supplied with the Tet-On Advanced IRES Fluorescent Vector Set Cat. # 631112 and Tet-Off Advanced IRES Fluorescent Vector Set Cat. # 631113 and provide simultaneous inducible expression of your transgene and our mCherry fluorescent protein from an IRES bicistronic mRNA. When your gene is turned on, so is mCherry, and your cells fluoresce red. Back IRES fluorescent vector sets Cat. # 631112, 631113 .The Tet-Dual transactivator expression vectors constitutively express either the Tet-On Advanced or Tet-Off Advanced protein, and the fluorescent protein, ZsGreen1 Panel A . pTRE-Dual2 is a Tet-regulated inducible expression vector that coexpresses mCherry and a second gene that is cloned in the multiple cloning site MCS Panel B . pTRE-Dual1 Cat. # 631114 coexpresses two user-defined genes. Back IRES fluorescent vector sets Cat. # 631112, 631113 .A 14-day old, puromycin-resistant colony of HEK 293 cells cotransfected with pTET-DualOFF, pTRE-Dual2-luciferase, and a linear puromycin selection marker exhibits dual fluorescent colors Panel A . The clone expresses Tet-Off Advanced protein and is green due to coexpressed ZsGreen1. In the absence of Dox, the cells are also red because Tet-Off Advanced protein activates the coexpression of luciferase and mCherry. The inducible expression of luciferase activity in this clone was measured and is shown in Panel B.. Back
