Research Data

What Is Thymosin Alpha-1?

Thymosin Alpha-1 (Tα1) is a 28-amino acid peptide originally isolated from thymic fraction 5. It is the most clinically advanced thymic peptide, approved in 37 countries (as Zadaxin). Research documents dendritic cell maturation, Th1 immune pathway activation, NK cell enhancement, and antiviral activity. Used in COVID-19, hepatitis, and oncology research contexts.

Research Context

  • Dendritic cell maturation and Th1 immune pathway activation
  • Antiviral activity: HBV, HCV, HIV research models
  • NK cell activity enhancement research
  • COVID-19 clinical interest: immune modulation research
  • Cancer adjuvant immunotherapy research — tumor-specific T-cell response

Storage & Reconstitution

Store lyophilized at -20°C. Reconstitute in bacteriostatic water. Use within 4 weeks at 2–8°C. Stable peptide — good shelf life when dry.
