As non-viral CRISPR gene insertion methods gain traction in advanced cell and gene therapy programs, GenScript offers industry-leading cGMP-compliant HDR template solutions to support your journey from research to clinical trials. Our clinical-grade GenExact™ single-stranded DNA (ssDNA), GenWand™ closed-end linear double-stranded DNA (dsDNA), and GenCircle™ circular dsDNA templates are engineered to meet the rigorous demands of CRISPR-based therapy development and IND-enabling studies.
Manufactured in state-of-the-art ISO Class 7 cleanrooms with ISO Class 5 isolators for aseptic processing, our cGMP facilities operate under a robust Quality Management System aligned with ICH Q7 guidelines for clinical use. GenScript’s cGMP HDR templates empower faster, more efficient progression from R&D to regulatory submission and clinical manufacturing.
Full regulatory documentation provided, including CoAs and quality certificates, to support IND submissions and clinical trial readiness.
Non-viral HDR templates enable safer, faster CRISPR cell engineering by eliminating reliance on traditional viral vectors.
We offer RUO, INDEdit, and cGMP reagents to support every stage of CRISPR therapy development.
Fully customizable format, sequence, and scale:
Manufactured under ICH Q7-compliant cGMP conditions with validated QC for purity, sterility, stability, and more.

"We were very happy to partner with Genscript on critical experiments demonstrating
high efficiency and yield of CAR knock-in cells at clinical scale. The long ssDNA produced by
Genscript exceeded our expectations and helped us clearly demonstrate the potential for future
therapeutic applications using these methods.“

BRL Medicine Inc.,
On November 5, 2024, BRL Medicine Inc. announced that its developed "Targeted
CD19 Non-Viral PD1 Site-Specific Integration CAR-T Cell Injection" (BRL-203) has officially
received Investigational New Drug (IND) approval from China National Medical Products
Administration (NMPA) for the clinical treatment of "moderate to severe refractory systemic
lupus erythematosus (SLE).“
GenScript provided core materials, GMP sgRNA, and gene knock-in templates (dsDNA) for this approved
non-viral CAR-T therapy. This contributes to the development of safer, more efficient, and
cost-effective cell therapies based on CRISPR technology and supports the treatment of a more diverse
range of diseases.
