Peptide Synthesis Service Description

Synthetic peptide plays a critical role in many research and development projects across various areas of scientific disciplines. Peptide applications range from T-cell stimulation to epitope mapping, enzyme-substrate studies, and much more!

Other than DNA sequencing services, Eton Bioscience is pleased to provide you with high quality peptides synthesized by state-of-the art peptide synthesizer. To meet various project demands, we offer standard, cGMP, customized, and peptide library services with fast turnaround time delivered to you within 2-3 weeks, and to show our commitment and appreciation to our customers, we deliver the orders to all customers in San Diego and Raleigh/Durham/RTP area free of charge. For customers in other areas, if you are using our DNA sequencing services, the shipping is also free. For non-DNA-sequencing customers, we will charge a flat shipping and handling fee of $15 for standard Fedex overnight service.

Certification of Analysis

Your Quality Assurance

HPLC

All peptides synthesized will be purified using a new HPLC system with fraction collection capability. The purity of your peptide will be authenticated by a comprehensive HPLC data report.

HPLC

MS

To confirm the identity of the synthesized peptide, we use a state-of-the-art Mass-Mass Spectrometer system to determine the exact molecular weight of the peptide. A detail Mass Spec report will be included with the peptide products.

MS

We provide custom peptide amino acid analysis for all peptide orders. The example shown to the right displays peptide sequence, charge, molecular weight, hydrophilicity, isoelectric point, and suggested solvents for your peptide products.

MS

Delivery

Standard service

Upon delivery, you will receive:

  1. Lyophilized peptide
  2. HPLC data report
  3. MS data report
  4. Peptide Analysis

Service Commitment

Most peptides shall be delivered within 2 to 3 weeks from the order date. All effort will be made to deliver your order at an earlier time. For local customers at San Diego and Raliegh/Durham/RTP, we will be able to deliver the peptides to you personally free of charge. For existing DNA sequencing customers, the shipping is also free. For non-DNA-sequencing customers, we will charge a flat shipping and handling fee of $15 for standard Fedex overnight services.
