Beyond typical HDR donor DNA design, we also offer Cas9 Targeting Sequence (CTS) added ssDNA and dsDNA design for improved gene knock-in efficiency. CTS allows for the co-delivery of donor DNA and sgRNA/Cas9 complex into the nucleus target gene site, therefore increasing HDR rate. In our collaboration with Dr. Marson at Gladstone and UCSF2, GenExact™ ssDNA with CTS design (delivered via electroporation) consistently outperformed in-house generated HDR templates, showing lower levels of toxicity and knock-in efficiency of 46.2% at a GMP-compatible scale. More info for CTS design can be found in this paper.

Find Your Kit!
Choose your desired gene target:
- TRAC – Mostly commonly used site for new CAR insertion in T cells, our sgRNA is designed to target the first exon on the TRAC locus
- Rab11a – Housekeeping gene for more general insertion optimization
- Other Gene Target – Check out our customized sgRNA and ssDNA/dsDNA Services
Which Cas9 species would you be using?
- Wild type Cas9 protein – The research standard for gene editing with one N-terminal nuclear localization signal (NLS).
- Enhanced specificity SpCas9 (eSpCas9)-2NLS protein – SpCas9 (K848A/K1003A/R1060A) is structurally engineered with double-ended nuclear localization signals (NLSs) for improved target specificity by Feng Zhang Laboratory at the Broad Institute1. eSpCas9 is able to reduce off-target effects by over 10-fold, while maintaining robust on-target genome editing efficiency.
Select your donor template format:
- GenExact™ ssDNA and GenWand™ dsDNA
- GenExact™ ssDNA only
- GenWand™ dsDNA only
Do you want to test Cas9 Targeting Sequence (CTS)2 for improved knock-in efficiency in your design?
- Yes – Selecting this will add donor templates with CTS design to your test kits, as well as corresponding oligo for the CTS annealing
- No
Note: Based on our optimized protocol, material in each item labeled for 12 RXN should be enough to cover 12 reactions using Lonza 4D system or 25 reactions using Neon System. Please check your electroporation protocol and ensure enough quantity is added for each item.
