How to find peptides, amino acids, or peptide synthesis reagents

This section contains links to resources that will allow you to search multiple companies at once to find the amino acid, peptide, or peptide synthesis reagent you need. If you cannot find your product from a link listed here, try our "peptide synthesis reagent suppliers" section.

If you wish to suggest or update a link, please email us. Also, please DO NOT email the Peptide Resource Page to buy a product. We are not a vendor or manufacturer. Thank you in advance.

1. There are several free online services that allow for multiple searching of companies when looking for peptides or peptide related reagents. These websites may cover less companies than the services listed below in section two, but they are more accessible.

  • AbCam - over 4000 peptides are available from their online catalog

  • BioSupplyNet - an on-line buyer's guide for researchers. Search by keyword entry or by searchable categories such as peptide synthesis reagents, peptide substrates, peptide analysis reagents, etc...

  • emolecules - a free, online, and searchable way to find a variety of commercially available chemicals, including amino acid derivatives, peptides, coupling reagents, etc... One can search the catalogs of 150+ suppliers by trivial name, trade name, CAS number, SMILES format, or structure. The result is a sortable list of structures, suppliers, product number, and various chemical properties. This website is recommended for its broad coverage and ease of use.

2. Many searchable chemical databases exist which will allow you to find a wide variety of chemicals, including amino acids, peptides, and peptide synthesis reagents. Typically, one can search based on structure, name, formula, supplier, etc... Unless indicated otherwise, these resources require the installation of proprietary (and sometimes costly) interface software dependent on an Oracle® or Windows® server database:

  • Available Chemicals Exchange (ACX) - offered by CambridgeSoft - a free, structure/name searchable, version that allows you to search 30 popular vendors. For more comprehensive searching (over 300 vendors), a subscription to ChemACX Pro, which allows access online or by CD, can be purchased here. The CD is also available as part of their Chemdraw Ultra software package.
  • Available Chemicals Database (ACD) - offered by MDL Information Systems - As part of the MDL ISIS suite of databases, ACD result lists can be saved, refined, and exported for use with other MDL applications or other custom uses. The database contains over 400,000 research grade and bulk chemicals.
  • DiscoveryGate (ACD) - a second way to access ACD offered by MDL Information System. Same as above but allows researchers to use ACD in a web-based environment using a browser interface.
