Tet-On 3G transactivator lentiviral particles

Premade lentivirus to express the Tet-On 3G transactivator

Highly concentrated and purified lentivirus for delivery of the Tet-On 3G transactivator to target cells. Any gene of interest (GOI) under the control of a TRE3G promoter (P_TRE3G) can be tightly controlled by the presence and absence of doxycycline (Dox) in the culture medium.

Highly concentrated and purified lentivirus for delivery of the Tet-On 3G transactivator to target cells. Any gene of interest under the control of a TRE3G promoter can be tightly controlled by the presence and absence of Dox in the culture medium. Tet-On 3G is a modified, improved Tet-On Advanced transcriptional activator protein (transactivator) which has been evolved to display far higher sensitivity to the inducer molecule dox. Tet-On 3G generates very high maximal expression and responds to lower Dox concentrations than its predecessors.

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. Documents Components Image Data Back Fetal bovine serum (FBS) approved for use with tetracycline-inducible expression systems 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 Our fetal bovine serum is functionally tested to guarantee consistent results with tetracycline-inducible expression systems 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. Back 631101: Tet System Approved FBS, US-Sourced

Overview

What does 10⁹ TU/ml mean?
- In each microliter, there will be at least 1 x 10⁶ functional lentivirus particles.
- Each 60-µl kit is sufficient for 30 transductions (using an MOI of 10) in a 6-well plate containing 2 x 10⁵ cells/well.
Gold standard tetracycline transactivator in a ready-to-use lentivirus format.
Premium quality; produced via a multistep purification process which results in very high titers and purity.
- Functional titer provided, not a just a particle count.
- High purity—transduce target cells without cytotoxicity.
- >90% transduction efficiency can be obtained even at very low MOI.
Can be combined with any vector containing a TRE promoter to obtain tetracycline-inducible expression of your gene of interest (we recommend the TRE3G promoter).

Super-pure and concentrated premade lentivirus particles

Unlike ready-to-use lentiviral particles from other suppliers, the particles in our catalog are produced via a multistep purification process that results in very high titers and high purity. High titers increase transduction efficiency, while high purity reduces cytotoxicity, allowing you to successfully transduce a large number of different cell types—including primary, immortalized, adherent, and suspension cells—while retaining high cell viability.
