Suppliers of peptide synthesis reagents and peptides

Since Bruce Merrifield's first solid phase synthesis of a peptide, peptides have become readily available tools for the biologist, biochemist, and chemist. If you are involved in the synthesis of peptides or peptidomimetics, (click on the link for a great reference book), this webpage can guide you to suppliers of peptide synthesis reagents and starting materials.

If you are interested in pre-made peptides, you can also use this webpage to find vendors who sell biologically active peptides and peptide substrates. Please use these codes to find companies that sell the following reagents:

  • amino acids (AA or UAA) - divided up into two categories: naturally occurring amino acids (AA) or unnatural amino acids (UAA), usually protected with a protecting group suitable for Fmoc peptide synthesis. Unnatural amino acids include D-amino acids, alpha amino acids with non-natural side chains, beta amino acids, gamma amino acids, etc...

  • peptide synthesis reagents (reagents) - this category can include peptide coupling reagents (EDC, HBTU, HOBt, etc...) and peptide synthesis grade solvents

  • peptides (peptides) - includes bioactive peptides, antimicrobial peptides, and chromogenic/fluorogenic peptide substrates

  • resins (resins) - for solid phase peptide (SPPS) and organic synthesis (SPOS)

Peptide Fun Fact: The first synthetic peptide (Gly-Gly) was produced by Emil Fischer in 1901 using unprotected amino acids [Ber. Dtsch. Chem. Ges. 34 (1901) 2868].  With the development of N-protected amino acids and methods to activate them for amide bond formation, the complexity of synthesized peptide targets increased. In 1953 Vincent du Vigneaud completed the total synthesis of the cyclic peptide oxytocin [J. Am. Chem. Soc. 76 (1954) 3115]. This effort was undertaken to characterize the structure of this hormone and led to his winning of the 1955 Nobel Prize in Chemistry. Another significant synthetic milestone in the history of biologically active peptides was the total synthesis of the enzyme ribonuclease A in 1969 by Gutte and Merrifield [J. Am. Chem. Soc. 91 (1969) 501]. This 124 residue enzyme was produced via solid phase synthesis using Boc protected amino acids and dicyclohexy!carbodiimide (DCC) in an overall yield of 17%. The work of Fischer, Vignead, and Merrifield helped lay the groundwork for our current ability to produce pharmaceutically active peptides on the kilogram scale.
