02Mechanism of Action

Thymosin Alpha-1 is a 28-amino-acid N-terminally acetylated peptide derived from the thymic protein prothymosin alpha. Research focuses on its role in T-cell maturation and differentiation and modulation of Toll-like receptors (TLR2, TLR9) on dendritic cells.

It is studied as an immune-modulating tool that influences Th1 responses in immunological assays.

05FAQ

What is Thymosin Alpha-1?

Thymosin Alpha-1 is a 28-amino-acid thymic peptide studied for T-cell maturation and Toll-like-receptor signaling in immune research models. It is sold for research use only.

What pathways does Thymosin Alpha-1 modulate?

In research models it is associated with Toll-like receptor (TLR2/TLR9) signaling and T-cell differentiation toward Th1 immune responses.

What is Thymosin Alpha-1's molecular weight?

Thymosin Alpha-1 has an approximate molecular weight of 3,108.3 g/mol and CAS number 62304-98-7.

How should Thymosin Alpha-1 be stored?

Thymosin Alpha-1 ships lyophilized and should be handled per standard research-peptide practice — kept cold, protected from light and moisture, and reconstituted only for laboratory use. Cold-chain handling is used where required. For research use only.

Is Thymosin Alpha-1 approved for human use?

No. Thymosin Alpha-1 is sold strictly for laboratory research use only and is not a drug or supplement. It is not approved for human or veterinary use or consumption.

How is Thymosin Alpha-1 tested at Ethos Bio?

Every Thymosin Alpha-1 lot is independently verified by MZ Biolabs, a third-party analytical laboratory in Arizona, on a five-point panel — RP-HPLC purity, HPLC-MS identity, endotoxin (LAL), heavy metals, and sterility. A lot-specific certificate of analysis ships with the vial. See How We Test for the full methodology.
