Customer Testimonials

"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.

"GenScript has been our go-to provider for the lab's gene synthesis needs. The constructs are always on-time (or early), always high quality, and the customer service excellent. I especially appreciate the fast turnaround time on quotes and pricing inquiries."
Samuel H. Sternberg, Ph.D., Columbia University
"I always chose to do gene synthesis and subcloning with Genscript because they are very reliable."
Kevin Truong, University of Toronto.

"GenScript have provided us with a first-rate service. Their customer service has been remarkable. They work on my long gene synthesis projects, and the quality of the gene synthesis is outstanding. Looking forward to working with the team on future projects."
Simon Anthony, Ph.D., Columbia University Medical Center
"I have been using GenScript gene synthesis since 2017. I am very impressed with their excellent, prompt and quality services, which is always on time and even ahead of time for every order."
Chester Li, PhD, Neoletix Lab. Inc

"We repeatedly ordered synthetic genes from GenScript. In any case, the synthesis was exceptionally fast (usually within 7-10 business days), convenient, reliable and cost-effective. Customer service was exceptionally friendly and even approachable over Christmas vacation. For that reason, we can only recommend this service to any customer – wherever they may be located."
Dr. Tilmann Bürckstümmer, Austrian Academy of Sciences, Austria
