About Thymosin Alpha-1
About Thymosin Alpha-1
Thymosin Alpha-1 (CAS: 62304-98-7) is a naturally occurring 28-amino acid peptide first isolated from thymosin fraction 5, a preparation derived from bovine thymus tissue. It is an N-terminally acetylated peptide that plays a central role in immune system maturation and regulation. Thymosin Alpha-1 has been one of the most extensively studied thymic peptides, with research spanning several decades across immunology and infectious-disease research fields.
Mechanism of Action
Thymosin Alpha-1 acts as a biological response modifier, enhancing immune function through multiple pathways. It promotes the differentiation and maturation of dendritic cells, enhancing their antigen-presenting capacity. The peptide stimulates T-cell maturation from progenitor cells via upregulation of T-cell surface markers. It modulates cytokine production, shifting the balance toward Th1 responses, and activates natural killer (NK) cell cytotoxicity. Additionally, Thymosin Alpha-1 signals through Toll-like receptors (TLR-2 and TLR-9) on myeloid and plasmacytoid dendritic cells.

Returns policy →Product Information
This product is intended for scientific research and development purposes only. It is a chemical substance that shall not be used as a drug, medicine, active substance, or ingredient in any product intended for human or animal consumption. Researchers must handle this compound in accordance with their institutional biosafety guidelines. Use only in properly equipped laboratory settings with appropriate personal protective equipment.
Peptides in lyophilized (freeze-dried) form are shipped in sealed glass vials using standard delivery methods and do not require refrigeration during transit. Lyophilized peptides are highly stable at ambient temperatures for the duration of standard shipping (typical transit windows are shown at checkout). Once received, transfer the product to refrigerated storage (2–8°C) promptly.
Frequently Asked
Research peptides are supplied in lyophilized (freeze-dried) form. The amount of material is typically only a few milligrams — appearing as a very thin film or small pellet at the bottom of the vial, often nearly invisible. This is completely normal.
Unlike some suppliers who add bulk fillers (such as Mannitol), CertaPeptides provides pure peptide without unnecessary additives.
