Frequently asked questions
Scope of supply, documentation, specifications, testing and shipping — the questions we are asked most often.
12 common questions
What does “research use only” (RUO) mean?
All peptide products are supplied for research use only. They are not for human or veterinary use, and are not intended for therapeutic, diagnostic, cosmetic or injection applications. We supply to universities, research institutes, CROs and formulation developers for in-vitro and preclinical research workflows.
Do you supply peptides for human or therapeutic use?
No. Enquiries that fall outside research use are declined. The same scope of supply is stated on product pages, the COA and the shipping documentation.
What documents come with an order?
A batch-linked COA with method and pass/fail conclusion, the raw HPLC trace, the MS spectrum, MSDS and a packing list. NMR, amino acid analysis and endotoxin data are available on request.
What purity grades are available?
Crude, 95%, 98%, 99% and >99% by RP-HPLC are available for custom synthesis. For catalog RUO materials, purity and identity are confirmed against the batch COA rather than stated as a fixed catalogue grade — ask us for the current batch data before ordering. Desalted options are available where a project calls for them.
How much sample is needed for testing?
20 mg of lyophilized powder or 1 mL of solution per test. Special tests are confirmed case by case. Typical turnaround runs from 1–2 business days for Karl Fischer moisture to 3–14 days for sterility.
Are your test results accredited?
Testing is aligned with ISO/IEC 17025 (CNAS, ILAC-MRA) and CMA. Reports include the method, raw data and a pass/fail conclusion. Certificate details are available on request.
What is the minimum order quantity and lead time?
Both are quoted per project and depend on sequence length, modifications and batch size. Send us the sequence and specification and we return a quotation with a delivery schedule.
Which modifications can you synthesize?
Cyclic, phosphorylated, biotin- and FITC-labeled, PEGylated and disulfide-paired peptides, among others. Standard length is 5–60 amino acids; longer sequences are handled on request.
Which countries do you ship to?
We arrange shipping across North America, Europe, Asia-Pacific, the Middle East and Latin America. Express transit is typically 3–7 business days; see the international logistics page for reference times by market.
How is temperature-controlled material packed?
Sealed vials, foil pouches and desiccant, with cold-chain packaging using phase-change material and data loggers validated for 2–8 °C and -20 °C ranges. COA, packing list and MSDS travel with the goods.
Do I need an account to see the catalog and pricing?
The public catalog is open to everyone: all 49 active materials from our 88-item production database, with vial specifications and minimum order quantities, each on its own crawlable page. Wholesale prices are shown only to registered buyers — create a free account and sign in to see the three USD volume tiers and indicative order totals. You can also request a quotation without an account. An account additionally lets you place orders, track their status and keep your institution details on file. The remaining 39 materials are marked hidden in the source catalog and are not published.
How do I request a quote?
Use the quote form and include your sequence, purity grade, quantity and destination. We typically respond within 24 hours on business days.
