What Is Thymosin Alpha-1? A Research Overview
A plain-language research overview of Thymosin Alpha-1 (TA-1) — what the immunomodulatory peptide is, why it's studied, and how purity is verified. Research use only.

Thymosin Alpha-1 — also written TA-1 or Thymalfasin — is a naturally occurring peptide widely studied in immunology research. This overview explains what it is and how to source it for study.
What Thymosin Alpha-1 Is
Thymosin Alpha-1 is a 28-amino-acid peptide originally isolated from the thymus gland. In laboratory research it is characterised as an immunomodulatory peptide involved in signalling around T-cell and immune-cell function.
Why Researchers Study It
Thymosin Alpha-1 is used in laboratory and preclinical models of immune modulation and T-cell signalling. This is experimental characterisation only.
How It Is Characterised in the Lab
Identity and quality are confirmed analytically rather than assumed. A credible research supply confirms identity by mass spectrometry (MS) and purity by HPLC — typically 99%+ — through an accredited (ISO 17025) third-party laboratory, with a per-batch Certificate of Analysis (COA) tied to the exact lot. The CAS reference is 62304-98-7.
