Gene Synthesis Service
As a pioneer and leader in gene synthesis technology with over 600,000 completed gene synthesis projects for scientists around the world, GenScript has the expertise to help you achieve your gene synthesis needs. Gene synthesis enables powerful solutions for molecular cloning, creating fusion proteins, or achieving sufficiently high protein expression levels. Compared to traditional molecular cloning techniques, GenScript's gene synthesis service saves both time and money while offering unparalleled top to bottom customizability.
Our experienced Ph.D.-level project managers ensure that you receive professional service tailored to your needs and on-time delivery of ISO 9001:2008 certifiedwhat's this? products with 100% sequence accuracy guaranteed.
"GenScript is the company that I have entrusted my project with. The delivery of your gene synthesis is on time and the OptimumGene™ technology on your Gene-on-Demand® gene synthesis platform has increased my gene expression dramatically. I am very happy with my results and GenScript is always my first choice for gene services." – Bin He, Bristol-Myers Squibb, USA.
The International Organization of Standardization, (ISO) defines quality management standards across industries and national borders. ISO 9001 is a series of documents that establish requirements for Quality Management System (QMS) standards. ISO 9001 certification assures customers that the company has a reliable QMS in place. An organization with an effective QMS will meet customer expectations with greater regularity and precision than an organization that does not.
GenScript's products and services are certified by ISO 9001:2008, the current and only valid version of the QMS standard.
