Each lot of Thymosin Alpha 1 is analyzed by HPLC to establish purity and checked for identity against its 28-residue acetylated sequence. The two measurements are recorded on a certificate of analysis identified by the batch number on the vial label, which becomes available from the support team once requested rather than accompanying every shipment automatically.
Thymosin Alpha 1 is supplied exclusively for research use (RUO) and is not intended for administration to humans or animals; it is not a drug, food, or cosmetic ingredient. Compliant handling, including appropriate biosafety measures and eventual disposal, is the responsibility of the receiving laboratory rather than of Eurolabs Peptides. As a thymic peptide, it is examined in the literature within immune cell modulation and in vitro immunology assays, referenced here as neutral scientific background rather than any statement of benefit.
To request the certificate of analysis, contact Eurolabs Peptides support and provide the batch number found on the vial label. The certificate covers the HPLC purity chromatogram and the identity result recorded for that specific lot.
Every batch is analyzed by an independent laboratory via HPLC before shipment. We document purity (avg. 99.41% in 2026), mass spectrometry identity, and sterility. Production follows GMP standards in ISO-certified laboratories.
Thymosin Alpha 1 is a 28-amino-acid thymic peptide, supplied here as a lyophilized reference reagent for laboratories conducting in vitro immunology research.
Thymosin Alpha 1 is manufactured to ≥99 % purity as verified by HPLC, with each production lot tested individually and documented in its own certificate of analysis.
Store the lyophilized vial refrigerated between 2 and 8 °C, protected from light, and use any reconstituted solution promptly rather than storing it long term.
Yes, a lot-specific certificate of analysis reporting HPLC purity and identity confirmation is available from support once the batch number on the vial label is provided.
