Thymosin Alpha-1 (TA1) is a peptide central to immune-signaling research. Derived from the thymus, it is one of the most-studied immunomodulatory peptides in preclinical literature.
What is Thymosin Alpha-1?
Thymosin Alpha-1 is a 28-amino-acid peptide originally isolated from thymic tissue. In research it is studied for its role in modulating immune-cell signaling, particularly T-cell function.
Studied mechanisms (in-vitro and preclinical)
In preclinical models, Thymosin Alpha-1 is examined for effects on T-cell maturation and immune-response signaling. It is a common tool in immunomodulation and immune-regulation research.
Thymosin Alpha-1 and related research peptides
Thymosin Alpha-1 is often distinguished from TB-500, a fragment of thymosin beta-4 studied in tissue-repair rather than immune contexts. It is also studied alongside immune peptides such as LL-37.
Quality and Certificate of Analysis
Every batch is analyzed by an independent, ISO/IEC 17025-accredited laboratory and ships with its own Certificate of Analysis documenting identity and purity. The COA is batch-specific and available on the product page.
Storage and handling
Thymosin Alpha-1 ships lyophilized. Store cold and out of light, reconstitute with bacteriostatic water, and keep the reconstituted vial refrigerated.
Frequently asked questions
What is Thymosin Alpha-1 used for in research?
It is studied as an immune-signaling peptide in immunomodulation research.
How is Thymosin Alpha-1 different from TB-500?
Thymosin Alpha-1 is studied in immune signaling, while TB-500 is a thymosin beta-4 fragment studied in tissue repair — different peptides with different research uses.
Is Thymosin Alpha-1 approved for human use?
No. It is intended solely for in-vitro laboratory research and is not for human or veterinary use.
How should Thymosin Alpha-1 be stored?
Keep the lyophilized vial cold and out of light; once reconstituted, keep it refrigerated.
