Companies that offer custom peptide synthesis

Bruce Merrifield's original synthesis of peptides attached protected amino acids to a growing chain that was covalently bonded to a resin. That unheard of method to synthesize peptides not only won him the Nobel Prize in Chemistry in 1984, but also ushered in a new era of peptide research - scientists were now able to design their own peptides and study them at a previously unattainable scale. Nowadays, you can still do it yourself (see our section on peptide synthesis reagents) or you can order them from a variety of companies as single purified entities, in the form of libraries, optimized for anti-peptide antibody production (MAPS), or even recombinantly produced.

Search our lists of over 110 custom peptide suppliers with a brief categorization of the kind of services that they provide. To access our second page of such companies (H-Z) click here. Please note the meaning of the following descriptors:

  • custom - small scale (typically < 1 gram) synthesis of peptides containing the standard 20 amino acids

  • modified - small scale (typically < 1 gram) synthesis of modified peptides (e.g. N-acetylated, C-amidated, biotinylated, etc.) or peptides containing unusual or unnatural amino acids (e.g., phosphotyrosine, D-amino acids, beta-amino acids, etc...). Please note that each company has its own list of modifications it can incorporate. As a result, you will have to check with the individual company to see what they can do.

  • library - able to produce peptide libraries or peptide arrays for screening purposes - check with the company for the format and degree of purity

  • MAPs - able to produce multiple antigenic peptides (MAPs)

If you are interested regulatory compliant production of GMP peptides (or large scale (> 1 gram) peptide synthesis, non-GMP), see our page on GMP peptide manufacturers.

Peptide Fun Fact: The Fmoc group is the most common amino acid protecting group using today in the solid phase synthesis of peptides.  However, the use of this group is relatively new in the history of peptide synthesis.  Peptides were originally produced more laboriously in solution where a strategy of amine protection followed by coupling then amine deprotection had to be followed.  Developed by Bergman and Zervas in 1932 [Ber. Dtsch. Chem. Ges. 65 (1932) 1192], the Cbz group was the first amine protecting group to be used and was removed using catalytic hydrogenolysis.  The acid labile Boc group was developed by Carpino in 1957 [J. Am. Chem. Soc. 79 (1957) 98] and was the second popular protection strategy to produce peptides in solution.  The use of the fluorenylmethoxycarbonyl (Fmoc) group, also invented by Carpino [J. Am. Chem. Soc. 92 (1970) 5748], became popular in the 1980s because of its use on automated peptide synthesizers.
