CompoZr Targeted Integration Kits

Now Available! Targeted Integration into the Rat Genome at the Rosa26 Locus

CompoZr Targeted Integration Kits are designed to rapidly integrate a user-specified gene of interest (GOI) into preferred sites of integration in either the human, mouse or rat genome. In the human genome the adeno-associated virus (AAVS1) locus on human chromosome 19 is the preferred site, while the Rosa26 locus is located on chromosome 6 in the mouse and chromosome 4 in the rat. The well characterized Zinc Finger Nucleases (ZFNs) in these kits target each site with high specificity, creating a double strand break. ZFN treated cells then use a pZDonor plasmid with homology arms to either the AAVS1 or Rosa26 genomic regions to replace the natural locus by the repair process of homology directed repair. The pZDonor plasmid can be engineered to contain your GOI and will direct targeted integration of your GOI into the AAVS1 or Rosa26 loci. CompoZr Targeted Integration Kits provide a common integration site within a defined locus to generate stable, uniform gene expression levels.

Benefits

Effective Integration Efficiency

  • Any human, mouse or rat cell type can be modified with CompoZr Targeted Integration Kits
  • Targeted Integration Kit ZFNs are well-validated pairs that cleave the target DNA with high specificity
  • ZFN mediated targeted integration can be achieved with high success rates

No Transgene Landing Pads Required

  • Prior to ZFN transfection cell lines don’t require engineering of transgene landing pads
  • Lack of need for transgene landing pads enables immediate transfection of cell lines with GOI

Rapid Biallelic Integrations with a Single Transfection

  • Monoallelic and biallelic integrations have been generated with ZFNs
  • Gene integrations can occur in as little as 48 hours

Flexibility of Use

  • Expression may be driven by the endogenous promoter or by inserting your promoter of choice
  • Puromycin selection is available with the Targeted Integration Kit – AAVS1

Schematic of the CompoZr Targeted Integration Kits

CompoZr Targeted Integration Kits Schematic

A. Your Gene of Interest construct (GOI) is subcloned into the supplied pZDonor plasmid at the multiple cloning site (MCS). The GOI construct consists of any promoter of your choice, the gene and the polyA sequence. The MCS is flanked by left and right homology arms to the genomic integration site.
B. The modified pZDonor now contains your GOI between the homology arms.
C. The modified pZDonor and supplied mRNA, encoding ZFNs that target the genomic integration site of are co-transfected into the cell line of your choice.
D. The ZFNs bind and cut the target site in the nucleus, creating a double strand break. The cell uses the modified pZDonor plasmid as a repair template.
E. ZFN stimulated homology-directed repair leads to targeted integration of your gene construct into the genomic locus in the cell line of your choice. Your gene can be transcribed either through the endogenous promoter or by inserting a promoter of your choice upstream of the GOI.
F. Single cell cloning is used to isolate clones with targeted integration into the target locus.
