Overview
Thymosin Alpha-1, or thymalfasin, is a highly conserved, acidic 28-amino-acid immunomodulatory polypeptide originally isolated from calf-thymus extract in 1977. It is the N-terminal fragment of the precursor prothymosin alpha, N-terminally acetylated and intrinsically disordered in solution.
It is among the most extensively characterized immune-signaling peptides in the literature and serves as an established reference across the recovery category.
