"We use GenScript custom gene and peptide synthesis services for about 15 years. It is afordable and reliable way to speed-up our research. I did not have any problems with GenScript and plan to use their other services in my work."
Reyhan Muhammadn
Institute Cancer Research
"We are really satisfied with GenScript's Peptide Synthesis service, especially for its excellent peptide quality and prompt delivery. GenScript's service was instrumental in our recent publication, Spatial Control of the APC/C Ensures the Rapid Degradation of Cyclin B1, where obtaining a high-resolution structure quickly was essential. I believe GenScript played a crucial role in our success."
Mehdi Alikhani
University of Notre Dame
"We frequently order synthetic peptides from GenScript for our LC/MS MRM experiments. I am thoroughly satisfied with their service, competitive pricing, product quality, and the daily updates on the status of our order."
RachelRock
University of California, San Francisco (UCSF)
"I discovered GenScript when searching for a company to use for peptide synthesis because ordering the already synthesized peptide from a supplier was rather expensive. I was thrilled to discover GenScript's peptide synthesis service which allowed me to generate the peptide with the quality parameters exactly to my liking, aliqouted to my liking, and for under half the price of buying it pre-synthesized!! The peptide worked in my disease model just as well as the presynthesized peptide."

"GenScript's services, including Gene Synthesis, Peptide Synthesis, and Antibody Production, have proven invaluable to my research. Their services are always of the Highest Quality with Reliable turnaround times. "
Augustine Choy
Regeneron
"I primarily use GenScript for peptide synthesis and gene synthesis. they are always a pleasure to work with from simple orders to complex orders where they took the time to learn about my project and help design my constructs. They have always provided high-quality reagents in a timely manner. always my first go-to supplier for these services!"

Yuwan Guo
University of Pennsylvania
"GenScript is our lab's go-to vendor when it comes to peptide synthesis. The GenScript team has always been quick in email communication and sometimes to go over technical details over the phone. We've also compared the pricing of peptide synthesis with many other vendors and GenScript has always come back as the best price. We will definitely keep using GenScript with peptide synthesis in the future!
Robert Bao
Principal Investigator, PACT Pharma Inc., USA
"GenScript peptide synthesis gives us amazingly fast turnaround time and very competitive prices. Their peptide quality has been excellent. Our experience with them has been so positive that we have essentially shut down our internal peptide synthesis efforts and now use them for all of our custom peptides."
Dr. Guo Luo
Stanford University School of Medicine, USA
"I have ordered thousands of peptides with different length at GenScript, including modified forms. Both high quality and competitive price of each make GenScript our first choice."
Dr. Steven Applequist
Karolinska University Hospital, Sweden
"Although I order infrequently I do appreciate the customer service, approx 2-week turnaround time, and rapid delivery to my location. Price is average or slightly lower than average. I have had opportunities to order from other companies at discounts but do not due to concerns about quality. I can depend on GenScript quality."
