Alternative Peptide Synthesis sources

In light of the decreased demand for and increasing subsidy required to run the peptide synthesis service, the University is sunsetting the peptide synthesis service from the Proteomics Resource Center (PRC), effective December 30, 2020.   If you have questions about the decision to sunset this service, please contact Amy Wilkerson.

The PRC has compiled a list of proven commercial sources for custum peptide synthesis requests. Additional advice regarding vendors is available from Purchasing.
