Thymosin Alpha-1 — compound background
N-acetylated 28-residue thymic peptide
Thymosin Alpha-1 is an N-terminally acetylated 28-amino-acid peptide derived from prothymosin alpha and originally isolated from thymic tissue. It is one of the most-studied immune-modulating peptides, examined for a role in T-cell maturation and immune signalling; the clinical formulation is known as Zadaxin.
Solubility & reconstitution
Highly water-soluble. The sequence is strongly acidic and intrinsically disordered, with no hydrophobic core to resist dissolution, so it takes up water readily.
Commonly worked at 1-5 mg/mL.
Storage
Sealed powder stable at -20 °C. Refrigerate at 2-8 °C.
Commonly worked with for 2-4 weeks at 2-8 °C.
Stability
It carries no methionine, cysteine or tryptophan, so it is not oxidation- or light-sensitive — a comparatively forgiving peptide once the deamidation route is respected.
Reading the Certificate of Analysis
Confirm the mass near 3108 Da and that the N-terminal acetyl group is present (an unacetylated impurity sits 42 Da lighter). Check peptide content separately from purity.
