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 peptide synthesis services. To meet various project demands, we offer standard, customized, and peptide library services with fast turnaround time of 2-3 weeks. With this service, we deliver the orders to all customers in San Diego area with $10 handling fee for existing sequencing customers and $15 handling fee for non-sequencing customers. For non-local US customers in other areas, we will deliver the orders via UPS Next Day Air Saver. Please note that the shipping and handling fees vary based on your location.

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.

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.
