Thymosin Alpha-1
Thymosin Alpha-1 is a 28-amino acid N-terminally acetylated peptide (CAS 62304-98-7), the alpha-1 fragment of prothymosin alpha, originally isolated from calf thymus. In immune cell cultures, its activity is mediated through Toll-like receptor signaling via MyD88-dependent pathways, with documented effects on NF-kB translocation and T-cell receptor signaling cascades in lymphocyte models. It holds the distinction of being the most extensively studied thymic peptide in immunology research and functions as the reference compound for innate immune pathway assays in this peptide class. Supplied lyophilized for in vitro research use only.
