Product Name : Thymosin Alpha-1

Synonyms : Thymalfasin, Tα1

CAS No.: 62304-98-7

Molecular Formula : C₁₂₉H₂₁₅N₃₃O₅₅

Molecular Weight : 3108.3 Da

Appearance : White lyophilized powder

Purity : ≥99% (HPLC), identity confirmed by LC-MS

Amino acid sequence : 28 amino acid acetylated peptide

Thymosin Alpha-1 is a synthetic immunomodulatory peptide consisting of 28 amino acid residues. It is widely applied in immunology preclinical research. It can promote the differentiation and maturation of T lymphocytes, enhance the activity of NK cells and dendritic cells, and regulate the secretion of cytokines such as IL-2 and IFN-γ to balance immune response.

Our product adopts lyophilized powder form for better stability during shipment and storage, with good water solubility for preparing test solution. Batch COA, HPLC and MS test reports are available upon request. Bulk powder and vial packaging are both acceptable.

Storage : Store at 2~8℃, protected from light and moisture. Shelf life: 24 months under proper storage condition.

Product Overview & Biological Function

Thymosin Alpha-1 (Tα1) is a highly conserved, synthetic acetylated polypeptide consisting of 28 amino acids. It is a core immune-regulatory peptide widely used in immunology research, anti-inflammation studies, immune rehabilitation experiments and preclinical immune mechanism exploration.

Tα1 effectively modulates both innate and adaptive immune systems. It promotes the differentiation, maturation and functional activation of T lymphocytes, enhances the proliferation and killing activity of NK cells and cytotoxic T cells, and upregulates the antigen-presenting ability of dendritic cells. In addition, it regulates the balance of multiple cytokines including IL-2, IL-10 and IFN-γ, improves immune suppression status, and exerts anti-inflammatory and immune-enhancing effects in immune-deficiency and inflammatory model studies.

Compared with common immune peptides, Thymosin Alpha-1 features stable structure, high biological activity, no toxic side effects in research models, and excellent water solubility, making it one of the most classic and high-value immune research peptides.

ECHEMI Editorial Reference

Thymalfasin is an immunomodulating agent able to enhance the Thl immune response. Sequence: N-acetyl-Ser-Asp-Ala-Ala-Val-Asp-Thr-Ser-Ser-Glu-Ile-Thr-Thr-Lys-Asp-Leu-Lys-Glu-Lys-Lys-Glu-Val-Val-Glu-Glu-Ala-Glu-Asn.
Thymalfasin is a polypeptide.|Thymalfasin is a synthetic analogue of thymosin-alpha-1, a 28-amino acid protein derived from the precursor protein prothymosin-alpha. Exhibiting a variety of immunoregulating properties, thymosin-alpha-1 induces differentiation of murine T-cell precursors and human thymocytes and the terminal differentiation of functionally immature cord blood lymphocytes and induces production of IL-2, high affinity IL-2 receptors, and B-cell growth factors by peripheral blood mononuclear cells. T-helper and cytotoxic/suppressor T-cell populations are targets of thymosin activity. Thymosin-alpha-1 has been shown to increase the efficiency of antigen presentation by macrophages and to be an endogenous modulator of alpha-thrombin activity. (NCI04)|A thymus hormone polypeptide found in thymosin fraction 5 (a crude thymus gland extract) but now produced by synthesis. It is used alone or with interferon as an immunomodulator for the treatment of CHRONIC HEPATITIS B and HEPATITIS C. Thymalfasin is also used for the treatment of chemotherapy-induced immunosuppression, and to enhance the efficacy of influenza and hepatitis B vaccines in immunocompromised patients.
