While a large part of the SARS-CoV-2 virus is made up of proteins, smaller fragments of these proteins are of equal interest. New England Peptide and Peptides International have over 50 years combined company experience in peptide synthesis and can aid in your research. Here are some of the ways we can aid in your research with custom peptide synthesis of:

  • HLA-A*0201-Restricted Peptide Epitopes
  • HLA-A*2402-Binding Peptides
  • SARS-CoV-2 Nucleocapsid Fragments
  • T-cell and B-cell Epitopes of SARS-CoV-2
  • Furin Substrates and Inhibitors
  • Fusion Inhibitors Targeting HR1 Domain of the SARS-CoV-2 Spike Proteins
  • Substrates and Inhibitors of SARS-CoV-2 Mpro/3CLpro/C30 Endopeptidase
  • Peptide Adjuvants like Toll-Like Receptor 4 (TLR-4) Agonist Peptides (example: Ala-Pro-Pro-His-Ala-Leu-Ser)
  • ACE2 Inhibitors and Substrates
  • AT2 Receptor Agonists and Antagonists
  • TMPRSS2 Substrates and Inhibitors

If you have need of any other custom peptide synthesis, please visit:

Antibodies to Spike protein or ACE2 may also block important binding interactions and prevent infection. For more information on Custom Antibody development, please visit:

In addition, we also carry, from our catalog, related proteins (including the Nucleocapsid, S proteins), ACE2 substrates, protease inhibitors and more. Our COVID-19 Information Station is a convenient place for all of our updated news and related products. We wish you luck in your research endeavors, and most of all good health!
