Research details
Thymosin Alpha-1 (Tα1, thymalfasin; Zadaxin) is a 28-amino-acid, N-terminally acetylated thymic polypeptide studied as an immunomodulatory peptide and biological response modifier. Originally isolated from calf thymus and sequenced by Goldstein et al. (1977), it acts at the interface between innate and adaptive immunity. Supplied as a high-purity lyophilized powder in 10mg vials for laboratory research use only.
In the research literature, Tα1 is described as a pleiotropic immunomodulator rather than a tissue-repair or angiogenic peptide. It signals through Toll-like receptors on dendritic cells, driving downstream interferon and T-cell responses via the MyD88 pathway.
Tα1 is a heat-stable, highly acidic molecule. The N-terminal acetylation is structurally important for full biological activity and improves resistance to aminopeptidase degradation, extending the molecule's stability relative to the free-amine form (Liu et al., 2013).
Bergdorf Bioscience offers Thymosin Alpha-1 as a 10mg lyophilized vial with tiered pricing for single-vial pilot studies or multi-vial research kits. Strictly for in-vitro and laboratory research.
Every batch is verified to ≥99% purity by HPLC and ships with a lot-specific Certificate of Analysis (CoA) confirming identity, purity and N-terminal acetylation. Each vial passes documented quality-control checks before release.
We ship Thymosin Alpha-1 worldwide with temperature-controlled, discreet packaging. Lyophilized vials are dispatched promptly and stored refrigerated at 2–8 °C; researchers should follow the lot-specific Certificate of Analysis for handling and reconstitution.
Promotes T-cell maturation via thymic differentiation; activates dendritic cells and NK cells; enhances TLR-mediated innate immune signaling; modulates Th1/Th2 balance.
Advanced protocol
1.6 mg subcutaneously, twice weekly
Note: The dosages listed correspond to typical ranges from published research literature. They do not replace advice from a qualified researcher or physician.
Every batch is analyzed by an independent laboratory via HPLC before shipment. We document purity (avg. 99.43% in 2026), mass spectrometry identity, and sterility. Production follows GMP standards in ISO-certified laboratories.
Thymosin Alpha-1 (TA1) is a 28-amino acid peptide originally isolated from thymosin fraction 5 of the thymus gland. It is researched for immunomodulation and is approved as Zadaxin in some countries.
Each vial contains 10mg of lyophilized Thymosin Alpha-1 with no additives.
Store lyophilized TA1 refrigerated at 2–8°C. After reconstitution, keep it cold and use it promptly.
>=99% purity, verified by HPLC analysis. The Certificate of Analysis is available on our website.
The price per vial goes down with the larger packs. Current prices for the 1, 2 and 3 pack are shown on the product page.
Discreet, tracked parcel shipping. Free shipping from €250.
