Peptide Array Service

Peptide Array Quotation

GenScript offers an extremely quick and cost-efficient custom peptide array service to assist in your drug development research. Based on our advanced peptide array platform, we can also provide comprehensive downstream services such as epitope mapping. If you need up to a milligram or more purified peptide (purity up to 95%) for epitope mapping, activity assays, or proteomic applications, view our rapid, high-throughput peptide library services.

For further efficiency and convenience, GenScript provides an instant online quotation system for peptide array services. In addition, GenScript provides six, free online peptide library/array design tools to help you generate different peptide arrays to assist your research design.

* Peptide Array Service is only available in countries or regions outside of the United States of America.
