thymosin alpha-1
newImmune research peptide
Thymosin α1 is a 28-amino-acid N-acetylated peptide originally isolated from thymic tissue. In published in vitro and preclinical literature it has been investigated for its role in immune-cell signalling and T-cell maturation models. Supplied lyophilized; purity and identity are reported per lot on that lot’s Certificate of Analysis. For laboratory and research use only — not for human or animal consumption. ROEHN makes no claims regarding its effects.
