CRISPR non-viral gene insertion methods have gained popularity among researchers. GenScript, as the leading provider of non-viral HDR template solutions, now offers cGMP GenExact™ single-stranded DNA (ssDNA) and GenWand™ closed-end linear double-stranded DNA (dsDNA) services, and GenCircle™ miniaturized circular dsDNA services. These services will enable newer gene and cell therapy R&D programs to advance to IND filing and clinical trials faster and more efficiently.

GenScript’s cGMP manufacturing lines are located in ISO Class 7 cleanrooms, and include ISO Class 5 isolators for aseptic processing operation. The cGMP manufacturing lines operate a Quality Management System that meets the requirements for APIs for use in clinical trials as defined by ICH Q7 Good Manufacturing Practice for Active Pharmaceutical Ingredients, Section 19.
