About Thymosin Alpha-1
Thymosin Alpha-1 (Tα1) is a naturally occurring 28-amino acid peptide originally isolated from the thymus gland and derived from prothymosin alpha. It is studied in research for immune modulation — specifically T-cell maturation, dendritic cell activation, and antiviral defense mechanisms. It is marketed as Zadaxin in some countries with approved clinical indications.
Thymosin Alpha-1 is not related to Thymosin Beta-4 (TB-500) despite sharing a name — they are entirely different peptides with different mechanisms. As a 28-aa peptide, mass spectrometry sequence confirmation alongside HPLC purity is the key quality signal when comparing research suppliers.

Particle PeptidesThymosin Alpha-1 vs Thymosin Beta-4 vs LL-37
Three peptides studied in immune and tissue-defense research — often confused due to naming similarities:
- Origin — Thymosin Alpha-1 is thymic; Thymosin Beta-4 is an actin-sequestering peptide (unrelated to TA-1 despite the name); LL-37 is a human cathelicidin antimicrobial peptide
- Primary mechanism — Thymosin Alpha-1: T-cell and dendritic cell modulation; Thymosin Beta-4: actin dynamics, wound healing, angiogenesis; LL-37: direct antimicrobial activity and immunomodulation
- Research depth — Thymosin Alpha-1 has the most extensive clinical literature of the three, including approved use in several countries; TB-500 and LL-37 are predominantly preclinical
- Common confusion — Thymosin Alpha-1 and Thymosin Beta-4 are frequently conflated due to naming. They share no structural or mechanistic overlap.
Frequently Asked Questions
What is Thymosin Alpha-1?
Thymosin Alpha-1 (Tα1) is a naturally occurring 28-amino acid peptide derived from prothymosin alpha in the thymus gland. It is studied in research for immune modulation — specifically T-cell and dendritic cell activation, antiviral defense, and inflammation regulation. It is marketed as Zadaxin in some countries.
Where can I buy Thymosin Alpha-1?
Thymosin Alpha-1 is sold by research peptide suppliers worldwide. The suppliers above ship to the United States, EU, UK, and other regions with available lab data and certificates of analysis.
What is the difference between Thymosin Alpha-1 and Thymosin Beta-4?
Thymosin Alpha-1 and Thymosin Beta-4 (TB-500) are entirely different peptides. Thymosin Alpha-1 is a 28-aa thymic peptide studied for immune modulation. Thymosin Beta-4 is a 43-aa actin-sequestering peptide studied for tissue repair, wound healing, and angiogenesis. They share the 'Thymosin' name from historical isolation context only.
What should I look for in a Thymosin Alpha-1 supplier?
Look for third-party COAs with HPLC purity confirmation and mass spectrometry for sequence verification. At 28 amino acids, sequence fidelity matters significantly — MS confirmation is the key differentiator between suppliers.
