"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
Peptides are often used as tools in functional assays and antibody production, particularly in drug discovery. GenScript's peptide synthesis services include peptide synthesis, peptide modification, peptide library services, cGMP peptides, click peptide service, and recombinant peptide expression.
Our standard stepwise solid phase peptide synthesis (SPPS) procedures provide access to most peptides of between five and fifty amino acid residues. For long peptides of up to 200 amino acids, GenScript approaches synthesis by fragment condensation and native ligation techniques.
GenScript's secure and simple online quotation/ordering systems offer easy access to our peptide synthesis services, and our plethora of catalog peptides. In addition, GenScript offers the most competitive prices in the peptide synthesis industry.
GenScript's convenient peptide-antibody package delivers a one-stop streamlined service that produces peptide and antibody under one roof, relieving you from the inconvenience of finding another supplier for custom antibody services. The peptide-antibody package integrates GenScript's various mature technologies, such as OptimumAntigenTM design, peptide synthesis, peptide conjugation, immunization, affinity purification, and ELISA test.

1. High Success Rate:
GenScript surpasses many of its competitors in the rate of successful
peptide synthesis. Our success rate for custom peptide synthesis is
more than 95%, far higher than industry's general success rate 75%.
2. Microwave Technology:
GenScript has applied microwave technology to its peptide-manufacturing
pipeline. This technology increases chemical coupling efficiency and
contributes to our high success rate.
3. Free Peptide Antigen Design: GenScript's proprietary OptimumAntigenTM design tool combines the industry's most advanced algorithms with GenScript's time-tested expertise. It helps researchers to have protein sequences analyzed to select the best peptides for antibody production.
4. Secure Instant Online Quotations and Easy Online Ordering:
GenScript is the first company to offer an secure instant online quotation
system for custom peptides. GenScript also provides a secure and
convenient online ordering system for easy accesses to project status
tracking and data reports and our other products and services. Both
systems have been well received in the community.
5. Competitive Prices: Our peptide
service starts as low as $3.20/AA (€2.35/ AA). Every item on our
peptide service repertoire is at least 20% less expensive than its
counterpart from our competitors. In the European market, this figure
rises to 30% less expensive.
6. Fast Turnaround Time: GenScript
performs all tasks in-house. Our typical turnaround time is 2-3 weeks,
though this may vary depending on the size and complexity of the
project.
7. Convenient aliquoting on your demand: Conveniently packaging as little as 0.2 mg/vial allows researchers to use the amount of peptides as needed each time. The extra aliquots have better stability and can be used to test the solubility for your pilot experiment. This prevents unnecessary freeze-thaw cycles, water absorption and loss of reagent from self-allocating.
