About Thymosin Alpha-1
Thymosin Alpha-1 is a 28-amino-acid peptide originally isolated from thymic tissue, where it participates in the maturation and regulation of immune cells. As a well-characterized immunomodulatory peptide, it is a common tool for studying T-cell function and innate-immune signaling in research models.
Researchers examine Thymosin Alpha-1 in models of immune modulation, T-cell maturation, antiviral and inflammatory signaling, and cellular-defense pathways. It is supplied as a lyophilized powder for reconstitution in suitable solvent under controlled conditions, manufactured to ≥98% purity with a certificate of analysis available on request. This product is offered for research use only.
