About PT-141 as a reference compound
PT-141 is a cyclic heptapeptide melanocortin analogue supplied as a characterised reference ligand for receptor-binding work. Every PureLabs lot of PT-141 is produced under GMP-aligned synthesis controls, assayed by an independent partner laboratory using reverse-phase HPLC with mass-spectrometric confirmation, and released only above the stated purity threshold of 99.0%. The certificate of analysis is lot-specific, carries the chromatogram and MS trace for the exact vial you receive, and stays archived under reference SEQ-1138 for as long as the batch exists.
Handling and storage
- Store sealed PT-141 vials at −20 °C, protected from light.
- Reconstitute with bacteriostatic or sterile water added slowly down the vial wall; swirl, never shake.
- Hold reconstituted solution at 2–8 °C and use within roughly 21 days.
- Aliquot before freezing to avoid repeated freeze–thaw cycles.
PT-141 — frequently asked questions
Common laboratory questions about sourcing, purity, storage and shipping of PT-141.
What purity is PureLabs PT-141?
Current stock assays at 99.0% by reverse-phase HPLC, confirmed by mass spectrometry at an independent laboratory. Any lot testing below the threshold is rejected rather than sold.
Does PT-141 ship with a certificate of analysis?
Yes. A lot-specific certificate of analysis including the HPLC chromatogram and MS trace accompanies every PT-141 order and remains retrievable under batch reference SEQ-1138.
How should PT-141 be stored?
Sealed lyophilized PT-141 is stable at −20 °C for at least 24 months; once reconstituted, hold at 2–8 °C and use within about three weeks.
How fast does PT-141 ship?
Orders confirmed before 15:00 UTC dispatch the same working day in insulated, tracked cold-chain packaging, subject to the import rules of the destination country.
Is PT-141 sold for human use?
No. PureLabs supplies this compound strictly as reference material for in-vitro and laboratory research. It is not a medicine and is not for human or veterinary consumption.
