GenWand™ Double-Stranded DNA (dsDNA) service for T-cell engineering

GenScript USA Inc., a global leader in life science research tools and services, recently announced the launch of the GenWand™ Double-Stranded DNA (dsDNA) service for the production of CRISPR knock-in homology-directed repair (HDR) templates in T cell engineering.

Closed-end dsDNA allows researchers to conduct gene knock-in with greater efficiency and lower toxicity than conventional PCR methods and is the perfect solution for large-scale screening and scale-up in cell and gene therapy.

We continue to believe that non-viral vector delivery has clear advantages - including safety - in CRISPR/Cas applications for gene and cell therapy. Our GenWand closed-end DNA service offers better performance and scalability to researchers, and represents an important expansion of our portfolio of services for gene and cell therapy."

Ray Chen, PhD, President, Life Science Group, GenScript

GenScript's GenWand dsDNA service produces covalently closed-end linear DNA to help enhance dsDNA stability by restricting digestion of the dsDNA by endonucleases once entering cells. It also reduces the risk of non-homologous end joining and boosts the accuracy of knock-in when applying CRISPR homology-directed repair machinery.

Manufactured using a proprietary production process, GenScript's dsDNA is available in 2-10 kb sequences from micrograms to grams. Varying grade qualities are available from research grade to basic GMP.

This new service complements an expanding portfolio of offerings for CRISPR/Cas genome editing, including the GenExact™ ssDNA Service and Phase Appropriate GMPsgRNA through its CRISPR Synthetic Guide RNA Services.

In collaboration with the University of California, San Francisco, GenScript has helped deliver around 2.3 Kb ssDNA for T cell engineering with non-viral genome targeting utilizing long DNA sequences.

Each year the company produces over 10,000 sgRNA, which it delivers to clients around the world. GenScript has also manufactured over 30 phase-appropriate GMP sgRNA batches for biopharma clients in China.

As a global leader in gene synthesis, GenScript is committed to offering a one-stop-shop to customers developing new immunotherapies to fight cancer. "We are continually expanding our portfolio of innovative new products and services in this field and expect to support additional projects at the basic GMP level for investigational new drug applications and early-stage clinical trials."
