Mixing this vial? Calculate your unitsWhat is Thymosin?
Thymosin Alpha-1 (TA-1, INN thymalfasin) is a 28-amino-acid peptide originally isolated from thymosin fraction 5 of the thymus. Its N-terminus is acetylated, which is part of the native structure. Researchers study it for T-cell maturation, cytokine signaling (IL-2, interferon-gamma) and dendritic-cell and natural-killer-cell activity.
This vial holds 10mg as a lyophilized powder. Each lot is HPLC and mass-spec tested, and the lot COA ships with your order. Despite the name, it is unrelated to TB-500 (a thymosin beta-4 fragment).
Thymosin Research Applications
Published work on thymosin alpha-1 includes:
- T-cell maturation and function in cell and animal models
- Cytokine signaling (IL-2, interferon-gamma)
- Clinical trials of thymalfasin in chronic hepatitis B and C and as a vaccine adjunct
Note: Thymosin sold by CoreVionRX is intended strictly for research purposes. It is not intended for human consumption, diagnostic use, or therapeutic application.

What researchers study it for
- T-cell maturation and function in cell and animal models
- Cytokine signaling (IL-2, interferon-γ)
- Dendritic-cell and natural-killer-cell activity
- Clinical trials of thymalfasin in chronic hepatitis B and C and as a vaccine adjunct
Its N-terminal acetylation is part of the native structure and helps stability. Thymalfasin is approved as a medicine (Zadaxin) in a number of countries outside the US; it is not FDA-approved.
Thymosin alpha-1 vs TB-500
The names are similar, but the peptides are unrelated. Thymosin alpha-1 is 28 amino acids (3108.3 g/mol). TB-500 is a seven-amino-acid fragment of a different protein, thymosin beta-4 (889.0 g/mol).
Lab prep: resulting concentration
Dissolving the 10mg of powder in bacteriostatic water gives these concentrations:
| Water added | Concentration |
|---|---|
| 1 mL | 10 mg/mL |
| 2 mL | 5 mg/mL |
| 3 mL | 3.33 mg/mL |
| 5 mL | 2 mg/mL |
Verified before it ships
Every lot is tested by an independent lab before it reaches our shelf: HPLC for purity and mass spectrometry for identity. The lot-specific Certificate of Analysis ships with your order, so you can match the number on your vial to the data.
Storage and handling
- Unopened (lyophilized): store frozen at -20°C, away from light.
- After reconstitution: keep refrigerated at 2–8°C.
- Reconstitute with bacteriostatic water; our free peptide calculator works out concentration for you.
