Standard Chemical Peptide Synthesis Service
GenScript produces the highest-quality peptides with a success rate well above the industry standard. GenScript's FlexPeptideTM technology results in significant cost saving by increasing chemical coupling efficiency and shortening coupling time.

GenScript's FlexPeptideTM technology includes:

  1. Flexible choices of Liquid Phase Peptide Synthesis (LPPS), particularly for shorter peptides, or Large-Scale Solid Phase Peptide Synthesis (SPPS) suited to longer, more complex sequences.
  2. Microwave technologies that increase reaction rate and improve peptide yields.
  3. Proprietary ligation technology that allows joining peptides of up to 200 amino acids.

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!

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. Secure Instant Online Quotations and Easy Online Ordering: GenScript is the first company to offer a 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.

4. Competitive Prices: Our peptide service starts as low as $3.20 per amino acid. 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.

5. 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.

6. 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.
