Thymosin Alpha-1

(Research Use Only) Thymosin Alpha‑1 (also known as Thymalfasin or Tα1) is a synthetic 28–amino acid peptide corresponding to a naturally occurring fragment derived from the N‑terminal region of the prothymosin alpha precursor protein. It is supplied as a lyophilized powder for use as a reference material in laboratory, in‑vitro, and analytical studies conducted by qualified professionals in appropriately equipped research facilities. This product is not a drug and is not intended for human or veterinary use, clinical applications, or any form of in‑vivo administration.​​

Structural Information

Thymosin Alpha‑1 is a short acidic polypeptide originally isolated from thymus tissue and later produced synthetically as Thymalfasin for research use. It has been described in the scientific literature as one of the active components of “Thymosin Fraction 5” and is used in preclinical models to investigate thymic‑derived peptides, receptor interactions, and immune‑related signaling pathways under controlled experimental conditions.​

Intended Use and Limitations

This product is supplied for Research Use Only (RUO) and is not intended for human or animal consumption. It must not be used for diagnosis, treatment, cure, or prevention of any disease and must not be compounded, ingested, injected, or otherwise administered to humans or animals. Any scientific literature or background information associated with Thymosin Alpha‑1 is provided solely to describe its chemical and research characteristics and should not be interpreted as guidance for clinical use, immune‑system modulation in patients, antiviral or hepatitis applications, sepsis or HIV management, oncology, vaccine adjuvancy, or other health‑related outcomes.​

Handling, Storage, and Quality

Thymosin Alpha‑1 should be handled using standard laboratory practices appropriate for peptide reference materials, including suitable personal protective equipment and controlled laboratory conditions. Lyophilized vials should be stored according to internal laboratory protocols for peptides, typically in a cool, dry environment protected from light and moisture to help preserve material integrity prior to use.​

Each lot is accompanied by a Certificate of Analysis (COA) providing identity, purity, and analytical data (e.g., HPLC, mass spectrometry), allowing researchers to document material quality and suitability for their specific experimental applications. Users are responsible for ensuring that all work with this compound complies with applicable regulations, institutional policies, and ethical standards.
