21st Century Biochemicals - guaranteed peptide fidelity

GMP peptide synthesis (and large scale peptide synthesis)

The development of peptides as drugs is increasingly attracting the attention of pharmaceutical companies. It is estimated that there are more than 40 marketed peptides worldwide and hundreds in some stage of pre-clinical or phased clinical development. The advantages of peptides as drugs include their high specificity, potency, and activity. For late stage research or clinical trials, it is not uncommon that multigram, even kilograms of high quality peptides are needed.

Here is a list of over 60 custom suppliers who produce peptides on the large scale (defined as > 1 gram). If a supplier can also produce the peptide under the guidelines of Good Manufacturing Practice, they are indicated with a "GMP". The largest quantity that a company states it can produce is indicated in parentheses. Please contact each company for additional information on their capacity and capabilities.

If you are interested in the custom peptide production on a small or research scale (i.e., < 1 gram), see our custom peptide suppliers page.

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