Custom Peptide Synthesis

Bio-Synthesis is a leading global manufacturer of high quality custom-synthesized peptides. We have successfully synthesized tens of thousands of synthetic peptides for the biomedical research community, biotechnology and pharmaceutical companies and have consistently met the highest peptide standards of quality, service and technical expertise. As a peptide manufacturer, we also have the capability to perform a wide variety of synthetic peptide chemistries.

We routinely perform difficult custom peptide synthesis such as synthesis of long peptides (>136 mers), peptides containing unusual modifications, cyclic peptides, cosmetic peptides and peptide oligonucleotide conjugates. In addition, Bio-Synthesis has the capacity for large-scale synthesis (>1 kg) or custom GMP peptide production. Our facility is equipped with state-of-the-art peptide synthesizers and, coupled with our experienced peptide chemists, we are able to deliver your custom peptide synthesis products quickly and with high quality (purity of 90-95% is typical).

Each custom peptide synthesis project is carefully analyzed using an in-house, proprietary PEPscan Identifier and is carefully examined by our chemists. Final synthetic peptide products are shipped with detailed quality control documentation including an HPLC trace, Mass Spec, and a Certificate of Analysis. Custom peptide synthesis is carried out using an assortment of state-of-the-art instrumentation in our 20,000 square foot facility. As a custom peptide manufacturer since 1989, we have earned a reputation that speaks for itself. Our turnaround for custom peptide production is rapid. Most custom peptide orders are shipped within 1 to 2 weeks!

Because Bio-Synthesis maintains its own facilities located in Lewisville, Texas, we are able to provide comprehensive oversight to ensure the highest standards of quality. All custom peptides are accompanied with MS and HPLC analyses. Additional analytical data (e.g., sequencing, amino acid analysis) are available upon request.
