21st Century Biochemicals - guaranteed peptide fidelity

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 the following codes to find companies that sell the above-mentioned 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)

If you would like to have your company added to the list or update/correct any information, please email us.
