Description

pCDH-Cuo-RFP-T2A-GFP (positive control virus). Cat# QM350VA. Supplier: SBI System Biosciences

Verify inducibility with this positive control vector for your SparQ Cumate Switch projects – co-express RFP and GFP from the inducible cumate switch promoter
  • Robust—increase expression up to 32-fold
  • Adjustable—tune expression levels by titrating the amount of cumate
  • Reversible—turn expression on, then off, then on again
  • Versatile—choose from all-in-one formats that co-express CymR and your gene-of-interest, or two-vector systems where CymR is expressed from a different plasmid
  • Powerful—suitable for in vivo applications

Overview

Move forward confidently with pre-built positive controls
Maximize the efficiency of your SparQ™ Cumate Switch System projects with the pre-built, ready-to-go pCDH-CuO-RFP-T2A-GFP SparQ Positive Control Vector. No need to create expression controls—we’ve got you covered so you can make sure the SparQ System is optimized in your lab with your cells. RFP and GFP reporters are co-expressed from the inducible cumate switch promoter, with co-expression mediated by a T2A element.
 
With SBI’s SparQ™ Cumate Switch System, you can get inducible gene expression in mammalian cells through the binding of cumate, a non-toxic small molecule, to CymR. CymR can be delivered to cells on its own lentivector (Cat.#s QM200PA/VA-2 and QM300PA/VA-1), or on the same lentivector as your gene-of-interest (Cat.#s QM800A-1 and QM812B-1). Expression levels of your gene-of-interest are tightly controlled and increase with increasing cumate concentration until maximum induction is reached—see as much as a 32-fold increase in gene expression. Even better, induction is reversible, so you can turn expression levels on and off. Delivering negligible background expression in the absence of cumate, the SparQ System is an excellent choice for achieving controlled levels of gene expression.

  • Powerful—suitable for in vivo applications

How It Works

Tightly-controlled, inducible gene expression

SBI’s SparQ Cumate Switch System delivers robust, titratable gene expression with low background through three components:

  • Cumate, a non-toxic, small-molecule inducer
  • CymR, a repressor that binds to cumate operator sequences in the absence of cumate
  • SparQ Lentivector that contains an MCS to clone-in your gene-of-interest, the cumate inducible promoter with cumate operator sequences (CuO) upstream of the MCS, and one or more markers

CymR has a high binding affinity for cumate and, as more cumate is added, fewer CymR molecules bind to the CuO sequences in the promoter resulting in increased expression. Exhibiting much lower background expression than similar systems, SBI’s cumate-inducible vectors can provide up to 32-fold induction of gene expression.

Supporting Data

Tight expression control with low background with the SparQ Cumate Switch System

Figure 1. Get lower background and higher induction with the SparQ Cumate Switch System than other inducible systems.

Figure 2. Gene expression with the SparQ Cumate SwitchSystem can be turned on and off, then on again.

Figure 3. Gene expression with the SparQ Cumate Switch System is titratable, with increasing amounts of cumate inducing a linear increase in gene expression.

Figure 4. With the SparQ System, gene expression can also be titrated by increasing the amount of transduced SparQ lentivirus, even up to 30 MOI.
