The Jump-In™ T-REx™ CHO-K1 Kit allows the targeted integration of genetic material into a specific pre-engineered R4 site in the Jump-In™ CHO-K1 cell line, to create an inducible isogenic stable cell line with less effort and in less time than traditional cell engineering methods. These cells stably express the tetracycline repressor protein, allowing for inducible expression of your retargeted gene of interest upon the addition of doxycycline.

The high retargeting efficiency, made possible by the R4 sites in the CHO-K1 cell line, allows the use of the isogenic pool for additional experiments without the need for clonal selection. Alternatively, the high retargeting efficiency allows for the easy selection of a positive stable clone expressing your gene of interest.

The Jump-In™ T-REx™ CHO-K1 Kit lets you:

• Quickly and efficiently develop stably engineered isogenic cell pools in about half the time compared to traditional cell engineering methods
• Inducibly express your gene of interest using doxycycline
• Utilize isogenic expression from a defined genomic locus as the ideal solution for comparative analysis of gene families, isoforms, or orthologs
• Generate multiple cell lines in parallel using the simplified work flow
• Easily access the technology without complicated licenses or restrictions to interpret

Save Time with Rapid and Efficient Generation of Engineered Cell Lines
With the Jump-In™ T-REx™ CHO-K1 Kit you can generate functional cell pools in as little as 2 weeks without laborious clone isolation and analysis, and the streamlined workflow makes it easier to generate several cell lines at the same time. Even generation of clonal cell lines can be done with reduced time and effort due to the high percentage of positive clones. In addition, the Jump-In™ technology gives you the freedom to generate an unlimited number of cell lines without restrictive licensing requirements.

Expand Your Experimental Capabilities
The Jump-In™ T-REx™ CHO-K1 Kit allows for inducible expression of your toxic or unstable gene of interest and is the ideal solution for targets and assays where transient engineering technologies are problematic. The kit also provides a convenient way to create target panels of gene families, isoforms, or orthologs. Genes coding for large proteins or multi-unit proteins are not a problem since the Gateway™ destination vectors accept large inserts.
