Thymosin Alpha-1, also written as Tα1 and known under the international non-proprietary name thymalfasin, is a linear 28-amino-acid peptide first isolated from thymus tissue. Its empirical formula is C129H215N33O55 with a molecular weight of 3108.28 g/mol.
In controlled laboratory environments, Thymosin Alpha-1 is investigated in connection with thymic peptide signalling, T-cell maturation models, cytokine assays, toll-like receptor pathways and experimental host-response systems.
Full research description
Published research concerning thymic peptides, immune signalling or antiviral models is predominantly preclinical. These findings do not establish safety, efficacy, appropriate dosage, or suitability for administration to humans or animals. This material is supplied strictly as a reference standard for in-vitro laboratory research and is not a medicine, supplement or cosmetic.
Storage & handling
Before reconstitution. Keep the sealed vial cool and dark. Lyophilized peptides are stable this way for the period stated on the certificate.
Reconstitution. Add bacteriostatic water slowly against the inside wall of the vial. Swirl gently to dissolve — never shake, as agitation can damage the peptide chain.
After reconstitution. Store refrigerated and use within the window appropriate for the compound under study. Do not freeze once in solution.
Check that the batch code on the label matches your packing slip on arrival.
COA & testing
Every batch is analysed by an independent laboratory before it is listed. The method for this compound is HPLC-UV 214nm.
The certificate shows the main peak purity, the impurity profile, the test date and the laboratory that performed it — tied to the batch code printed on your vial.
