About This Compound

What Is Thymosin Alpha-1?

Thymosin Alpha-1 (TA-1) is a 28-amino-acid peptide naturally secreted by the thymus gland. It was first isolated by Allan Goldstein in 1977 as the active component of Thymosin Fraction 5 — a thymic extract studied for immune modulation. A synthetic version (Thymalfasin) has received pharmaceutical approval in some countries for hepatitis B and C treatment.

In preclinical research, Thymosin Alpha-1 is studied for its effects on T-lymphocyte maturation, dendritic cell activation, NK cell function, and regulatory T-cell modulation. It is one of the most extensively studied thymic peptides in immune system research.

Preclinical Research

What Researchers Study Thymosin Alpha-1 For

All published research is preclinical — cell cultures and animal models.

T-Cell Modulation Research
Thymosin Alpha-1 is studied for its role in T-lymphocyte maturation and subset differentiation — particularly Th1/Th2 balance and regulatory T-cell (Treg) activity. Research examines how TA-1 modulates T-cell responses in vitro and in immunocompromised animal models.

Goldstein AL. & Garaci E. (2007) Ann N Y Acad Sci 1112:1-7

Dendritic Cell Activation
Preclinical research investigates Thymosin Alpha-1’s effects on dendritic cell maturation and antigen presentation — key to adaptive immune system priming. Studies examine TLR signaling pathway modulation and cytokine production in DC cultures.

Romani L. et al. (2007) Blood 109(2):543-52

NK Cell & Antiviral Research
Research examines Thymosin Alpha-1’s effects on natural killer (NK) cell activity and antiviral immune responses in preclinical models — exploring its potential as an immune adjuvant in combination research protocols.

Common Questions

Straight Answers.

What is Thymosin Alpha-1 and where does it come from?

Thymosin Alpha-1 is a 28-amino-acid peptide naturally secreted by the thymus gland. First isolated in 1977 by Allan Goldstein, it was identified as the active component of Thymosin Fraction 5. The research compound is a synthetic version. A pharmaceutical form (Thymalfasin) exists for clinical use in some countries — the research compound is sold separately for preclinical research.
What research areas use Thymosin Alpha-1?

Research focuses on T-lymphocyte maturation, Th1/Th2 balance, regulatory T-cell modulation, dendritic cell activation, NK cell function, and antiviral immune response research. All CoreVionRX compound sales are for preclinical research use only.
How does Thymosin Alpha-1 differ from Thymosin Beta-4 (TB-500)?

Despite similar names, these are completely different peptides with different structures and mechanisms. Thymosin Alpha-1 is a 28-aa thymic peptide studied for immune modulation. Thymosin Beta-4 (TB-500) is a 43-aa actin-binding peptide studied for tissue repair. They belong to different protein families.
How do I reconstitute Thymosin Alpha-1?

Reconstitute with bacteriostatic water or sterile water. Typical research concentrations: 1–5mg/mL. Inject water slowly down the vial wall, swirl gently. Store reconstituted solution at 2–8°C.
How should Thymosin Alpha-1 be stored?

Store lyophilized at −20°C, protected from light and moisture. Stable for 24+ months. After reconstitution, store at 2–8°C. Aliquot before reconstituting to minimize freeze-thaw cycles.
