About Thymosin Alpha-1 as a reference compound
Thymosin Alpha-1 is a 28-residue thymic peptide used as an immunological reference sequence in cytokine and T-cell assays. Every PureLabs lot is produced under GMP-aligned synthesis controls, filled and sealed in a controlled environment, then assayed by an independent partner laboratory using reverse-phase HPLC with mass-spectrometric confirmation. Material is released only at or above the stated 99.0% threshold; anything below it is rejected rather than sold. The certificate of analysis carries the chromatogram and MS trace for the exact lot you receive and stays archived under reference PL-1252 for the life of the batch. Available in 2 kit configurations, each containing ten vials.
Handling and storage
- Store sealed Thymosin Alpha-1 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 so the material never sees repeated freeze–thaw cycles.
Thymosin Alpha-1 — frequently asked questions
Common laboratory questions about sourcing, purity, storage and shipping of Thymosin Alpha-1.
What sizes of Thymosin Alpha-1 can I order?
Thymosin Alpha-1 ships in 2 configurations: 5 mg/vial · 10 vials/kit; 10 mg/vial · 10 vials/kit. Prices start at $105 per kit.
What purity is PureLabs Thymosin Alpha-1?
Current stock assays at 99.0% by reverse-phase HPLC with mass-spectrometric confirmation from an independent laboratory. Lots below the threshold never reach the catalog.
Does Thymosin Alpha-1 ship with a certificate of analysis?
Yes. A lot-specific certificate of analysis including the HPLC chromatogram and MS trace accompanies every order and remains retrievable under batch reference PL-1252.
How should Thymosin Alpha-1 be stored?
Sealed lyophilized Thymosin Alpha-1 is stable at −20 °C for at least 24 months. Once reconstituted, hold at 2–8 °C and use within about three weeks.
How quickly does Thymosin Alpha-1 ship?
Orders confirmed before 15:00 UTC dispatch the same working day in insulated, tracked packaging, subject to the import rules of the destination country.
Is Thymosin Alpha-1 sold for human use?
No. PureLabs supplies this material strictly as a reference compound for in-vitro and laboratory research. It is not a medicine and is not for human or veterinary consumption.
