    What to Include in a Quote Request

    The more complete your request, the faster we can return firm pricing. A quote can normally be priced from the following details alone:

    • Sequence in single-letter or three-letter code, including any D-amino acids or unnatural residues
    • Terminal modifications such as N-terminal acetylation or C-terminal amidation
    • Other modifications — cyclization or disulfide bridges, PEGylation, lipidation, biotin or fluorescent labels, phosphorylation
    • Quantity per peptide and the number of distinct peptides
    • Purity target — commonly >95% or >98% by HPLC
    • Analytics required — HPLC and MS are standard; specify if you need additional testing or a net peptide content assay
    • Format — lyophilized powder, salt form preference, aliquot size, and vial count
    • Timeline and any date the material is needed by

    Custom Synthesis FAQs

    How fast will I receive a quote?

    Quote requests submitted during business hours are typically answered the same day, and always within one business day. Emails to our support team are usually answered within 10 minutes, Monday through Saturday, 8:00 AM to 10:00 PM EST.

    What are typical turnaround times?

    Standard synthesis runs about 3 to 4 weeks from approval, expedited about 2 weeks, and rush roughly 1 week. Short unmodified sequences fall at the fast end of those ranges; long, cyclized, or heavily modified peptides can take longer and we will confirm the schedule in writing with your quote.

    What sequence lengths and modifications can you handle?

    Routine work covers sequences up to roughly 50 residues, with support for D-amino acids, terminal capping, disulfide bridges and cyclization, PEGylation, lipidation, and labeling. Longer or unusually difficult sequences are reviewed case by case before we quote them.

    What documentation comes with a custom order?

    Every custom lot ships with a Certificate of Analysis including HPLC purity and mass spectrometry identity confirmation. Additional analytics, such as net peptide content, can be added on request when you request your quote.

    Is there a minimum order?

    Custom synthesis is priced per project rather than by a fixed minimum. Very small research quantities are viable, though cost per milligram drops substantially at larger scales, so it is worth asking for pricing at more than one quantity.

    Is my sequence kept confidential?

    Yes. Sequences submitted for quoting are treated as confidential, are used only to price and produce your order, and are never added to our catalog. We can execute an NDA before you send sequence details if your organization requires one.
