GenScript provides high-quality peptide synthesis service with a 95% success rate, which is well above the industry standard of 75%. We are committed to Total Quality Management (TQM) to ensure our customers' complete satisfaction. TQM includes MS and HPLC analyses performed after the completion of peptide synthesis, purification, and QC (quality control) steps. These analyses are followed by independent QA (quality assurance) procedures, which double guarantee the highest quality possible for every delivered peptide.
Peptide Synthesis Capacity and Capability
Our custom peptides are synthesized in a 20,000 square foot state-of-the-art facility with peptide synthesizers, HPLCs, and mass spectrometers capable of producing over 6000 peptides per month. Other features of our capacity and capability include:
As one of the pioneers of the life science research peptide service industry, GenScript aggressively seeks to develop new technologies. We have a passion for innovation!
GenScript's FlexPeptide™ technology increases chemical coupling efficiency and shortens coupling time, which allows us to offer economical peptide synthesis services to you. The FlexPeptide™ technology platform combines the following technologies:
GenScript's peptide synthesis is competitively priced, starting at $3.2/AA. Customers retain all rights to the sequence data and related intellectual property.
Every step of peptide synthesis is subject to GenScript's stringent quality control. Typical delivery specifications include:
TFA Removal Service:
TFA is often used in the final cleavage of custom peptides from the solid support after solid phase synthesis. Hence, TFA may be left behind in the final peptide preparation, even after purification. Trace amounts of TFA can cause cytotoxicity in cell culture assays.
Hydrophobic peptides are often insoluble or have a propensity to aggregate. Using improper conditions for dissolution of these peptides can result in the loss of peptides.
Peptide Content Analysis:
Custom peptides are delivered as a gross peptide preparation consisting of a mixture of the target peptide, peptidic impurities, counter ions, and water. A peptide content analysis determines the precise amount of target peptide in the gross peptide preparation. Exact quantification of your peptide can increase experimental accuracy and consistency between different batches of peptide.
Complimentary ArgonShield™ packaging:
Peptides containing Cys, Trp, or Met are susceptible to oxidation, while peptides with multiple charged residues (e.g. Asp, Glu, Lys, Arg or His) are at risk for deliquescence. To protect the activity of your custom peptides, all synthesized peptides are sealed in argon gas-filled vials to prevent oxidization and deliquescence, at no cost to you.
Complimentary aliquoting service:
Repeated freeze-thaw cycles can damage your custom peptides. GenScript provides aliquoting services (free for the first 5 vials) for all customer peptide orders.
Since 2004, GenScript's Peptide Synthesis Services have helped thousands of scientists publish their research in peer-reviewed journals like Science, Nature, Cell, and PNAS.
"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, SwedenMore publications
