Overview
Thymosin Alpha-1 is a 28-amino-acid N-terminally acetylated peptide originally isolated from thymic tissue, and a standard sequence in immunological and Toll-like-receptor research.
Background
It was purified from thymosin fraction 5 in the 1970s during efforts to identify which components of thymic extract carried immune-modulating activity; it remains one of the best-characterised peptides from that work.
Handling & storage
Reconstitute with our Laboratory Research Reconstitution Solution, running the diluent slowly down the inside wall of the vial rather than onto the powder cake, then swirl until clear — never shake. Store the sealed lyophilised vial at -20°C protected from light; once in solution, hold at 2-8°C and avoid repeated freeze-thaw cycling.
Documentation
Every strength is filled as its own lot and released only after identity is confirmed by mass spectrometry and purity quantified by reverse-phase HPLC. The certificate of analysis shipped with the vial matches the lot and batch printed on its label, and also reports endotoxin, sterility and heavy metals.

Lot release testing for this strength is in progress — the printed lot, batch and COA ID ship on the vial and post here as soon as the certificate is issued. No analytical values are published before the laboratory releases them.
Store sealed vials at -20°C away from light. Allow material to reach room temperature before opening to avoid condensation. Reconstitute slowly against the vial wall using an appropriate sterile diluent, then refrigerate.
