Thymosin Alpha 1 5MG
About Thymosin Alpha 1 5MG
Thymosin Alpha-1 (TA-1, also called Tα1 or Thymalfasin) is a 28-amino-acid, N-terminally acetylated peptide originally isolated from the thymic tissue fraction Thymosin Fraction 5. Sequence-identical to the endogenous human peptide, it carries a molecular formula of C129H215N33O55 and a molecular weight of approximately 3,108 g/mol (CAS 62304-98-7). Its acetylated N-terminus is a defining structural feature confirmed by mass spectrometry.
TA-1 is one of the most extensively studied immunomodulatory peptides in the thymosin family. Research literature examines its interactions with Toll-like receptor signaling pathways, its influence on dendritic cell and T-cell maturation, and its modulation of cytokine networks and natural killer cell activity. Because it maps to endogenous thymic biology, it is widely used as a reference tool in immunology and infectious-disease models. Supplied for laboratory research use only.

Research on Thymosin Alpha-1 describes pleiotropic immunomodulatory activity: enhancement of T-cell and dendritic cell maturation, augmentation of natural killer cell activity, and modulation of cytokine expression through Toll-like receptor signaling. It is one of the most clinically investigated thymic peptides internationally, with a substantial literature spanning viral infection, sepsis, and oncology models.
Reported effects derive from cell-culture systems, animal models, and clinical studies conducted outside the United States; findings are context-dependent and not established for U.S. therapeutic use. This material is offered strictly as a research reagent.
Thymosin Alpha-1 was first isolated and characterized in the 1970s by Allan Goldstein and colleagues from Thymosin Fraction 5, a thymic tissue extract. It was among the first thymic peptides to be fully sequenced and synthesized, and under the name thymalfasin it has been developed and studied internationally as an immunomodulator across infectious-disease and oncology contexts.
