Thymosin Alpha-1 Product Description

Thymosin Alpha 1, also written Tα1 and catalogued under the synonym thymalfasin, was the first peptide isolated from thymic tissue fraction 5 and has been characterized in the literature since the late 1970s. Its sequence is acidic and highly charged, with eight glutamate and three aspartate residues across 28 positions.

The molecule carries an acetyl group on its N-terminal serine, which distinguishes the authentic peptide from unmodified 28-residue analogs and accounts for the 42 Da difference in molecular weight. That modification is reflected in the formula and mass shown below.

Research on this compound sits primarily in immunology, where it is used as a reference reagent in receptor-signaling and cell-maturation assays rather than as a structural or metabolic peptide. The material supplied by BioLongevity Labs is manufactured in the United States and characterized for analytical and experimental evaluation under controlled laboratory conditions.

Compound Specifications

Storage and Handling

• Store the lyophilized compound at -20°C, protected from light and moisture.
• After reconstitution, store at 2°C to 8°C and use promptly; for extended holds, aliquot and store at -20°C to avoid repeated freeze-thaw cycles.
• Maintain aseptic handling and use sterile reconstitution solvent to preserve compound integrity.

Lyophilized Format

This compound ships in lyophilized (freeze-dried) form. Freeze-drying supports long-term storage stability and preserves compound integrity. No fillers are added.
