Lab FAQs
Straight answers on how our peptides are made and tested, what research-use supply means for your laboratory, and how lots, records and shipments are controlled. Back to the laboratory overview
Research use & eligibility
What the research-use terms require of you, and what we can and cannot provide.
- What does research use only mean in practice?
- Every vial is supplied for in-vitro laboratory research and development only. The material is not a drug, supplement, food, cosmetic or medical device, it has not been evaluated by any regulator for safety or efficacy, and it is not intended to diagnose, treat, cure or prevent any condition in humans or animals. Administration to people or animals is prohibited and voids all warranties and return rights.
- Who is eligible to order?
- Orders are accepted from researchers, laboratories, universities and commercial research organizations with the training, facilities and waste-handling capability to work with research compounds. Buyers attest at site entry that they are at least 21 years old and are acquiring material for laboratory research only. We may request institutional details before releasing an order.
- Can I resell, relabel or repackage material?
- No. Material is released to the named purchaser for their own research. Reselling, relabeling, repackaging, compounding or transferring material for administration is a breach of the research-use terms and ends the account.
- What documentation comes with an order?
- Each order includes a compliance pack: the order summary, a Certificate of Analysis for every lot shipped, the laboratory certifications behind those assays, handling and storage instructions, and the research-use notice. The pack is linked from the confirmation email and downloadable as a PDF from the order status page.
- Do you provide dosing or protocol advice?
- No. We publish analytical data, solubility and storage information only. We cannot recommend concentrations, schedules or experimental designs, and no member of our team may advise on use in humans or animals.
Synthesis & analytical testing
How material is assembled, purified and assayed before a lot is released.
- How is the material synthesized?
- Peptides are produced by solid-phase peptide synthesis (SPPS) using Fmoc chemistry, assembled residue by residue on resin, then cleaved, purified by preparative reverse-phase HPLC, lyophilized and filled into sealed vials under controlled conditions.
- How is purity measured and what is the release floor?
- Purity is measured by reverse-phase HPLC with UV detection against a 98.5% area floor. Lots that fall below the floor are rejected rather than reworked into catalog stock. The chromatogram for your lot is retained with the batch record and summarized on the Certificate of Analysis.
- How is identity confirmed?
- Identity is confirmed by mass spectrometry: the observed molecular weight must conform to the theoretical mass for the stated sequence within the method tolerance. Sequence-level confirmation is performed when a compound or a deviation warrants it.
- What else is tested before release?
- Residual moisture is measured by Karl Fischer titration on the lyophilized cake, endotoxin is screened by LAL, and each vial is visually inspected for a white to off-white cake, an intact seal and legible lot marking.
- Why do vials sometimes look different between lots?
- Lyophilized cake appearance varies with fill volume, peptide sequence and the freeze-drying cycle. A flat, shrunken or partially collapsed cake is a physical characteristic, not a purity result — the Certificate of Analysis for the lot is the authoritative record.
- How should vials be stored and reconstituted?
- Keep unopened lyophilized vials at 2–8 °C short term or −20 °C for long-term storage, protected from light. Bring the vial to room temperature before adding diluent, direct the diluent down the vial wall instead of shaking, then label the reconstituted vial with compound, concentration, lot and date and refrigerate it. Avoid repeated freeze-thaw cycles.
Laboratory compliance & handling
Standards, record retention, shipping controls and waste handling.
- What standards does the supply chain work to?
- Synthesis and fill take place in audited partner facilities following current good manufacturing practice appropriate to research-grade materials, and analytical work is performed by a third-party laboratory operating under an ISO/IEC 17025 quality system. Certificates and audit dates for the current program are published on the laboratory page.
- How long are records retained?
- Batch records, analytical raw data and release decisions are retained for a minimum of five years and are traceable from the lot number printed on your vial.
- Does a Certificate of Analysis mean the material is approved or safe?
- No. A COA reports what was measured — purity, identity, moisture, endotoxin — for a specific lot. It is not a safety determination and carries no regulatory approval of any kind.
- How is material shipped?
- Released inventory is held in monitored freezers and shipped with cold packs and tracked delivery. Once a carrier and tracking number are assigned, your order status page shows the carrier and a live tracking link.
- How should unused material and sharps be disposed of?
- Route unused powder, reconstituted solutions, contaminated consumables and sharps through your institution's chemical and biological waste streams in line with local regulations. Never place research material in general refuse or down a drain.
- What happens if a lot fails a check after release?
- We hold remaining stock, notify affected purchasers by email with the lot number and the finding, and provide replacement or credit. Records of the hold and the decision are retained with the batch file.
