PepPower® Peptide Synthesis Technology
GenScript's proprietary PepPower® peptide synthesis technology platform integrates automated peptide synthesizers, state-of-the-art microwave technology, and ligation technics. PepPower® platform allows us to flexibly choose in between Liquid Phase Peptide Synthesis (LPPS) or Large-Scale Solid Phase Peptide Synthesis (SPPS) base on your requests. With the assistance of microwave technology, we are capable of increasing chemical coupling efficiency and reducing synthesis time by 75% on average. In addition, our proprietary ligation technology allows for the synthesis of peptides up to 200 amino acids with high efficiency and accuracy. With PepPower® platform, we are able to synthesize reliable peptides faster and help you obtain consistent results sooner.

Customer Testimonials
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.
Robert Bao, Principal Investigator, PACT Pharma Inc., 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. Guo Luo, Postdoctoral Research Fellow, Stanford University School of Medicine, USA
"I have been using the peptides from your company since 2004. The high quality standard and competitive price of your company will keep us hooked, hopefully for the years to come."
Dr. Miguel Morales, Universidad de Barcelona, Spain
"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."
Dr. Steven Applequist, Karolinska University Hospital, Sweden
