Thymosin α1 is a 28-residue N-acetylated synthetic peptide widely characterised in published immunomodulatory in-vitro research. Full Kiwi Peps profile inside.
The thymosin alpha-1 peptide (Thymosin α1, Tα1) is a 28-residue N-acetylated synthetic peptide corresponding to a fragment of prothymosin α. Published research literature focuses on TLR-mediated (Toll-like receptor) immune-cell signalling in in-vitro models. Thymosin α1 is the reference immunomodulatory peptide in most published research panels.

Thymosin alpha-1 peptide FAQ
What is the thymosin alpha-1 peptide?
Thymosin α1 is a 28-residue N-acetylated synthetic peptide fragment of prothymosin α, cited in published immunomodulatory in-vitro literature.
How is Thymosin α1 different from Thymosin β4?
Thymosin α1 is a 28-residue immunomodulatory reference peptide; Thymosin β4 is a separate 43-residue actin-binding peptide (of which TB-500 is a research fragment).
