HEK 293 Tet-Off Advanced Cell Line

Description

HEK 293 Tet-Off Advanced is a transformed human embryonic kidney-derived cell line that expresses the tetracycline Tet -regulated transactivator Tet-Off Advanced. Inducible expression of any gene can be achieved by transfecting or transducing this cell line with a vector containing your gene of interest under the control of a tetracycline-responsive promoter. Expression is induced by the withdrawal of doxycycline Dox from the culture medium. Tet-inducible cell lines are shipped with Tet System Approved FBS and a control cell line created for inducible expression of luciferase. Our products are to be used forResearch Use Only. They may not be used for any other purpose, including, but not limited to, use in humans, therapeutic or diagnostic use, or commercial use of any kind. Our products may not be transferred to third parties, resold, modified for resale, or used to manufacture commercial products or to provide a service to third parties without our prior written approval. Back Inducible expression using Clontechs HEK 293 Tet-Off Advanced Cell Line.Cells transfected with a pTRE-Tight-luciferase vector express very high levels of luciferase in the absence of doxycycline Dox . Basal expression is undetectible in the presence of Dox. Required Products Fetal Bovine Serum FBS that has been functionally tested for optimal use with all of our Tet Systems. This FBS does not contain trace levels of tetracycline or derivatives which have been observed to interfere with proper regulation of TRE-controlled gene expression. Use of this serum ensures the maximal range of induction possible with the Tet Systems. This FBS has been processed in the United States. Back Fetal bovine serum FBS approved for use with tetracycline inducible expression systems.Only Takara Bio USA functionally tests FBS to be sure that no contaminating tetracycline derivatives interfere with induced expression levels. Back Fetal bovine serum from Clontech is functionally tested to guarantee consistent results with tetracycline-inducible expression systems.Serum from other vendors that have not been functionally tested may contain tetracyclines that affect the maximum expression in Tet-Off systems, or generate background in Tet-On systems. Data here shows induction of luciferase expression from our CHO-AA8-Luc Tet-Off Control Cell Line using different sources of FBS.
