Quality and Technical Analysis

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 1984, 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.
